摘　　要：在分组无线网的路由协议中,传统路由协议在恶意节点数目较多时网络吞吐量较低,因此提出一种分组无线网缠绕多路径数据路由协议,利用获取的源节点数量信息与位置信息进行路由发现;根据路由发现结果建立从汇聚节点至源节点之间的路径,从而建立缠绕多径路由;对缠绕多径路由进行建簇与重构;进行支路径数优化,从而实现分组无线网缠绕多路径数据路由协议的构建。为了验证上述路由协议的网络吞吐量,将路由协议与基于链路状态的主动式多路径路由协议、基于动态源的按需式多路径路由协议、基于距离矢量的混合式多路径路由协议进行对比,上述四种路由协议在恶意节点数目为30时的网络吞吐量分别为69.5%、33.5%、23.6%、4.2%,通过比较可知,新提出的路由协议的网络吞吐量最高,证明了新路由协议的性能。In traditional routing protocol of packet radio network, the throughput is low when the number of malicious nodes is large. Therefore, this article proposed a braided multipath data routing protocol in packet wireless network. Firstly, the quantity information and location information of source nodes were used to discover the route. Based on the result of route discovery, the path from the aggregation node to the source node was established, and then the braided multipath route was built. Secondly, the braided multipath route was clustered and reconstructed, so that the braided multipath data routing protocol of packet radio network could be constructed. In order to verify the network throughput of routing protocol, the above routing protocol was compared with the active multi-path routing protocol based on link state, the on-demand multi-path routing protocol based on dynamic source, and the hybrid multi-path routing protocol based on distance vector. The network throughput of four routing protocols is 69.5%, 33.5%, 23.6%, 4.2% respectively when the number of malicious nodes is thirty. Comparison results show that the network throughput of the proposed routing protocol is the highest.
