Dependable and Agile Services on Classes of Wireless Networks

传感、计算、致动和无线通信的协同集成使得各种系统的实现成为可能，这些系统作为解决方案平台的使用吸引了大量的研究关注。这些系统中最重要的是无线传感器网络（WSN）、无线传感器致动器网络（WSAN）、水下传感器网络（UWSN）和射频识别（RFID）系统。这种系统的应用跨越了科学、工业、军事和民用应用的广泛范围。当缺乏可靠运行或成本效益的证据时，技术采用就会出现障碍。 为了增加这些技术的采用，需要在以下方向取得沿着的进展：（a）制定可靠性措施，量化这些技术在节点可能出现故障或随机移动的恶劣环境中成功工作的能力。(b)开发提高敏捷性的方法，以便在不同的应用程序之间更好地共享资源。增加传感器网络的资源共享导致可扩展的，可重用的和具有成本效益的解决方案基础设施。(c)将这些技术作为新的解决方案平台加以推广。在开发可靠和敏捷的无线传感器网络基础设施的挑战出现，因为感兴趣的网络可能会显着不同，在许多方面，如核心网络架构，限制和能力的个别节点传感和通信设备，节点的移动性方面，属性的现象下观察，组件故障模式，和模式的节点故障。对于UWSNs来说，由于水流而存在的不受控制的流动性增加了这种挑战。 为了推进这一领域，该提案旨在沿着以下基本方向作出贡献沿着：（a）推进传感器网络在节点故障和不受控制的移动性的概率事件下可靠运行的设计原则。(b)提出了在满足特定应用的服务质量要求的同时，在不同应用之间实现传感器网络资源共享的设计原则。(c)推进RFID系统中快速近似计数方法和分组编码方法的理论和使用，以实现新的应用类别。 对高素质人员的培训将包括设计算法和协议的经验，这些算法和协议用于解决上述各类网络上的可靠性评估问题、资源分配问题和服务质量供应问题。该项目计划在5年的资助期内培养3名博士生，5名硕士生和一些本科生。预计提供的培训将有助于加强加拿大信息和通信技术（ICT）行业的竞争优势。

The synergistic integration of sensing, computation, actuation, and wireless communication has enabled the realization of various systems whose use as solution platforms has attracted significant research attention. Foremost among such systems are wireless sensor networks (WSNs), wireless sensor actuator networks (WSANs), underwater sensor networks (UWSNs), and radio-frequency identification (RFID) systems. Applications of such systems span a wide spectrum of scientific, industrial, military, and civil applications. Barriers to technology adoption arise when lack of evidence of dependable operation or cost-effectiveness exists. To increase the adoption of such technologies, advances along the following directions are needed: (a) Developing dependability measures that quantify their ability to work successfully in harsh environments where nodes can fail or move randomly. (b) Developing methods for increasing their agility to allow better sharing of resources among different applications. Increasing resource sharing of sensor networks results in extensible, reusable and cost-effective solution infrastructures. (c) Extending the use of such technologies as new solution platforms. Challenges in developing dependable and agile WSNs infrastructures arise since networks of interest may differ significantly in many aspects such as core network architecture, limitations and capabilities of individual node sensing and communication devices, nodal mobility aspects, properties of the phenomenon under observation, component failure modes, and patterns of node failure. For UWSNs, the presence of uncontrolled mobility due to water currents adds to such challenges. To advance the area, the proposal seeks to make contributions along the following fundamental directions: (a) Advancing the design principles for dependable operation of sensor networks under probabilistic events of node failure and uncontrolled mobility. (b) Advancing the design principles for enabling resource sharing of sensor networks among different applications while satisfying application-specific quality of service requirements. (c) Advancing the theory and use of fast approximate counting methodologies, and group coding methodologies, in RFID systems to enable new classes of applications. Training of highly qualified personnel will include experience in designing algorithms and protocols for solving reliability assessment problems, resource allocation problems, and quality of service provisioning problems, on the above classes of networks. The proposed program plans for training 3 PhD students, 5 Master’s students, and a number of undergraduate students over a 5 year granting period. The training provided is expected to contribute to the on going efforts of strengthening the competitive edge of the Canadian industries in the Information and Communications Technologies (ICT) sector.
