[0095] V={a, b, c, d, e, f}, E={(a, b), (b, c), (c, d), (c, e), (e, f)}, The effect is as Figure 4 shown;
[0096] (2). After obtaining the geometric graph, perform a depth-first search on it, calculate the set of other vertices that can be reached from a certain fixed vertex, and finally obtain unreachable nodes. If there are unreachable nodes, use the highlighted The form is displayed, go back to step 204 for interaction design, until the deployment is completed.
[0097] Designers also need to verify the coverage of deployed WSNs in real time. Assuming that the coverage target is a building in a cell, it can be verified through the following scheme. The steps are as follows:
[0098] (1) Let the coverage of each sensor i be Σ i , there are n sensors in total, find the sum of the coverage of all sensors, that is, ∑=∑ 1 ∪∑ 2 ∪…∪∑ n ;Where i=1, 2, 3...n;
[0099] (2) Let the coverage of each building j be Φ j , there are m buildings in total, then the total coverage...
