Towards the Design of error-free and scalable spatial temporal localization protocols for heterogeneous Wireless Sensor Networks

近年来，三维异构无线传感器网络（HWSN）由于其在未来几代监控、监视、安全和安保系统设计中的潜在应用而受到了极大的关注。在这些类型的网络中，电池供电的自主和异构传感器和执行器设备深深嵌入到物理环境中，配备了不同的传感、计算和无线通信能力。这些自主设备相互协作，以收集、处理和传播有价值的信息，并将收集到的信息报告给中央服务器进行进一步分析，并使感兴趣的第三方可以访问这些信息。HWSNs应用包括：行星探测无线传感器网络、无人机（UAV）无线传感器网络、水下无线传感器网络、油井监测与控制、栖息地和活火山监测、环境观测与预报系统（EOFS）应用、精准农业、战场监测、天气探测、野生动物保护、医疗保健和供应链管理应用，以及其他一些人类无法进入的关键监测领域。以及应急准备和救援应用。

In recent years, 3D heterogeneous wireless sensor networks (HWSN) have received a great deal of interests due to their growing potential use in the design of future generations of monitoring, surveillance, safety and security systems. In these kinds of networks, battery-powered autonomous and heterogeneous sensor and actuator devices which are deeply embedded into the physical surroundings are equipped with different sensing, computing and wireless communication capabilities. These autonomous devices collaborate with each other in order to gather, process and disseminate valuable information, as well as to report the collected information to a central server for further analysis, and making them accessible to interested third parties. HWSNs applications include: planetary exploration WSNs, unmanned aerial vehicle (UAV) WSNs, underwater WSNs, monitoring and control of oil-wells, monitoring of habitat and of active volcanoes, EOFS (Environment Observation and Forecasting System) applications, precision agriculture, battlefield monitoring, weather detection, wild animal protection, healthcare and supply chain management applications, and some other monitoring critical area that are inaccessible to humans, as well as emergency preparedness and rescue applications. Several of these critical applications can be more dependant on the 3D localization system than others, where sensors can be deployed in 3D Surface based environment. The relevance of sensory data and the knowledge of the real-time positions of remote sensor nodes can be very critical in these cases where correct events’ interpretation can life-saving. Thus, sensed events must be ordered both in time and space and proper communication and localization techniques in space and time are required to achieve high accuracy and efficiency. This research proposal aims to explore both the theoretical and practical aspects of spatial and temporal localization in HWSNs. We will concentrate primarly on the design and evaluation of a novel suite of scalable, accurate and efficient spatial-temporal localization protocols to foster the integration of space, time, surface, communication and environmental context into the heterogeneous wireless sensor networks in order to provide the sensed data with both time and position information at anytime and location for any 3D HSWN based applications. The PI is responding to the growing demands of complex 3D heterogenous wireless sensor networks over different kind of 3D surface environment due their wide range of potential applications. The vision of this research in a long-term is to design efficient spatial temporal localization management protocols for multipurpose mult-dimensional HWSNs.
