嵌入D2D功能蜂窝网络中接入失败概率估计方法
Estimation of access failure probability in D2D underlaid cellular networks
摘要
Abstract
Device-to-Device (D2D) communication can reduce the mobile devices' energy consumption and increase the spectral efficiency in D2D underlaid cellular networks.However,D2D users will interfere with co-channel cellular users,which can lead to cellular communication access failures.There are two reasons for cellular communication access failures: D2D interference and insufficient spectrum resources.To address the absence of research on the performance of cellular services'access in D2D underlaid cellular networks,this paper defines the new services'access failure probability and handoff services'access failure probability to evaluate the effect of both D2D interference and limited resources on cellular communication access.Based on the stochastic geometry and stochastic process,a random network model is presented to estimate the access failure probabilities,which can provide guidelines for network design to ensure cellular services'access.The accuracy of the estimated access failure probability is validated through extensive simulations.关键词
