摘　　要：基于AODV(Ad Hoc on demand distanceVector)提出了一种新的按需多径矢量路由协议模型TRND-AODV(TreeRoot Node Disjoint Ad-Hoc On Demand distance Vector),旨在增强路由的健壮性,增强网络对拓扑变化的适应能力。通过对AODV路由协议发现过程的修改,能够在源节点和目的节点间提供多条节点分离的无环链路。仿真结果表明,该协议模型能有效地减少路由开销、加快数据包的转发速度。Based on AODV （Ad Hoc on-demand distance vector）, a novel on-demand multi-path vector muting protocol for a mobile Ad Hoc network is proposed. The protocol can provide multiple loop-free node-separated links between source nodes and destination nodes. We evaluated our protocol with OPNET simulator and compared the performances with conventional methods. We examined our protocol under conditions of various network loads and various rates of nodes. The simulation results show that the proposed protocol has significant improvement over others.
