      abstract = {Next generation Wireless Sensor Networks will operate as self-regulated ad hoc networks of tiny devices that sense, actuate and communicate in a collaborative, autonomous and decentralised manner. This new context aligns with the paradigms of edge and fog computing where it is paramount to reliably distribute data among a large sub(set) of consumer/producer devices. This paper presents a communications architecture for scalable selective data dissemination in wireless sensor networks which is comprised of a decentralised data distribution layer that is tightly coupled to a reliable gradient-based routing protocol. The system supports mechanisms for selective data pushing and pulling within the sensornet where unstructured Peer-to-Peer content distribution concepts are utilised to fairly distribute pieces of data amongst an overlay of consumer and producer nodes. The system has been evaluated under a variety of network conditions and scenarios, both via simulation and real-world deployment, and it is shown to be reliable, scalable, and capable of distributing data in a fair and efficient manner across the network.},

      wind turbine monitoring. The potential for in-situ monitoring of turbine elements, employing
      methodologies that are not possible with existing wired technology, make it possible to attain
      new levels of granularity and autonomy in the monitoring of these structures. Wireless sensor
      devices are limited in terms of communication by the range of their radio modules and, thus,
      need to form networks in order to transfer data from distant points. Routing protocols are primary
      enablers of such ad hoc wireless sensor networks and these require the implementation of
      reliable and energy-efficient mechanisms to maximize network reliability and availability. Existing
      routing protocols cannot be directly applied to the monitoring of wind turbines without
      addressing the unique context and operational characteristics of these structures in multi-hop
      wireless communication. This work identifies the potential effects associated with the operation,
      environment and structure of wind turbines in wireless sensor network multi-hop communication,
      and proposes and evaluates a reliable routing protocol for wireless sensor networks

      publisher = {IACR},
      abstract = {Group Homomorphic Encryption (GHE), formally defined by Armknecht, Katzenbeisser and Peter, is a public-key encryption primitive where the decryption algorithm is a group homomorphism. Hence it suports homomorphic evaluation of a single algebraic operation such as modular addition or modular multiplication. Most classical homomorphic encryption schemes such as as Goldwasser-Micali and Paillier are instances of GHE. In this work, we extend GHE to the attribute-based setting. We introduce and formally define the notion of Attribute-Based GHE (ABGHE) and explore its properties. Our main result is the construction of an Identity-Based Encryption (IBE) scheme supporting homomorphic addition modulo a poly-sized prime ee, which is an instance of ABGHE. Our construction builds upon the IBE scheme of Boneh, LaVigne and Sabin (BLS). BLS relies on a hash function that maps identities to etheth residues. However there is no known way to securely instantiate such a function. Our construction extends BLS so that it can use a hash function that can be securely instantiated. We prove our scheme IND-ID-CPA secure under the (slightly modified) etheth residuosity assumption in the random oracle model and show that it supports a (modular) additive homomorphism. By using multiple instances of the scheme with distinct primes and leveraging the Chinese Remainder Theorem, we can support homomorphic addition modulo a ``large'' (i.e. superpolynomial) integer, the first such IBE scheme. We also show that our scheme for e>2e>2 is anonymous assuming the hardness of deciding solvability of a special system of multivariate polynomial equations. Finally, we define a primitive for attribute-based group homomorphisms in the multi-key setting, introduce an important security property and present a generic construction of the primitive meeting this security property.},

      abstract = {As a result of increasing demands from the off shore industry’ Underwater Wireless Networking (UWN) has attracted special focus in recent wireless communication studies. Owing to the physical characteristics of the underwater channel, various Electro-Magnetic (EM), optical, and acoustic communication technologies have been applied to UWN for different communication ranges. EM waves have wide frequency bands and fast propagation speed, but the attenuating nature of sea water severely constrains the communication range. Underwater optical communication has advantages in bandwidth and propagating speed, yet its communication range is limited by the absorption and backscatter in water. Acoustic waves have the longest transmission range in underwater environments, but encounter challenges in the temporally and spatially varying underwater acoustic channel. Long propagation delays, bandwidth constraints and high error rates are frequently cited challenges. Acoustic and optical carriers are the two modes of communication most seriously considered by researchers, with the bulk of attention paid to acoustics because of its relative simplicity - it is treated the same as EM in the air, except for long propagation delays. Optics, on the other hand, is much more complicated. Aside from its short underwater communication range, optical PHY links are typically line of sight and usually uni-directional, requiring relative localization among communicating nodes. At the same time, these properties give optics the potential for covertness, since a finely aligned optical beam can help elude detection or interception. These different characteristics and propagation properties provide some very interesting trade off scenarios, and motivate the combination of different techniques to create a hybrid approach},

Much less attention has been paid to the practicalities, in terms of ensuring that the end-user experiences little or no loss in the quality of their network services when the handover occurs. In this paper, a methodology for managing such handover traffic in a WiFi network is proposed. The approach integrates and leverages aspects of three quality control mechanisms to enable stable, higher quality delivery of enhanced WiFi network services. It combines i) information adduced from a theoretical model with ii) a low complexity Quality of Experience metric that is quick and easy to estimate and iii) a queue management scheme.},

      abstract = {The content and means of delivery of many electronic and computer engineering courses has evolved radically over the past decade due to the rise in the availability of affordable, open-source programmable microcontrollers and accessible wireless communication devices. Many engineering modules have been extended to more closely integrate the underlying technologies and systems with modern engineering practice.
      One of the more exciting additions to the range of inexpensive robotic technologies is unmanned aerial vehicles (UAVs), or drones. Drones have a wide range of real-world applications and the full potential of these devices has yet to be explored by either industry or educators.
      Drones have an enormous capacity to engage students and facilitate classroom learning. Drones offer a challenging platform for existing engineering design modules where students face challenges in electronics, control, programming and project management.
      However, one of the challenges facing educators is how to integrate drones within their courses in a meaningful way; so that UAVs are not viewed as mere toys, but as devices that have a credible role to play in the solution of real world problems. In this paper we describe how UAVs have been included across multidisciplinary projects where students work on real world problems that span a broad range of engineering disciplines. The projects draw on the capabilities of UAVs: the ability to sense objects in their surroundings, to plot and maintain an accurate course, to make on-the-fly adjustments based on environmental data, to use computer vision to interpret data gathered by the on-board camera etc.
      As a proof-of-concept we focus on a practical, contemporary engineering task – the use of UAVs to monitor the structural health of next generation wind turbines. We describe the high level task, decompose it into multiple complementary facets, relate those to specific engineering disciplines and associated educational concepts at both undergraduate and postgraduate levels, and then present specific learning and developmental opportunities and describe and present the student engagement and achievements.},

      abstract = {Underwater Communications is very much an experimental science because of the complex medium - the water - and its unpredictable propagation properties, thus mandating experiments to validate theory. The medium is particularly challenging for the transmission of acoustic and optical signals. Thus, the true performance of a transmitter/receiver system can be evaluated only in the water. It would then appear that UW research be inevitably associated with a testbed. However, this is not always the case because UW testbeds are difficult to set up, calibrate and instrument. The purpose of the recent NSF CRI Ocean-TUNE project is precisely that of deploying inexpensive UW testbeds accessible by the Community. UCLA, as a participant in the Ocean-TUNE project, has recognized that one UW testbed cannot fit all applications and therefore has been developing WaterCom, a multilevel testing platform consisting of three testbeds - small, medium and large scale. The small testbed is deployed in a tank, with two modems; it is used for point-to-point communications at close range. It is instrumented for remote access and allows the testing of variable {TX} power values with different obstacles, reflected rays absorption and water purity values (for optical experiments). The medium scale testbed, deployed at the Marina del Rey UCLA boathouse, will enable remotely monitored experiments of MAC and network protocols with three nodes, one of them mobile. The large scale open water testbed is deployed in the Catalina channel. It will employ OFDM Modems as well as small submersible, mobile platforms. WaterCom will enable two types of experiments: environment measurements, like subsurface currents, presence of deposits in the water, etc, and; network protocol and application measurements in the open water. The paper describes the testbeds in detail and introduces preliminary small scale testbed measurements.},

Many analysts question the sustainability of this growth, highlighting pressures on food supplies, energy resources and the detrimental impact of so many people on our environment. A notable facet in this population growth is the aging population demographic in developed countries. Advances in knowledge, understanding and treatment of medical conditions mean that people are living longer, and with better quality of life, than in previous generations.
      These life-improving advances are not limited solely to the medical sphere - science and engineering are contributing significantly to supporting, sustaining and maintaining active, healthy and independent living amongst these aging populations. Mobile and wireless technologies have been playing an increasingly important role in this domain - enabling timely, localized and personalized interactions between individuals and service providers. In this context we explore the potential benefits that 5G offers an aging population. We consider a number of end-user mobility scenarios, and highlight how ongoing vehicular research is rapidly converging to enable future autonomous vehicular solutions that scale from rural countryside to dense urban deployment scenarios.},

However, there is still much debate on the most effective mechanisms for acquiring such skills.
      Engineering students can be extremely resistant to the notion of individual or collective reflection and often find it difficult to function successfully in a group setting. This paper reports on how co-operative learning has been integrated into a largescale, practical freshman Engineering laboratory module, and explores the student experiences of being encouraged to engage in meaningful reflection. In particular, it details the presentation modalities and phenomena that influence the engineering students attitudes toward cooperative learning and reflection.},

There has been limited success so far achieving homomorphic encryption in the functional setting; that is, for primitives such as Ciphertext-Policy Attribute Based Encryption (CP-ABE) and Identity Based Encryption (IBE). We introduce a new primitive that captures homomorphic encryption with support for access policies and policy composition. We then present a generic construction using CP-ABE and multikey Fully-Homomorphic encryption (FHE).

      abstract = {This paper reports on the category of ``self-affirmation'', one of the key abstracted categories identified in a qualitative study that sought to examine the factors that influence success in undergraduate computer science. This substantive study employed the grounded theory methodology and explored the factors contributing to success from the students' perspective. Self-affirmation refers to the processes by which an individual seeks to make sense of their own actions and of the world around them. These processes are usually considered as a defensive mechanism as they may be activated in response to the typical setbacks and negative events of daily life. For example, a student may seek to rationalise poor academic performance by deciding that they have no aptitude for the subject in question or they may accept their poor performance and use it as a motivation for change. Alternatively, an individual may seek out positive experiences to help them recover from negative events e.g. someone who is feeling unhappy with one aspect of their life may seek out positive experiences to make them feel better. In this paper we explore the self-affirmation processes that influenced and shaped participants attitude towards their studies, which in turn influences achievement and success. Self-affirmation varied along a continuum from positive to negative. Participants experienced positive feelings when they were successful in completing a computer related task or when their skill and ability was praised by academics and tutors. The participant's belief in their own ability was affirmed as a result of these interactions. At the negative end of the continuum, participants described the influence of negative feedback from their teachers and peers. They described how they found this negative feedback to be discouraging, leading them to become anxious and worried about their decision to study computer science. The grounded theory approach adopted in this study provided a unique insight into the students' perspective of the key factors that influences their success. Self-affirmation processes emerged as a key element of this theory and merit inclusion in future efforts to support and scaffold freshman learning in computer science.},

      abstract = {Quality-oriented network service provisioning can take place at the network level using estimates of Intrinsic Quality of Service (IQoS) parameters or at the user level through measurements of the end-user Quality of Experience (QoE). While IQoS parameters are quantitative and measurement based, QoE estimates are more difficult to obtain as they usually rely on subjective end-user reporting. A new metric for the instantaneous estimation of QoE is proposed, expected Quality of Service (eQoS). This Perceived Quality of Service metric is calculated using IQoS parameters.
      eQoS estimates the QoE of common real time services for mobile devices (e.g. smartphones, tablets): Voice of IP via Constant Bit Rate, Audio and Video streaming via Variable Bit Rate.
      The efficiency of the proposed eQoS metric is evaluated via a realisation of an infrastructure-based wireless network. Unlike existing QoE metrics, eQoS provides an instantaneous estimate of the perceived QoS thereby establishing eQoS as an essential parameter for inclusion in future traffic management algorithms.},

Once published, metadata corrections can only be effected by a complete republish/swarm recreation or for each peer to manually make corrections (causing them to leave the swarm, decreasing performance). This work presents an approach which enables a swarm to collaboratively upgrade embedded data to reflect changes in metadata, and to identify additional candidates which contain differing metadata but a correct payload. Swarm degradation due to peer drop-off resulting from edits is eliminated, and additional peers can be identified in a fully automated fashion, increasing swarm lifetime and performance. Arising from this metadata abstraction, automatic purification can be realised in situations where multiple incomplete/incorrect versions are available within one or more unconnected swarms. Variations associated with a content set are processed associatively using a knowledge discovery rule set to extrapolate a canonical tag set, which can also be reinforced using data from external corpora. After any update, these changes can again be automatically disseminated in a peer-to-peer swarm. The system presented enables context-aware P2P data transfers which abstract metadata optimally, while also maximising swarm size and enabling cataloguing of content. A proof-of-concept implementation is presented, and its impact on swarm purification/ optimisation is evaluated},

Looking to the future, it is foreseen that billions of small Internet-enabled, ubiquitous devices will provide digital intelligence and connectivity for almost every leisure, commercial and industrial product. Interconnectivity through the Internet will facilitate seamless interfacing and interactivity with many aspects of our lives; providing smart operations in both commercial and personal settings. Wireless Sensor Networks (WSN) are hailed as one of the key enabling technologies of this ubiquitous vision and such infrastructure is commonly realised using small, low power, low data rate, wireless devices with sensing and actuating capabilities. In this paper we detail a practical laboratory task where final year undergraduate students design, implement and validate an inferred security wireless sensor access system. We evaluate the students’ experience of working with the Sun Microsystems SunSPOTs and explore how their perception of both ubiquity and security evolves from inception to completion of the activity.},

Indeed, students typically view programming modules as necessary pre-requisites for progression beyond the freshman years, rather than as a means to help them develop their critical thinking and problem solving skills. Over the past decade the Programming Support Centre in Trinity College has sought to provide a positive, supportive atmosphere where students can voluntarily seek one-to-one or small group assistance with challenges they face while learning to program. During that time the Centre's service offering has evolved to meet changes in students’ needs and to appraise faculty members of novice programmers perceptions of the challenges they face when attempting a programming assignment. We assess the Centre’s impact on student learning and detail how the natural tensions that exist between students, the Centre staff and faculty members have been mitigated. We discuss the qualitative and quantitative metrics used to assess the performance of the Centre over the past decade and suggest ways in which it may evolve in the course of the next ten years.},

Institutions within the engineering community such as Engineers Ireland, the Accreditation Board for Engineering and Technology, the Royal Academy of Engineering and members of the CDIO (Conceive Design, Implement, Operate) initiative have highlighted a need for new approaches to learning and teaching of engineering within our academic institutions. This paper reports on the recent implementation of project based design courses in both of the two engineering programmes offered by Trinity College Dublin. The projects are each carried out in small groups (typically four to six) and are virtually free of podium based teaching. Initially, the students are provided with a design brief, foundation level technical input and raw materials. The projects are developed around the principles of CDIO which represents best international practice for teaching design. The implementation of this methodology requires self-directed learning, teamwork and small group learning, culminating in the actual building and testing of a prototype. Some projects finish with a public competition which tends to generate huge excitement. The new courses have been seen to foster innovation and to provide a format that channels the student’s creative skills in a coherent and structured manner. The detail of the courses, the learning outcomes, and the resource overhead are presented as well as a discussion on the initial results from the programmes.},

Routing tables which are populated with an “out of date” view of the neighbourhood produce an overhead in the routing process which can affect the QoS of the communication and the stability of the network interconnectivity. To maintain correct network state information, periodic “Hello” messages are often employed. In many scenarios these may be expensive in terms of communication and energy. Providing a node with an ability to estimate mobility has been proposed as a mechanism for regulating the transmission of discovery “Hello” messages and for prompt updates of its neighbourhood view. In this paper, a mechanism for gauging the relative mobility of a node with respect to its neighbourhood is presented for mobile Wireless Sensor Networks. The algorithm employs a set of Bloom filters to encapsulate opportunistically eavesdropped data from neighbours. A set of mobility states is defined using a model based on the number of neighbours recently cached, a membership comparison of Bloom filters, and a probabilistic expression. The mechanism detects changes in the neighbourhood using only the available information. The evaluation of the system has been performed (using a gradient-based routing protocol) in the TinyOS simulator, Tossim.},

The corresponding energy model accurately approximates the energy decay characteristics for applications exhibiting different energy usage profiles. It adapts to the prevailing load conditions, and can be used by applications supporting self-learnt or over-the-air reconfiguration of nodes within the wireless sensor network.

      abstract = {TinyTorrents integrates Wireless Sensor Networks with the BitTorrent Peer-to-Peer protocol and is designed to respect the resource constrained environment which characterises many WSN's. This paper describes the architecture and design which underpins the TinyTorrents system and explores many of the technical challenges that arise in the fusion of such distinct data dissemination networks. The key behaviours and features of both peer-to-peer and wireless sensor networks are first explored and evaluated. TinyHop, the protocol used for inter-node routing within the WSN, is presented. Experimental resource optimization and system analysis is performed for message overhead, resource coordination, peer selection and tracker functionality. The system advertises available node and network data via both Web 2.0 service interfaces and through BitTorrent tracker networks. The system has been validated and demonstrated using multiple networks and multiple clients accessing data on a global scale.},

In this paper, a novel two layered scheduling approach that addresses this challenge in a UMTS based HSDPA network is presented. The first layer carries out resource reservation for different traffic classes while the second layer dequeues packets on the basis of the reported channel quality indicator value and buffer occupancy. Simulation results show that the algorithm has low latency and jitter for VoIP services, whilst achieving better total cell throughput and fairness properties in comparison to several other well known scheduling algorithms. The performance of the algorithm for video streaming has also been evaluated in terms of peak signal to noise ratio (PSNR).},

To this end, the authors have developed the TinyTorrents system; a peer-to-peer publishing and redundancy framework for the dissemination of sensor data in a reliable, redundant and self-consistent manner using torrent technology. TinyTorrents utilises a reactive routing protocol for WSNs which incorporates bidirectionality, reliability and generic communications modalities. In this paper the routing protocol, TinyHop, is presented. Tiny-Hop creates on-demand routes, is self managed and works in an end-to-end fashion. Any node in the mobile environment can establish communications with, and retrieve data from, any contactable node at any time. Thus any node can function as a base station or sink. Mobile elements (e.g. data mules) or static gateways can interconnect from different parts of the network, thereby balancing the traffic load and helping avoid network partition. The protocol has been implemented in TinyOS 2.0.2 and simulated in TOSSIM},

As well as undertaking formal modules, graduate students on these programs are expected to quickly learn how to plan, manage and conduct research. They should also know how to present the outcomes of their research in peer- reviewed publications. Moreover, they must be able to reflect critically on existing research as well as on their own findings. In the development of one such integrated Ph.D. program it was found that there is little agreement on the constituent elements of a module on computing research methods or on the pedagogical principles to be employed in the preparation and delivery of such a module. This paper reports on the design, experience and assessment of a graduate level module on research methods in computer science, documenting how it was planned and realised, reporting on the staff and student experiences, and providing both objective and subjective assessments of the module and its outcomes.},

Most AQM algorithms are primarily designed to improve congestion control through early notification. However, significant work has been done on more advanced AQM schemes designed to protect responsive flows against unresponsive traffic. Such schemes are designed to identify and penalise unresponsive flows, which may use an unfair share of the available resources. We evaluate six algorithms through simulation-based experiments. The schemes chosen employ lightweight mechanisms for approximating fair bandwidth sharing. They are designed to be scalable and allow for incremental deployment in the current best-effort Internet infrastructure. Evaluation of their performance is effected under various network traffic conditions. The operational complexity of the schemes is also assessed.},
