Review on Deployment, Coverage and Connectivity in Wireless Sensor Networks

Recently wireless sensor networks (WSNs) have received extensive attention from the researchers’ community due to their vital role in diverse applications. Both the sensing coverage and networks connectivity are the prime issues that have a significant impact on WSNs performance. Therefore, the deployment of minimal nodes while ensuring both coverage and connectivity is of immense importance. This paper classifies different coverage techniques i.e., grid-based, force-based, and computational geometry-based with a detailed analysis of their merits and demerits. Moreover, different sensing models are discussed for a better perception of concepts. Finally, we signify the major findings and open research problems in this area.
