Coverage Hole Detection in Wireless Sensor Networks
Rakesh Kumar [37] | Sakshi Dhingra
Abstract: Wireless sensor network is the area where many researchers are focusing. The emerging technology of WSN is expected to provide a broad range of applications, such as battlefield surveillance, environmental monitoring and smart space and so on. Coverage is the important quality of service which is provided by the wireless sensor network. The coverage hole problem is a fundamental issue in WSN. This problem occurs when sensor nodes are arranged randomly in the area, poor installment or nodes whose. power weeks and when the design of the network fails. This paper address the work of hole detection and healing in mobile WSNs and how reduce the redundancy in WSNs by various authors. By knowing the above issue, a modified hole detection and healing method is proposed that could remove the redundant nodes and moving the nodes that removes holes by using distributed virtual force based approach in WSNs.
