Maximum Energy Routing Protocol Based on Strong Head in Wireless Sensor Networks

Sensor node has a limited amount of battery in sensor network. So, it is very important to have the maximum lifetime of network through energy effective routing. To continue maximum lifetime between sensor nodes, it is necessary to utilize efficient clustering algorithm. LEACH is a well known routing protocol based on cluster, but it has several problems about short network lifetime because of the inefficient energy consumption. In this paper, we propose a routing protocol called Maximum Energy routing protocol based on Strong Head (MESH) in order to solve the problems of LEACH. The key idea of our protocol is that the collected data from cluster head is transmitted to SINK by node defined as a "Strong Head\´. We evaluate the performance of our protocol through simulations. Simulation results show that our protocol outperforms the LEACH in terms of the energy consumption and lifetime of the network.
