A Novel Algorithm for Solving the Coverage Hole and the Complete Coverage Range in Wireless Sensor Networks

Based on the area problem of coverage hole and the complete coverage range in wireless sensing networks, in this paper, First, the expression of node coordinates is given; Second, the node deployment based on the united expression of the node coordinates is described. Third, an algorithm is programmed to calculate the area of coverage hole and the total coverage range. At last, the numerical example shows that given a kind of node deployment, a group of area values and ratios corresponding to the different numbers of failed nodes and simulation times can be successfully obtained.
