Energy Efficiency Geographic Routing Through Improved Landmark Mechanism in Wireless Sensor Networks

Jianjun Yang, Ju Shen, Tinggui Chen, and Ping Guo

Abstract—Both “local minimum” and energy efficiency are hot issues for Geographic Routing in Wireless Sensor Networks. The local minimum problem is caused by hole that blocks the greedy forwarding process, thus long detour path is produced. Various solutions were proposed to solve this problem. A common approach is to find landmarks and generate a routing path from the source sensor to a landmark node first, then the landmark resumes routing until to the destination to avoid long detour path. However, most existing landmark based geographic routing protocols are energy-inefficient because a constant path is set up prior to routing process, then the forwarding nodes in the path are busy while other nodes are idle even if they are very close to the pre-setup routing path, thus the busy nodes run out of their energy quickly and the hole is larger. In this paper, we present a novel approach, in which the idle nodes near the routing path participate in the forwarding to substitute some busy nodes; therefore, our new mechanism combines geographic routing and energy efficiency routing techniques. Simulation results demonstrate that our approach significantly prolong the lifetime of sensors over peer approaches while almost keep the same short path as state-of-art landmark based routing algorithms.
