Cluster-based Wireless Sensor Network Deployment for Lunar Exploration

Recently, exploring the moon has attracted great interest. To monitor the lunar environment, wireless sensors can be scattered from the prober to the lunar surface to ensure uniform coverage of the target area. Network deployment is critical for wireless sensor networks (WSNs) because it determines the coverage and connectivity of WSNs. However, due to node damage, location deviations, and sink node failures, network deployment is challenging to achieve coverage and connectivity requirements. In this paper, we study the clusterbased WSN deployment scheme for lunar exploration, which consists of four phases, prober separation, cluster deployment, cluster landing, and networking. To meet the requirements of coverage and connectivity, a positive n-edge cross deployment method is proposed, and its connectivity and adaptability are analyzed. The simulation results show the effectiveness of the proposed method in terms of coverage and connectivity.
