An Adaptive Communication Routing Algorithm in Dual-mode Heterogeneous Field Network of Power Distribution Grid Based on RPL Protocol

The power distribution field network is used mainly in the power distribution grid to complete the last mile communication tasks. In order to improve the connection rate and transmission rate between the nodes of the network, a dual-mode heterogeneous hybrid power distribution field network with micro-power wireless communication and high-speed power broadband carrier communication capabilities is designed in this paper. First, the topological structure, the networking process and network maintenance mechanism of the network are discussed. Secondly, the minimum communication delay of the route is used as the optimization objective function, and a metric routing algorithm based on RPL protocol is proposed. Finally, the field network is used to the power distribution information collection system, and the performance of the network is tested by simulation and in laboratory. The test results show that the proposed algorithm has higher communication efficiency and meets the networking needs of dual-mode field network, and the dual-mode field network increases the copying rate and shortens the copying time comparing the single-mode field network.
