摘　　要：无线双通道网络(Dual-channel network,DCN)能够有效解决码分资源浪费问题.大规模战术组网场景下,DCNs使用基于全连通子簇的分层分布式网络拓扑结构.设计了一种双通道网络分簇路由协议(Dual-channel network clustered routing protocol,DNCRP).DNCRP借鉴表驱混合路由思想,利用2跳范围邻簇ID和节点隶属信息完成基于源簇的2跳邻簇范围内簇间路由寻找,联合使用基于总簇首的拓扑信息计算和AODV路由寻找完成2跳邻簇范围外簇间路由寻找,而簇内通信因为源目的节点1跳可达则直接通信.仿真结果证明,在高业务负载和慢拓扑变化条件下,DNCRP具有优越的低时延和高吞吐量特性.Wireless dual-channel network （DCN） can solve code resource wastage problem efficiently. Under large scale tactical scenarios, DCNs employ hierarchical distributed network topology based on fully-connected network. This pa- per proposes a dual-channel network clustered routing protocol （DNCRP）. Based on the hybrid idea of proactive and on-demand routing, DNCRP uses both 2-hop-distance neighbor cluster IDs and node attribution information to search the path of inter-cluster routing within the 2-hop-distance neighbor clusters according to source cluster, and uses the combination of topology information calculation and AODV to search the path of inter-cluster routing stayed out of the 2-hop-distance neighbor clusters. In addition, In DNCRP, the source node of intra-cluster communication can directly communicate with the destination node, due to the 1 hop distance of source and destination. Simulation results demon- strate that, under the condition of high load and low mobility, DNCRP satisfies the requirement of DCN routing, and can provide a satisfactory end-to-end delay and network throughput.
