Path Selection for Hybrid Fiber Communication/Sensing Network

It is very important to choose the optimal transmission path in the transmission process of fiber network. It can not only improve the ability of fiber sensing and communication, but also has great significance for the improvement of communication efficiency. This paper proposes an intelligent path selection method, which can obtain all path state information between target nodes, and then select the optimal path. A path is made up of links and nodes. Firstly, a fuzzy logic system with link failure judgment ability is constructed based on the network topology and sensing capability parameters to obtain the failure probability of each link. The parameters of link failure probability, path length, path hops and path failure probability are successively overlaid and selected step by step. Finally, the optimal transmission path between the initial nodes is selected.
