Project Overview
Wireless sensor/actor networks (WSANs) have been identified as one of the most important technologies for the 21st century. Recent advances in wireless communication, micro-electro-mechanical systems and low power and highly integrated digital electronics have enabled the deployment of low cost, low power, multi-functional sensor nodes that communicate wirelessly. This has made possible a new range of applications include military sensing, infrastructure security and counterterrorism applications, air traffic control, traffic surveillance, video surveillance, industrial and manufacturing automation, distributed robotics, environment and habitat monitoring, medical applications and many others.The underlying aims of the project are to improve monitoring and controlling of WSANs by providing a unified management framework for them. This framework can be exploited by different applications to provide a satisfactory life-time, reliability, accuracy, efficiency, self-configuration, reconfigurability and flexibility.
The specific aims of the work are:
a) To define the required functions and tasks needed for managing the network properly; and to define the form of information needed to represent the current state of the network and the QoS parameters.
b) To design a network management model for placing the required tasks and functionalities in a structured framework.
c) To design a lightweight network management protocol as a tool for exchanging management information between the different nodes.
We divide the management functions into five categories: energy management functions for monitoring the power level of the different nodes and controlling how a node should use its power, fault management functions for detection and resolution of node problems, mobility management functions for detecting and registering the movement of nodes so that network connectivity is always maintained, quality of services (QoS) management functions responsible to quantify, measure, report and control the performance of the network so that it provides the user requirements and security management functions. The project will investigate how the network status can be presented, what are the tasks needed to manage the network, how to implement these tasks and functionalities and design a protocol to exchange the management information.
