Abstract
The application discloses a coverage hole detection method and device, and belongs to the field of mobile sensor networks. The method comprises the following steps: obtaining a target node; determining a neighbor node of the target node according to the target node; creating a detection area according to the target node and the neighbor node, wherein only one node exists in the detection area; calculating a first distance relationship between the target node and a corresponding vertex of the detection area where the target node is located; and detecting whether a coverage hole exists in the detection area according to the first distance relationship. Thus, the application creates a detection area through a target node and a neighbor node, and then detects whether a coverage hole exists in the detection area according to the distance between the target node and the vertex of the detection area where the target node is located. In this way, the network coverage problem is converted into a local coverage problem of each node, the coverage condition in the whole area is determined by identifying the local coverage hole, and the detection reliability is improved.
