Now a day's, it has been a great idea of research on using Wireless Sensor Networks (WSNs) to assist in the initial deployment of sensor nodes.Hole problem in WSNs is the most fundamental Problem in WSNs.Hole means a communication gap in WSNs.Finding an optimal sensor deployment strategy that would minimize the cost, reduce the node failure and also reduce the communication overhead.Then it provides a maximum degree of area coverage with lower cost of deployment of sensor nodes, best possible communication and maintaining the network connectivity.However, it increases the quality of service in WSNs that is extremely challenging.In this article, we present various types of holes, a comparative study of various types of holes and various types of coverage holes.At the end, we proposed an Algorithm to detect hole.In this paper, we aim to give the solution of hole problems of area coverage in WSNs.
