摘　　要：基于跳数的无线传感器网络路由协议因实现简单、延迟少和易维护等优点,一直以来受到广泛关注。在分析现有基于跳数的路由协议的基础上,对最小跳数路由算法的选路标准进行了改进,提出了一种基于路径质量的无线传感网路由协议,采用跳数、综合链路质量和节点能量作为路径质量的度量指标。使用OMNET++网络仿真软件进行了仿真实验,实验结果表明:改进后的路由协议有效地提高了网络分组的投递率,降低了网络的能耗。In wireless sensor networks,routing protocol based on hop count has attracted extensive attention due to its advantages such as simple implementation,low latency and easy maintenance.This paper analyzes the existing routing protocols based on hop count,improves the routing standard of the minimum hop routing algorithm,and proposes a routing protocol based on path quality(PQR)in wireless sensor networks,which uses hop count,global link quality and node energy as the metrics of path quality.OMNET++network simulation software is used to carry out simulation experiments.The experimental results show that the improved routing protocol effectively increases the delivery rate of network packets and reduces the energy consumption of the network.
