摘　　要：提出了一种分布式MANETs路由协议,该协议综合了基于DHT的应用路由协议Tapestry和网络层路由协议AODV的优点,使用随机路标算法对网络进行分簇,改进了Tapestry算法使其在分簇内节点间共享对象指针。仿真实验表明本协议可以有效避免覆盖层与物理层匹配失效的问题,在节点移动速度较快时仍能保持较高的路由查找成功率和较低的网络开销。This paper proposed a distributed MANETs routing protocol, which combining both the advantages of DHT-based protocol Tapestry and AODV, clustering the network with random landmarking, improved Tapestry to make it share object pointers between clustered nodes. Simulation experiments show that the proposed protocol could effectively avoid the mismatch problem of overlay and physical layer. It can reach a high success ratio of object search and maintain a low-cost network in spite of a quick node speed.
