EAA: ENERGY AWARE ANYCAST ROUTING IN WIRELESS SENSOR NETWORKS

Since the emergence wireless sensor networks (WSNs) energy constraint always remain an issue which affects its design and operations. Many techniques have been proposed to lessen the consumption of energy in WSNs. By discovering the loop holes in the existing techniques we propose an energy aware anycast routing protocol (EAA) for wireless sensor networks in this paper. EAA distribute the sensed data among the existing nodes in a cost efficient manner to gain maximum network lifetime. Through extensive simulation results in TOSSIM, it is demonstrated that the EAA outperforms the existing techniques in terms of energy consumption which leads to maximum network lifetime. According to the average results EAA save almost 9.1% energy at every node of the sensor network. It minimizes the header to payload ration which leads to maximum network lifetime and 40% improvement has been recorded.
