Distributed Signal Processing in Wireless Sensor Networks

Abstract

Sensor nodes forming a network and using wireless communications are highly useful in a variety of applications and scenarios. Such a wireless sensor network can be used to collect and process information from the field in military surveillance, building security, in harsh physical environments, and for scientific investigations on other planets. Sensor networks can perform distributed computations in the network for a number of interesting applications, including signal and image processing to detect object signatures, track detected objects in the field, statistical computations, etc. The objective of this research project is to develop time efficient distributed algorithms over wireless networks for some well known signal processing applications. Specific research problems include detection and tracking of objects using sensor data, application driven signal processing, and collective communications in wireless sensor networks.
