Objectives: To study various aspects of coverage problem and various efficient sensor deployment strategies in wireless sensors networks. Methods: In this paper we have described various coverage related issues and how an efficient deployment strategy can improve the coverage depending on the application area of interest. Findings: Coverage and Connectivity are the two critical performance metrics of a Wireless Sensor Network (WSNs) which determines the Quality of Surveillance (QoS) provided by the network. Efficient deployment of sensors is one of the fundamental issues which can improve the coverage and reduces the coverage holes of the region of interest. The objective of optimal sensor deployment is to have at least one sensor such that each point of the beleaguered region is under the observable area of any of the sensor nodes. The coverage schemes based on Voronoi diagram, Delaunay triangulation and various other schemes has been elaborated. There are many unmapped issues related to coverage problem and sensors deployment that need to be explored and studied as an open research area. Improvement: This paper presents a broad overview of the different deployment strategies and various coverage problems in wireless sensor networks. We tried to create a clear platform for the neophyte researchers so that they could have an extensive idea about the relevant field of research in wireless sensor networks.
