ABSTRACT
In the households of the developed countries, the number of processors in use far exceeds the number of personal computers on the desktop. Most gadgets that have become indispensable for us contain one or more processors. A state-of-the-art automobile has fifty or more microprocessors in it. These sense various conditions and actuate devices for our safety or comfort. With the advancement of technology, the physical size of the processors has diminished, and a new breed of applications has emerged that relies on miniature dust-size processors sensing physical parameters, and performing wireless communication with one another to achieve a collective goal. The primary job of a sensor network is tracking and monitoring. Estrin et al. [EGH+99] summarizes the endless potential of sensor networks that range from ecological monitoring to industrial automation, smart homes, military arena, disaster management, and security devices.
