摘　　要：针对窄带无线自组网络环境,设计了一种基于WRP的改进路由算法。该路由算法沿用WRP的倒数第二跳节点避免环路现象,特别是采用了报文中携带校验值取代更新消息的序列号、ACK标志等复杂操作,并提出简化的HELLO报文来维护与邻居节点的连通性。根据设定的窄带无线网络参数配置,使用OPNET仿真工具对该路由协议进行了仿真和评估。An improved routing algorithm based on WRP was designed according to narrow-band wireless network. The improved algorithm keeps the penult node in WRP to avoid the loop. Especially, it carries the check value in the packets to replace the complex operations such as series number and ACK flag and uses the simple HELLO message to maintain the connectivity with the neighbor nodes. According to the parameter configurations of narrow-band wireless network, OPNET is used to simulate and evaluate the improved routing algorithm.
