无线传感器网络概率覆盖模型研究

Research of Probability Coverage Model in Wireless Sensor Network

针对无线传感器网络中随机部署节点的网络覆盖问题,提出一个基于正方形区域的概率覆盖模型。根据一定的覆盖期望值,在考虑网络边界影响的条件下给出所需部署的节点数。模拟实验结果表明,该模型可以在不依赖节点信息的前提下,以尽可能少的节点实现网络覆盖。

Aiming at the network coverage problem of random deployment node in Wireless Sensor Network（WSN）, this paper proposes a square region based probability coverage model. According to the coverage expectation and the impact of network boundal% it gives the number of nodes that need to be deployed. Simulation experimental results show that the model can cover the region by using least nodes without the information of these nodes.
