ABSTRACT

In this paper, a WSN mountain surface coverage strategy based on particle swarm optimization(PSO) is proposed. Due to the irregular nature of 3d surface, a directional gradient sensing model is introduced to transform the coverage problem of 3d surface onto that of 2d surface, and PSO is used to optimize the location of network nodes to achieve optimal coverage. Simulation experiments verify the correctness of the coverage strategy and effectively solve the coverage problem of WSN 3d surface.
