Abstract: Energy consumption is crucial issue in wireless sensor network. Typically in a sensor network moves on a low traffic load but in case of detection of an event it becomes high. In high traffic load situation, a lot of packets forwarded and also collisions increased. Due to increased collision and a lot of packets forwarding consumes a lot of energy of a sensor node. A few media access control (MAC) protocol has been proposed to handle the variety of both light and heavy traffic load situation among them RC-MAC is one which allows switching of modes to handle different traffic loads. In RC-MAC, nodes waste energy to stay awake and create energy hole in a network. In order to better utilize the conserve energy of a sensor node, we propose a energy hole mitigation technique of Receiver-Centric MAC (RC-MAC) which has better energy conservation and better throughput than RC-MAC. The proposed research work uses a beacon technique that lets nodes to get sleep appropriately between data transmission and change the data routing path to avoid energy hole problem.
