异构无线传感器网络中覆盖度和连通度的研究

覆盖度和连通度研究是无线传感器网络中的关键问题。以往研究背景为同构无线传感器网络,这样可以简化问题,但随着问题的深入,不得不考虑异构节点覆盖。系统地对异构无线传感器网络进行了分类,提出了感知异构和通信异构结合的无线传感器网络下的异构节点感知模型,其次分析了两类异构节点之间的覆盖度的计算,最后分析了异构网络的单连通和重连通。此外实现了大量的仿真实验,得出了节点数量和单连通、重连通的概率曲线。

Research on Multiple Coverage and Connectivity for Wireless Sensor Network

Coverage and connectivity are the key research questions in wireless sensor networks.Previous research background is homogeneous wireless sensor networks,which can simplify problem.But along with the depth of the problem,we have to consider covering with heterogeneous node.Firstly,we classify the heterogeneous wireless sensor networks systematically,and put forward heterogeneous node model under the combinition of sense heterogeneity and communications heterogeneity.Secondly,we analyze the coverage calculation under two kinds of heterogeneous nodes.Thirdly,we analyze the simply connectivity and re-connectivity.Finally,we do a lot simulation experiments,and obtain the probability curve between the number of nodes and simply connectivity、re-connectivity.
