摘　　要：提出了一种混合式的路由协议AODV-DFR,它不仅具有先验式及反应式路由协议的特点,而且还融入了某些具有地理位置辅助的路由协议的特性。在路由失败的情况下,AODV-DFR能在断点立刻进行方向转发,快速找到合适的下一跳节点,建立新的路由。大量的仿真实验证明AODV-DFR路由协议对网络性能有较大的提高。This paper proposed ahybrid solution called AODV-DFR. AODV-DFR not only combined proaetive and reactive routing features, but also borrowed from geo-routing the concept of greedy forwarding. If conventional predecessor forwarding failed, direction forwarding was used to find a back up path to rebuild routing quickly. Extensive simulations show that AODV- DFR can significantly improve the network performance.
