摘要

摘要: 针对移动Ad hoc网络动态拓扑特性，该文提出一种以可靠路径稳定度估计为基础的多路径路由优化算法。该算法从路径剩余生存期统计特性出发，充分考虑相邻链路生存期相关性，从而消除已有算法在路径稳定度估计中存在的理论误差，并利用优化后的稳定度准则实现路由发现进程的多路径选取和基于备用路径支持的快速路由修复。仿真对比结果表明，该算法具有较快的收敛速度，能够有效提高网络吞吐量，缩短数据传输时延并降低路由开销，更好地保证较高节点移动度下的数据传输稳定性。

Abstract: To deal with dynamic network topology in Mobile Ad hoc NETworks (MANETs), a reliability-enhanced multipath source routing algorithm is proposed based on accurate path stability estimation. In order to eliminate theoretical errors existing in current approaches, statistical properties of residual path lifetime are exploited by fully introducing correlation among neighboring links residual link lifetime. Optimized link and path stability metric is then provided to realize a multipath-enabled routing discovery procedure and a backup path-support fast routing recovery mechanism. Simulation results show that the proposed routing algorithm can achieve fast routing discovery convergence, increase network throughput, reduce data transmission delay, and lower routing overhead. Furthermore, high network reliability can be well guaranteed even under high node mobility degree.
