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.**
