Node deployment optimization is one of the application points of wireless sensor networks (WSN), and it is also a hot topic that scholars have studied in recent years. Aiming at the problems that exist in WSN node deployment, such as uneven distribution of nodes and incomplete coverage, this paper proposes an optimization method for WSN node deployment based on ant-lion optimization algorithm. Firstly, this paper establishes a mathematical model to cover the target area with WSN nodes. Then, the optimization problem of node deployment is transformed into the problem of finding the maximum value of the function. Finally, the ALO algorithm is used to obtain the optimal solution of node deployment. The experimental results show this method works well in optimizing the deployment location of WSN nodes, and can increase the overall network coverage rate.
