Power Control-based GRACE (PC-GRACE) Routing Protocol for Wireless Sensor Networks

This paper investigates an Adaptive Power Control based Energy Efficient Routing scheme, referred to as PCGRACE, which takes advantage of both efficient energy utilization and transmission power control strategy. Thus, transmission power control strategy is incorporated with energy efficient routing. Experimental results are obtained by using the Sun SPOT-based wireless sensor test bed. The experimental results show that the routing technique results in an increase in the energy efficiency of the network and thus, an improvement in the network lifetime.
