Abstract: Aiming at the energy overhead caused by monitoring the residual energy of nodes in Wireless Sensor Network(WSN), this paper proposes an improved residual energy monitor mechanism for sensors named Improved Residual Energy Scan(IRES), which establishes the similarity models of both the energy information and the location information, and a data aggregation scheme. Experimental results show that IRES can reduce the quantity of data transmission, decrease energy consumption of nodes, and extend the network lifetime.

Key words: network lifetime, energy consumption of node, data aggregation, Wireless Sensor Network(WSN)
