摘要

This article proposes a method for delay elimination of transmission signal during wireless network communication based on ant colony algorithm.Firstly,the optimal quantity of network cluster is worked out according to wireless network model,and the size of the cluster is controlled,then energy consumed by communication node in any acquisition cycle of monitoring data in cluster is worked out.Moreover,the real communication radius of wireless network node is confirmed according to node density of wireless network,and ant colony algorithm is used to carry out path search after election of cluster head.The multi-hop routing with minimum cost from cluster head to aggregation node is searched.Thus,communication delay of wireless network further is eliminated.Simulation results show that the method can effectively improve communication efficiency and eliminate communication delay.%对无线网络通信传输信号延迟消除方法的研究,能够有效保证网络的正常稳定通信.对传输信号过程延迟的消除处理,需要先进行路径搜索,搜索汇聚节点代价最小的多跳路由,完成传输信号延迟的消除.传统方法先优化网络各协作链路能效,为通信终端进行中继节点分配,但忽略了对多跳路由的搜索,导致对延迟的消除效果不够理想.提出基于蚁群算法的无线网络通信过程传输信号延迟消除方法.依据无线网络模型计算出最优网络分簇数量,控制无线网络分簇的大小,计算出簇内通信节点在任意监控数据采集周期内消耗的能量,依据无线网络节点密度确定无线网络节点的实际通信半径.采用蚁群算法在簇首选举后进行路径搜索,搜索从每个簇首到汇聚节点代价最小的多跳路由,从而进一步消除无线网络通信延迟.实验结果表明,所提方法能够有效提高通信效率,消除通信延迟效果较好.
