摘　　要：在无线自组织网络中,路由协议对网络的性能起着关键性作用。然而由于无线信道的不稳定性经常造成通信中断而需重建路由,使自组织网传统路由协议的效率大大降低。提出了一种应用于无线自组织网络的机会路由协议(WAOR),利用无线信道的广播特性和多径传输来增强链路的可靠性。采用网络仿真器NS2的仿真结果表明,WAOR的性能优于传统的动态源路由协议(DSR)和自组织网按需平面距离矢量路由协议(AODV)。Routing protocol has crucial impact on the network performance in wireless Ad hoc network.Communications often break off due to the instability of wireless channel,thus requiring the routing reestablishment;this would bring efficiency degradation to the traditional routing protocols of Ad hoc network.WAOR,an opportunistic routing protocol suitabe for wireless Ad hoc network,is proposed.In WAOR,packets are broadcasted among multiple paths according to some schemes,and this could efficiently improve reliability of wireless paths.Simulation results with network simulator NS2 indicate that WAOR performs better than Dynamic Source Routing（DSR） and Ad-hoc On-demand Distance Vector Routing（AODV）.
