摘要
对低压电力线载波通信路由器的优化设计,可以有效提高通信路由可靠性。对载波通信路由器的设计,需要应用蚁群算法进行路径寻优,建立网关节点与网络内任意节点通信的最优路径。传统方法结合了变异遗传算法、蚁群算法等几种智能算法,但没有建立节点通信的最优路径,导致路由器设计效果不理想。提出基于分簇蛛网的路由算法。首先介绍了低压电力线的网络拓扑及其组网的必要性;然后描述了传统非交叠分簇算法和人工蛛网拓扑,详细阐述了分簇蛛网组网方法并采用此方法对低压电力线通信网络进行组网;应用蚁群算法进行路径寻优,建立网关节点与网络内任意节点通信的最优路径。仿真就算法的迭代次数的路径时延、丢包率和跳数进行对比分析,结果表明,基于分簇蛛网组网的蚁群路由算法提高了算法效率,提升了通信的可靠性,具有一定的实用意义。
In this paper, we propose a routing algorithm based on clustering cobweb. Firstly, necessity of network topology and networking of low - voltage electric flux line were introduced. Then, traditional non - overlapping cluste- ring algorithm and artificial cobweb topology were described. The method of clustering spider networking was expoun- ded in detail. This method was used in communication networking of low - voltage power line. Moreover, ant colony algorithm was used for path optimization and optimal path of communication between gateway node and any network node. Finally, comparative analysis was carried out on path delay, packet loss rate and hop count of iterations based on simulation. Following conclusion can be drawn from experimental results. The ant colony routing algorithm based on clustering cobweb networking improves the algorithm efficiency and communication reliability. It has certain prac- tical significance.
