Next Century Challenges: Scalable Coordination in Sensor Networks Deborah Estrin Ramesh Govindan John Heidemann Satish Kumar USC/Information Sciences Institute 4676 Admiralty Way Marina de1 Rey, CA 90292, USA {estrin,govinda.n,joh,kkumar}@isi.edu Abstract Networked sensors-those that coordinate amongst themselves to achieve a larger sensing task-will revolutionize information gathering and processing both in urban environments and in inhospitable terrain.
