A main challenge in deploying wireless sensor networks (WSNs) is determining the minimum quantity of sensor nodes required to fully cover the region of interest while avoiding coverage holes. This study proposes a method to compute the number of nodes needed to monitor a circular region and a distributed control strategy based on circular formations to move dynamic agents to their desired positions. The method addresses the coverage problem, ensuring that each point in the monitored region is detected without losing connectivity. In addition, the study compares this approach with a sensor node allocation method based on Voronoi diagrams, highlighting the need for an algorithm that computes the desired positions of the agents to provide guaranteed flawless coverage; the proposed method achieves this by obtaining the desired final positions. The hybrid WSN architecture, together with the proposed method, achieves full coverage efficiently and better utilizes the detection circumference of sensors compared to traditional rectangular monitoring regions.
部署无线传感器网络（WSN）的一个主要挑战是确定在避免覆盖空洞的同时完全覆盖感兴趣区域所需的最少传感器节点数量。本研究提出了一种计算监测圆形区域所需节点数量的方法，以及一种基于圆形编队的分布式控制策略，用于将动态智能体移动到其期望位置。该方法解决了覆盖问题，确保监测区域内的每个点都能被检测到且不会失去连通性。此外，该研究将此方法与基于Voronoi图的传感器节点分配方法进行了比较，强调了需要一种算法来计算智能体的期望位置以提供有保证的完美覆盖；所提出的方法通过获取期望的最终位置实现了这一点。与传统的矩形监测区域相比，混合WSN架构与所提出的方法一起能够高效地实现完全覆盖，并更好地利用传感器的检测周长。
