Abstract

The invention relates to a wireless optical fiber sensor network deployment method based on particle swarm optimization. The method comprises the following steps of: establishing a bottom layer network deployment optimization model specific to the aim of minimizing the energy consumption of an optical fiber sensor node and bottom layer network cost, and solving by adopting multi-target particle swarm optimization based on a discrete binary system to obtain a bottom layer network deployment scheme and realize distributed sensing of a monitored area; and establishing an upper layer network deployment optimization model on the basic of the bottom layer network deployment scheme specific to the aim of minimizing upper layer network cost under the constraining action of upper layer network full communication, designing a fitness function for increasing particle difference, and solving by adopting particle swarm optimization based on simulated annealing to obtain an upper layer network deployment scheme and realize multiple hop transmission of sensing data. Due to the adoption of the method, the energy consumption of the optical fiber sensor node can be lowered, the energy consumption of management nodes is balanced, the network life is prolonged, the quantity of deployed routing nodes and management nodes can be reduced on the premise of ensuring full network communication, and network cost is reduced.
