Wireless sensor networks consist of small battery powered devices with limited power resources. Once deployed, the small sensor nodes are usually inaccessible to the user, and thus replacement of the power source is not feasible. Hence, power efficiency is a key design issue that needs to be enhanced in order to improve the life span of the network. Several network layer protocols have been proposed to improve the effective lifetime of a network with a limited power supply. By comparing existing sensor network routing protocols, this paper proposes an improvement algorithm based on MTP agreement and using the Minimum sending distance (M-MTP).
