A distributed self-healing coverage hole detection and repair scheme for mobile wireless sensor networks

The most fundamental task of the wireless sensor network (WSN) is to monitor a specified region of interest with sufficient sensor coverage. This task is jeopardized when coverage holes appear after the network's deployment. The emergence of coverage holes is unavoidable for many reasons such as sensor node energy depletion, physical damage, or external attacks. Therefore, it is important to have an ongoing mechanism for coverage maintenance...
