| 摘 要： | 无线传感器网络（WSN）部署在随机区域，为达到一定随机覆盖率，需要布置大量的传感器。在实际部署中，由于传感器布置的随机性和不确定性，传感器网络随机覆盖度和传感器数量成正比。针对传感器节点高密度部署造成节点冗余等问题，通过对随机覆盖率与传感器节点数量关系分析，给出在一定覆盖率和监测半径下与传感器节点数目的关系，并在此基础上对传感器节点进行Delaunay三角剖分，分析了在实际情况下，传感器网络的连通性和覆盖性之间关系的规律，以有效监控网络的连通性。

| Abstract: | Wireless sensor network （WSN） deployed in a random area, to achieve a random coverage is necessary to arrange a large number of sensors. Since the sensor arrangement randomness and uncertainty in the actual deployment, the sensor network coverage and proportional to the number of random sensors. Therefore, the sensor nodes for high--density deployments cause node redundancy and other issues. Through random coverage and analysis of the relationship be- tween the number of sensor nodes, given the relationship between the number of sensor nodes in a certain radius of coverage and monitoring, and on this basis, the Delaunay triangulation sensor nodes, analyzed under actual conditions, sensor connectivity and coverage of the network. |
