| 摘 要： | 鉴于Ad Hoc网络的高移动性,选择一条稳定的路径进行通信尤为重要.文章借鉴AODV按需路由的思想,提出了基于路径稳定性的路由算法PSR(Path Stable based on-demand Routing),通过引入路径有效因子PEF(Path Efficieney Factor)来考虑可行路径的稳定性问题,增强了所选路径的稳定性,减少了由于节点运动引起的链路断裂次数.性能分析和仿真结果表明,与AODV相比,PSR减少了开销,提高了效率,使得算法的性能得到了提升. |

| Abstract: | Due to the highly dynamic topology,stability of selected path is of prime importance in Ad Hoc networks.Based on the idea of AODV,the authors present a novel routing protocol PSR,which uses PEF to find a stable path from the source to the destination.It not only improves the stability of the routing path,but also reduces the probability of link breakage caused by mobility.From performance analysis and simulation results,it can be found that PSR reduces the overhead,improves the efficiency and other performa... |
