摘　　要：提出一种基于可靠路径剩余生存期(RPL,residual path lifetime)估计的MANET路由发现算法(RLE-RPLP),该算法充分考虑相邻链路剩余生存期相关性,建立优化的多跳路径RPL统计特性分析,提供了更可靠的路由稳定性评估。通过仿真分别与忽略链路RLL相关性的源路由协议及已有稳定性路由协议进行对比。仿真结果表明,RLE-RPLP算法能有效提高网络吞吐量并减少路由重建次数;当节点移动度较高或网络负载较大时,在吞吐量、路由开销等方面均优于已有的稳定性路由对比算法。A novel routing discovery algorithm for MANETs was proposed based on reliable residual path lifetime （RPL） prediction （RLE-RPLP）. Correlation between residual link lifetime （RLL） of neighboring links was explicitly investigated and fully taken into account in stability estimation of multi-hop paths in the algorithm. Optimized RPL statistical proper- ties were further explored to offer a more reliable path stability metric. Simulation analysis demonstrates that the pro- posed RLE-RPLP routing discovery algorithm shows prominent superiority in improving network throughput and reduc- ing route reconstruction frequency. Moreover, compared with the existing link stability-aware routing protocol, the RLE-RPLP achieves better performance improvement in terms of throughput and routing overhead.
