The emerging field of wireless sensor networks combines sensing, computation, and communication into a single tiny device. Through advanced mesh networking protocols, these devices form a sea of connectivity that extends the reach of cyber space out into the physical world. Unlike traditional wireless devices, wireless sensor nodes do not need to communicate directly with the nearest high power control tower or base station, but only with their local peers. This paper presents the power of wireless sensor networks lies in the ability to deploy large numbers of tiny nodes that assemble and configure themselves. Usage scenarios for these devices range from real time tracking, to monitoring of environmental conditions, to ubiquitous computer environment, to in situ monitoring of the health of structures or equipment.
