Energy Cost Based Energy Optimized Routing Algorithm in WSN
WSN中基于能量代价的能量优化路由算法

Aiming at the energy consumption issue of sensor nodes for routing algorithm in wireless sensor networks, an energy cost based energy optimized routing algorithm was proposed. Based on the comprehensive consideration of the efficicncy and balance of energy consumption of sensor nodes for data transmission, a new energy cost function was exploited, which achieved optimal matching between energy efficiency and balance. Sensor nodes compute the energy cost of its forward neighbors using this function and select the node with the minimum energy cost as its next hop. In the algorithm, the routing decision is made according to the information of neighbor nodes, with lower computational time complexity. Finally, the performance of proposed routing algorithm was simulated and compared with typical routing algorithms. Simulation results show that the algorithm can extend the network lifetime effectively, economize and balance the energy consumption of sensor nodes.
