Wireless sensor node deployment method, storage medium and computing device

Abstract

The invention discloses a wireless sensor node deployment method, a storage medium and computing equipment, and the method comprises the steps: carrying out the population initialization of firefliesin a target monitoring region through employing a good point set, enabling firefly individuals to be uniformly distributed in a target region, and improving the solution space traversal of the fireflyindividuals; introducing a firefly algorithm improved by a deformation sigmoid function curve with a nonlinear exponential decline characteristic, so that the capability of searching a new high-brightness individual in a target area and the capability of searching a new high-brightness individual near a current optimal solution are kept balanced; and finally, tiny disturbance being carried out through Gaussian distribution, so that the trap of falling into precocity caused by gradual approaching of individuals to individuals with better fitness values in the later stage of firefly algorithm iteration is overcome.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, and in particular relates to a wireless sensor node deployment method, a storage medium and a computing device based on a good point set self-adaptive optimization firefly algorithm. Background technique [0002] Wireless sensor networks (WSNs) are multi-hop wireless networks composed of multiple sensor nodes and self-organized through wireless communication. Each node in the network has the ability to perceive communication, calculate and store data, and process and transmit data. Wireless sensor networks are widely used in military industry, agriculture, forestry, aerospace, structural health monitoring and other fields due to their flexible deployment and high reliability. . The target area coverage of sensor nodes is one of the indicators to measure the service quality of WSN. In order to provide a new idea for the WSN coverage optimization problem, the swarm intelligence al...
