英文摘要：

Traditional method in the optical fiber laser sensor network node deployment, the network coverage rate is low, the node energy consumption is higher, the influence of the performance of the optical fiber network and service life. Put forward a based on probabilistic sensing model of fiber laser sensor network mobile relay node deployment research methods, first of all according to the target area of coverage and energy consumption of nodes in two important indicators to build probabilistic sensing model and obtain the nodes around the perceived probability; perceived probability model increase mobile relay nodes to optimize the structure of optical fiber sensor network topology based on, by calculating the mobile relay nodes moving probability to determine the direction of movement, fiber laser sensor node deployment is complete. Experiments show that the proposed method can improve the coverage of fiber laser sensor network, save node energy consumption and prolong the service life of the network.
