Array Signal Processing in Wireless Sensor Networks

Recent advances in Integrated Circuits (IC) and Micro Electro Mechanical Systems (MEMS) technologies have allowed the design and construction of low-cost low-power smart sensor nodes with sensing, computing, signal processing and wireless communication capabilities that can form distributed wireless sensor network systems. Wireless sensor networks have been recognized as one of the most important technologies in the 21st century, and the systems hold the promise to revolutionize the sensing paradigm and can be used to perform detection, localization, tracking, and identification of objects in a broad spectrum of military, scientific, industrial, and home applications like infrastructure health monitoring, disaster management, and battlefield surveillance [1].
