Abstract

Wireless sensor networks (WSN) consist of thousands of tiny and low cost nodes with very limited energy, computing power and communication capabilities. We consider these issues in the design of a simple, Scalable, Energy-efficient Location Aided Routing (SELAR) protocol for WSN. In SELAR, location and energy information of neighboring nodes together with the location information of the sink node are used to perform the routing function. Through simulations, we show that SELAR performs considerably better than flooding in terms of network lifetime, energy distribution, and amount of data delivered.
