摘　　要：为使高速窄带电力线通信(HNPLC)满足智能电网的双向互动需求,结合HNPLC的底层技术,设计实现了具有低信令、低时序开销的跨层交互组网机制和具有双向互动功能且综合代价最小化的分布式按需路由机制。在实际的HNPLC网络中对面向双向互动的组网和路由机制进行性能验证。计算机仿真结果表明,所提出的路由机制比传统方法具有更快的传输速率、更好的负荷均衡性和更高的通信成功率;与树状拓扑或人工蛛网拓扑相比,采用Mesh拓扑能使双向互动HNPLC网络更具优越性。New schemes of both networking and routing for the high-speed narrowband power line communication（HNPLC）are proposed to meet the demand of bidirectional interaction in the smart grid.The networking scheme is implemented with Mesh topology adopting low cost of timing and signaling overhead by the cross-layer consideration.A distributed on-demand routing protocol with the function of bidirectional interaction is provided to minimize the integrate cost.Performance of the proposed networking and routing is evaluated in a practical HNPLC network.The simulated results show that the proposed routing scheme outperforms the traditional schemes in terms of faster network rate,better load balance and higher transmission success rate.Mesh based networking has more advantages than the tree and artificial cobweb based networking in the bidirectional and interactive HNPLC network.
