Executive Summary

Energy efficiency is one of the critical parameters for the routing protocol in wireless sensor networks. In this paper, two energy efficient algorithms based on the Gradient-Based Routing (GBR) protocol are proposed. First, a Competing algorithm for GBR (GBR-C) is proposed. The core idea in this algorithm is to forward the message to more than one next hop nodes and hence reduce the retransmission and save the related energy. Secondly, a Refilling algorithm for GBR (GBR-R) is proposed which can prolong the lifetime of a network by 'Refilling' new nodes into the network, a process in which new nodes are refreshed in the network.
