ABSTRACT: Self-configuring wireless ad hoc networks have attracted considerable attention in the last few years due to their invaluable civil and military applications. While current research in this area is still focused on finding and maintaining valid paths between source and destination, the energy efficiency, though crucial to prolong the network lifetime and thus make the network more survivable for the application, has been studied insufficiently, especially in low-cost large networks, where the simplicity is the major concern. Energy efficient routing strategies proposed in literature either do not take advantage of the sleep mode to conserve energy more efficiently, or incur much overhead in terms of control message and computing complexity for the sleep scheduling and thus is not scalable. In this dissertation, a novel strategy is proposed to manage the sleep schedule of the nodes in the network so that energy can be conserved and network connectivity can be kept. The novelty of the strategy is it's extreme simplicity.
