The coverage hole problem in Wireless Sensor Networks (WSNs) is one of the most important problem. The data has to be communicated through the base station that every sensor node have to be communicated to the adjacent nodes within its communication area. The level of network connectivity is used to detect the coverage hole problem. The proposed fuzzy enabled coverage hole detection methodology is used to identify the coverage hole in the network. The communication links among the sensor nodes are maintained by the path construction. The adjacent nodes are identified based on the energy level for enhanced transmission. Fuzzy rules are constructed with the parameters of Energy, Communication with adjacent nodes and network coverage with the coverage hole is detected as the output of these rules. The experimental results show that the proposed methodology has improved performance for detecting the coverage hole with various parameters.
