In Wireless Sensor Networks (WSNs), the problem of network coverage ratio is directly related to the performance and efficiency of monitoring quality in the network and is taken an important issue for researchers. This paper analyzes the factors which will cause the impact of irregular sensing range of sensors and presents a method to detect sensing coverage hole. First, according to the property of intersection points in Optimal Geographic Density Control (OGDC), the method can calculate the location of the intersection points. Second, on the basis of two-stage grouping model, the intersection points will be divided into several groups.
