Abstract

Reasonable channel selection and allocation is the basis and premise of fair routing protocol design in information physical fusion system. In this paper, a channel allocation optimization algorithm for hybrid wireless mesh networks is proposed for the information physical fusion system. A new channel allocation model is designed, which uses greedy algorithm to select the channel with the least interference for the wireless network link. Based on the spatiotemporal multi interface and multi-channel allocation optimization algorithm, a joint channel allocation algorithm based on greedy algorithm is proposed in this paper. The communication between nodes is artificially divided into continuous sub time periods, but the communication between nodes cannot be guaranteed to exist in a certain period of time. The communication lines between nodes can be determined to avoid the shortcoming because the shortest path is used as the index to allocate the communication path.
