摘要
无线传感器网络是智能电网广域通信中的基础组成单元,传统的无线传感器网络分簇路由协议虽能在一定程度上简化网络拓扑,但仍存在簇首选择不合理且系统能耗较高的问题。针对此,文中基于粒子群优化算法提出了一种改进的分簇路由协议。该协议利用粒子群算法的参数寻优特性对簇首搜寻方案加以改进,使得新方案考虑了距离、剩余能量、数据传输精度等多种因素。同时还使用粒子群自适应函数对该方案进行优化,从而提高了原算法的可靠性。在能耗实验测试中,所提算法迭代1 300次后的剩余能耗为31.2 J,在对比算法中为最优。而对路由路径的测试中,改进算法的平均运行时延为1.79 ms,平均误码率为0.212 5,在所有算法中均为最低,证明了该算法具有良好的实时性和可靠性。
Wireless sensor network is the basic component of wide area communication in smart grid.Although the traditional clustering routing protocol of wireless sensor network can simplify the network topology to a certain extent,it still has the disadvantages of unreasonable cluster head selection and poor system energy consumption.To solve the above problems,this paper proposes an improved clustering routing protocol based on particle swarm optimization algorithm.The improved algorithm makes use of the parameter search characteristics of particle swarm optimization to improve the cluster head search.The new cluster head search scheme takes into account the distance,residual energy,data transmission accuracy and other factors.At the same time,the adaptive function of particle swarm optimization is used to improve the reliability of the original algorithm.In the experimental test,the remaining energy consumption of the improved algorithm in 1 300 iterations is 31.2 J,which is the best in the comparison algorithm.In the test of routing path,the average running delay of the improved algorithm is 1.79 ms,and the average bit error rate is 0.212 5,which is the lowest among all algorithms.It proves that the improved algorithm has good real-time performance and reliability.
