Wireless sensor networks (WSNs) have been considered as one of the fine research areas
in recent years because of vital role in numerous applications. To process the extracted data
and transmit it to the various location, a large number of nodes must be deployed in a proper
way because deployment is one of the major issues in WSNs. Hence, the minimum number
of node deployment to attain full coverage is of enormous significance for research. The
prime agenda of the presented paper is to categorize various coverage techniques into four …

Wireless sensor networks (WSNs) have gained wide attention from researchers in the last
few years because it has a vital role in countless applications. The main function of WSN is
to process extracted data and to transmit it to remote locations. A large number of sensor
nodes are deployed in the monitoring area. Therefore, deploying the minimum number of
nodes that maintain full coverage and connectivity is of immense importance for research.
Hence, coverage and connectivity issues, besides maximizing the network lifetime …
