信道随机性对传感器网络连续渗流密度的影响
Impact of channel randomness to critical density of wireless sensor networks
摘要
Abstract
In order to guarantee sensing coverage and connectivity in wireless sensor networks,exploring the influence of criti-cal density to the network coverage and connectivity,this paper proposed a novel improved Gilbert sensing model (IGSM)to analyze the impact of randomness channel to the critical density λc .The IGSMcombined the characteristics of spatial distribu-tion of sensors and the transmit channels,through the dependencies of equivalent sensing radius and continuum percolation fi-lling factor,IGSMrepresented the influences of channel randomness to the critical density of the sensor networks.Simulation results show that in random transmit channel,the critical density λc decreases as the equivalent sensing radius increases,as well as the connectivity of the network increases.关键词
