Analysis of Coverage Hole Problem in Wireless Sensor Networks

Abstract

Wireless sensor networks, coverage is a critical issue affecting the lifetime and connectivity of sensors. A hole can occur in any part of the network due to various reasons. Hence, the detection and healing of hole have become important for achieving the coverage. This paper analyses the review of various contemporary authors’ work based on different network coverage parameters. Further, a table is presented for the algorithms with the achievements and weakness involved. In this paper, simulation result analyses various models based on different parameters. Finally, the conclusion summarizes the paper with the future scope of the work.
