An Novel Energy-Efficient Minimum Routing Algorithm (EEMR) in Wireless Sensor Networks

One of the key problems for wireless sensor networks (WSNs) is the design of energy-efficient routing algorithm, because sensor energy is limited. The energy-efficiency routing algorithm has a strong impact on the network performance. In this paper, we present an energy-efficient minimum routing algorithm (EEMR) of wireless sensor networks. EEMR improves energy utility by changing the activity of wireless communication module of sensor nodes, energy model and state transition of sensor nodes. EEMR employs the minimum angle of source node and goal node, source node and Sink node to prolong network lifetime. Simulation results show that EEMR performs better than DD and EER algorithm for wireless sensor network with high-density deployment and low traffic.
