INTRODUCTION

Recent technological breakthroughs in ultrahigh integration and low-power electronics have enabled the development of miniaturized battery-operated sensor nodes (sensors, for short) that integrate sensing, signal processing, and wireless communications capabilities (Akyildiz, Su, Sankarasubramaniam, & Cayirci, 2002; Estrin, Govin-dan, Heidemann, & Kumar, 1999; Pottie & Kaiser, 2000; Sohrabi et al., 2000; Min et al., 2001; Rabaey et al., 2000; National Research Council 2001). Together with innovative and focused network design techniques that will make possible massive deployment and sustained low-power ...
