Wireless Heterogeneous Sensor Networks for the Internet of Things

近年来，小型化、低功耗电路设计、简单、低功耗但相当高效的无线通信设备以及改进的小规模能源供应的进步与降低的制造成本相结合，使一种新的技术愿景成为可能：无线传感器网络。传感器网络由大量传感器/执行器节点组成，这些节点密集地部署在现象内部或非常接近现象。节点的位置不需要设计或预先确定。这使得能够在无法进入的地区或救灾行动中进行随机部署。其目的是开发和促进可扩展的和模块化的无线异构传感器/执行器网络在电子社会中的使用。拟议的研究是从根本上推进我们在过去开发的无线传感器网络应用的工具。特别是，重点将放在物联网（IOT）的无线异构传感器网络（WHSN）上。其目标是开发和促进可扩展的，模块化的，可靠的，安全的和成本效益的WHSN的使用，以满足日益多样化的应用在新兴的电子社会。我们的目标是开发网络架构沿着支持协议和算法以及网络控制机制，用于支持通过不同类型的无线网络进行互操作的传感器/执行器。 我们计划解决和调查设计师在物联网框架内建立此类网络时面临的挑战。重点将放在智能电网、智能车载网络和远程医疗等一系列应用上。根据应用，将部署一种或多种无线网络技术，例如WiMax、WiFi、ad hoc网络、沿着无线网格、因特网接入和LTE蜂窝系统。这是研究目标的一部分，调查工具和技术，为不同的WHSN应用程序的发展。为了实现这一目标，我们将致力于六个不同的主题：1）可持续能源智能电网中的ICT; 2）用于移动和无线电资源管理的认知无线电; 3）移动的云计算架构和系统设计; 4）网络安全和隐私; 5）自组织分布式系统和软件定义网络;以及6）测试床开发。各种架构，协议，算法和软件应用程序的性能评估方法将使用分析和仿真方法以及无线传感器网络测试床的实际仿真和实验室测量进行。

In recent years, advances in miniaturization; low-power circuit design; simple, low power, yet reasonably efficient wireless communication equipment; and improved small-scale energy supplies have combined with reduced manufacturing costs to make a new technological vision possible: Wireless sensor networks. A sensor network is composed of a large number of sensor/actuator nodes, which are densely deployed either inside the phenomenon or very close to it. The position of nodes need not be engineered or pre-determined. This allows random deployment in inaccessible terrains or disaster relief operation. The aim is to develop and facilitate the use of scalable and modular wireless heterogeneous sensor/actuator networks in the e-Society. The proposed research is to advance fundamentally the tools we have developed in the past for Wireless Sensor Network Applications. In particular, the focus will be on Wireless Heterogeneous Sensor Networks (WHSNs) for the Internet of Things (IOT). The goal is to develop and facilitate the use of scalable, modular, reliable, secure and cost effective WHSNs in order to meet the increasing variety of applications in the emerging e-Society. The objective is to develop network architectures along with supporting protocols and algorithms and network control mechanisms for supporting sensors/actuators interoperating via different types of wireless networks. We plan to address and investigate challenges facing designers in establishing such networks within the framework of the IOT. The focus will be on a number of applications such as smart grid, intelligent vehicular networks, and telemedicine. Depending on the application, one or more wireless network technology, such WiMax, WiFi, ad hoc networks, along with wireless mesh, Internet access and LTE cellular systems would be deployed. It is part of the research objective to investigate tools and techniques for the development of different WHSN applications. To achieve this goal, we will be working on six different themes: 1) ICT in sustainable energy smart grid; 2) Cognitive radio for mobility and radio resource management; 3) Mobile cloud computing architecture and system design; 4) Network security and privacy; 5) Self-organized, distributed systems and Software Defined Networks; and 6) Test-bed development. Performance evaluation methods for various architectures, protocols, algorithms, and software applications will be carried out using analytical and simulation approaches as well as actual emulation and lab measurements over wireless sensor network test-beds.
