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。
無線傳感器網絡(WSN )部署在隨機區域,為達到一定隨機覆蓋率,需要佈置大量的傳感器。在實際部署中,由于傳感器佈置的隨機性和不確定性,傳感器網絡隨機覆蓋度和傳感器數量成正比。針對傳感器節點高密度部署造成節點冗餘等問題,通過對隨機覆蓋率與傳感器節點數量關繫分析,給齣在一定覆蓋率和鑑測半徑下與傳感器節點數目的關繫,併在此基礎上對傳感器節點進行Delaunay三角剖分,分析瞭在實際情況下,傳感器網絡的連通性和覆蓋性之間關繫的規律,以有效鑑控網絡的連通性。

Wireless sensor network (WSN) deployed in a random area ,to achieve a random coverage is necessary to ar-range 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-densi-ty 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 cover-age and monitoring ,and on this basis ,the Delaunay triangulation sensor nodes ,analyzed under actual conditions ,sensor connectivity and coverage of the network .
