【Abstract】 Traditionally, the wireless sensor network node redeployment ignored the local search of subgroup nodes, leading to low coverage rate and node connectivity. Therefore, a method of deploying wireless sensor network nodes based on SFLA was put forward. Firstly, the wireless sensor network node was initialized and SFLA was introduced. The global exchange of information was combined with the local search of the subgroup to determine the range that wireless sensors could detect. Moreover, the calculus method was used to solve irregular areas and thus to find the optimal solution. Finally, the deployment of wireless sensor network nodes was completed. Experimental results show that the proposed method has a higher coverage rate, better node connectivity, and higher node energy. This method has a better application value.更多还原
