摘　　要：针对电力线信道中存在幅值波动很大且具有强时变特性脉冲噪声,严重影响电力载波网络通信性能的问题,分析了电力线网络拓扑结构以及电力线载波通信经典路由算法,并在此基础上提出了一种交叠分层诱导的自动路由算法(OHIA),重点验证了该算法的可行性,并给出了诱导因子传递过程、路由寻址过程以及基于预测的路由维护策略。通过NS-3仿真平台建立PLC节点模型,分别仿真蚁群算法和交叠分层诱导的PLC自动路由算法。仿真结果表明,相比蚁群算法,交叠分层诱导的自动路由算法明显改善了强时变信道环境下第一次通信成功率,并在PLC大规模组网方面取得较大进步。Aiming at the problem of impulse noise with large amplitude fluctuation and strong time-varying characteristics, which seriously affected the communication performance of power carrier network, the power line network topology and the classical routing algorithm of power line carrier communication were analyzed, and on this basis, an algorithm of overlapping hierarchical induction algorithm （OHIA） was proposed, which proved the feasibility of the algorithm and gave the inductive factor transfer algorithm, route addressing process and forecast based route mainte- nance strategy. Through the NS-3 simulation platform to establish the PLC model, respectively, ant colony algorithm and overlapping layer induced PLC automatic routing algorithm were simulated. The simulation results show that compared with the ant colony algorithm, the proposed algorithm improves the success rate of the first communication in the strong time-varying channel environment, and makes great progress in the large-scale networking of PLC.
