The Backup Routing Mechanism for Dual-Model Communication Network under the CSMA Protocol

To solve the problem of link interruption selection between alternate routing proxy coordinator and upper layer communication in dual-mode communication networks, this paper proposes an alternate routing mechanism based on Carrier Sense Multiple Access (CSMA) protocol. This mechanism aims to solve the problems of node congestion and resource waste caused by abnormal communication link. By introducing adaptive backoff algorithm, the data collision rate and communication delay are reduced. At the same time, the strategy of preferentially selecting terminal sites as backup routes is proposed, which further improves the transmission efficiency and stability of the network. The simulation results show that the proposed scheme effectively improves the robustness of the network, and provides strong support for the reliable communication of the power consumption information acquisition system of smart grid.
