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.**

传感、计算、驱动和无线通信的协同集成使各种系统的实现成为可能，这些系统作为解决方案平台引起了广泛的研究关注。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。此类系统的应用范围广泛，包括科学、工业、军事和民用应用。当缺乏可靠运作或成本效益的证据时，就会出现采用技术的障碍。*为了更多地采用这种技术，需要沿着以下方向取得进展：(A)制定可靠性措施，量化它们在恶劣环境中成功工作的能力，在恶劣环境中，节点可能出现故障或随机移动。(B)制定提高其灵活性的方法，以便在不同的应用程序之间更好地共享资源。传感器网络资源共享的增加带来了可扩展、可重复使用和具有成本效益的解决方案基础设施。(C)扩大这些技术的使用，作为新的解决方案平台。由于感兴趣的网络可能在许多方面显著不同，例如核心网络体系结构、单个节点感知和通信设备的限制和能力、节点移动性方面、观察到的现象的特性、组件故障模式和节点故障模式，因此在开发可靠和灵活的无线传感器网络基础设施方面出现了挑战。对于UWSN来说，水流导致的不可控移动性的存在增加了这样的挑战。*为了推进这一领域，该提案寻求沿着以下基本方向做出贡献：(A)提出在节点故障和不可控移动性的概率事件下传感器网络可靠运行的设计原则。(B)提出设计原则，使传感器网络能够在不同应用之间共享资源，同时满足特定应用的服务质量要求。(C)在RFID系统中推进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。*高素质人员的培训将包括设计算法和协议的经验，以解决上述类别网络的可靠性评估问题、资源分配问题和服务质量提供问题。该计划计划在5年的授权期内培养3名博士生、5名硕士生和若干本科生。预计所提供的培训将有助于正在进行的努力，加强加拿大工业在信息和通信技术(信通技术)部门的竞争力。
