针对移动自组织网络(MANET)，提出了一种基于按需距离矢量(AODV)的优先路径选择概率多径路由协议(AODVM-PPSP)。该协议引入了一种新的方法，在最佳选择策略和中等负载均衡策略之间有意识地选择合适的策略，为每个节点提供相应的优先路径选择概率(PI)，以便在多路径中选择一条路径。最佳选择策略使用一条路由，并保存备份路由信息以实现容错。中等负载均衡策略使用路由多样性来均衡网络负载。因此，路径选择策略在考虑全局动态网络性能的基础上进行了调整。我们使用OMnet模拟器对该协议进行了测试，并与一些传统方法在不同网络负载下的性能进行了比较。仿真结果表明，与其他协议相比，我们提出的协议有明显的改进。
We develop an AODV (Ad hoc On-demand Distance Vector)-based Multipath routing protocol with Preferential Path Selection Probabilities (AODVM-PPSP) for a Mobile Ad hoc Network (MANET). This protocol introduces a new method, in which an appropriate policy is decided deliberately between the best selection policy and the moderate load balancing policy, providing corresponding preferential path selection probabilities (P i) to each node for selecting a route among the multipath. The best selection policy uses one route and saves backup routes information for fault tolerance. The moderate load balancing policy uses route diversity to balance network load. So the path selection policy is adapted with consideration of the global dynamic network performance. We evaluate our protocol with Omnet simulator and compare the performance with some conventional methods under various network loads. The simulation results show that our proposed protocol has a significant improvement over the others.
