Research the optimization problems about transmission performance in tactical network. Barrage Relay Network (BRN) need to build effective routing repeatedly in the tactical group communication and produce lots of o-verhead and delay, leading to low transmission efficiency. This paper came up with a new Barrage Relay Network called C -BRN, which combines BRN with clustering algorithm. The computer simulation analysis shows that C -BRN can not only carry on the excellent performance in the tactical group communication, but also avoid the control overhead and network delay in routing reconstruction process.%研究战术网络通信传输性能优化问题.由于在战术群组通信中阻继网络(Barrage Relay Network,BRN)需要多次构建有效路由,开销和延迟大,网络传输效率不高,为提高网络路由利用率,将分簇算法引入到阻继网络中,构造了一种节点分簇的阻继网络(Clustering-BRN,C-BRN).通过仿真分析表明,C-BRN不仅继承了BRN的鲁棒性和可扩展性等性能优势,并且在战术群组通信中避免了路由重建带来的控制开销和延迟,为网络传输效率提高设计提供了依据.
