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 can not 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.

合理的信道选择和分配是信息物理融合系统公平路由协议设计的基础和前提。本文针对信息物理融合系统提出了一种混合无线网状网络的信道分配优化算法。设计了一种新的信道分配模型，利用贪心算法为无线网络链路选择干扰最小的信道。本文基于时空多接口和多信道分配优化算法，提出了一种基于贪心算法的联合信道分配算法。节点之间的通信被人为地划分为连续的子时间段，但不能保证节点之间的通信存在于某个时间段内。
