基于最优能量福利函数优化的传感网路由协议

摘要

为了有效的提高无线传感器网络能量消耗的均衡性，提出了一种基于 Leach 的改进型分簇路由协议Leach-OEW.该路由协议参照最优社会福利函数的概念提出了最优能量福利函数，并将节点最优能量福利函数的预测值应用到簇首的二次选择过程，以此来提高整个网络的能量利用效率以及能量消耗的均衡性.仿真结果表明，与Leach以及PARPEW协议相比， Leach-OEW能够更好的均衡网络的能量消耗，延长网络的生命周期.%In order to improve the energy balance of wireless sensors network, we present a Leach-based routing protocol using Optimized Energy Welfare (OEW) called Leach-OEW. The concept of OEW is raised based on the optimized social welfare. The OEW is applied to the election of the cluster heads in the Leach routing protocol of wireless sensors networks to achieve energy balance as well as energy efficiency. The simulation results show that the improved Leach protocol balances the energy consumption of sensor nodes, prolongs the life time of network compared with the Leach and PARPEW protocol.
