Strategies of Coverage Hole Repair in Wireless Sensor Networks

With the widespread application of Wireless Sensor Networks (WSNs) in daily life, enhancing the practicality and effectiveness of WSNs has gradually become an urgent demand. The issue of repairing coverage holes in WSNs has emerged as a hot research topic. Therefore, this paper aims to categorize and organize various repair strategies to provide research insights for more scientific researchers. This paper systematically categorizes and summarizes repair strategies for coverage holes in WSNs from four aspects: Adjustment of Mobile Nodes, Network Topology Optimization, Dynamic Routing Adjustment, and Adjustment of Coverage Range. It discusses the advantages and disadvantages of these strategies and the problems they address.
