Research on Optimal Design of Wireless Sensor Network with Particle Swarm Optimization and Improved Firefly Algorithm

Since wireless sensor network coverage belongs to the category of combinatorial optimization, to improve its coverage in the case of a limited number of nodes, we introduced and improved the PGSO hybrid algorithm. In this paper, the utilization rate of nodes and the adequate coverage of the network are first taken as the optimization goals, and we established the corresponding mathematical model. We carried out the simulation experiments under the condition of a certain number of nodes, and the coverage of the proposed hybrid algorithm is optimal. Compared to other algorithms, the convergence speed and coverage rate are improved. The first part of the article briefly describes the primary use of hybrid algorithms, and the second part models and compares the four algorithms.
