A route searching algorithm of BPLC and TWACS integrated communication

With the aim to solve the frequent network reconfiguration problem caused by link failure in the broadband powerline communication (BPLC) system, this paper inroduces the two-way power frequency automatic communication system (TWACS) into current BPLC system. And in this BPLC and TWACS integrated communication system, a TWACS signaling based routing searching algorithm is proposed, to meet the requirements of both reliability and coverage in power line network. Signaling design based on TWACS technology is described, including the initialization, operation, maintenance and reconstruction in detail. Finally, the validity and superiority of the proposed algorithm and protocol design are evaluated through simulation analysis. Simulation results show that the proposed algorithm is able to conduct network reconfiguration and reconstruction with high efficiency, low cost and better reliability.
