摘要
针对移动自组网网络拓扑变化剧烈,传统按需路由协议开销大的问题,提出了一种移动自组网基于距离稳定路由协议(distance-stability routing protocol,DSRP)。传统按需距离矢量协议仅以跳数作为度量值,所选路径容易因断裂而造成重路由。距离稳定路由协议同时考虑通信节点的相对运动性和节点自身在网络拓扑中运动性,引入路由距离稳定度量计算方法,在按需距离矢量协议的基础上增加路由距离稳定值作为选路依据,减少节点通信范围边缘节点参与路由的概率。仿真实验表明,距离稳定路由协议能够选择稳定性更高的路径,提高分组投递率、归一化路由开销及网络吞吐量等网络性能。
To solve the problem that Mobile Ad hoc NETworks topology changes dramatically and high overhead of traditional routing protocol,a Distance-Stability Routing Protocol(DSRP)in Mobile Ad hoc NETworks is proposed.Traditional on-demand distance vector protocols,which only take hops as metric value,are prone to reroute due to link breakage.DSRP considers both the relative mobility of neighboring nodes and node mobility in the network topology.Distance-Stability measurement calculation method is introduced,and the routing Distance-Stability value is added as a routing metric.The probability of nodes at the edge of the communication range participating in routing is reduced.The simulation results show that Distance-Stability Routing Protocol(DSRP)can choose more stable paths and improve network performance such as packet delivery rate,normalized routing overhead and network throughput.
