An Energy Efficient Routing Algorithm Based on Radar Chart for Wireless Sensor Networks

In wireless sensor networks, energy conservation has been the most important design criterion for the routing algorithms. In order to reduce overall energy consumption and prolong the network lifetime, an energy efficient routing algorithm based on radar chart (EERC) is proposed in this paper. This routing scheme adopts multiple individual metrics to determine the selection of the next hop, which contains the node residual energy, the distance from the node to the sink, and the distance between the node and its neighbors. Then a comprehensive evaluation model for alternative nodes is built based on radar chart. Finally the node with maximum evaluation value is selected to be the next hop. Simulation results show that the proposed algorithm decreases the energy dissipation and extends the lifetime of the network.
