| 摘 要： | 针对多跳无线网络中机会路由的副本传输问题，提出一种新的机会路由协议。提出的策略不再简单采用单跳广播的方式转发数据，而是通过节点间的距离确定转发开销，再让数据包携带下一跳候选节点信息并根据候选节点的ACK选择下一跳节点，从而保证了每个数据包只有一个候选节点进行转发。仿真结果显示，提出的方案能减少不必要的传输行为，有效改善了网络吞吐率。

| Abstract: | A novel protocol of duplicate elimination in opportunistic routing was introduced. At first we decide the priority of candidate nodes by computing the distance of candidate node among present node and destination node. The protocol allows each node to control relay transmissions of its next hop candidate nodes using information piggybacked on packets. The protocol guarantees that for each packet, only one candidate node that correctly receives the packet can deliver the packet. Simulation results show that the protocol achieves higher throughput than existing opportunistic routing protocols by reducing duplicate packets. |
