Abstract

Outage Probability of Vehicular Networks under Unreliable Backhaul

Highlights

  • Future wireless networks are expected to be more dense and heterogeneous to satisfy the growing data demand

  • Numerical results of the outage probability are studied to evaluate the impact of backhaul reliability and the number of mobile small cells on the system performance

  • The threshold of outage probability is fixed at 1 bits/s/Hz

Summary

Introduction

Future wireless networks are expected to be more dense and heterogeneous to satisfy the growing data demand. In HetNets, small cells with low power are deployed within the high power macro cell coverage area to increase gain in coverage and capacity [1] [2] [3]. In vehicular networks these small cells can be deployed on the move. To the best of the authors’ knowledge, the impact of wireless backhaul on system performance over double-Rayleigh fading channels for vehicular communications has not been studied yet. For a random variable X, FX(·) denotes its cumulative distribution function (CDF) and fX(·) denotes the corresponding probability density function (PDF). max (·) and min (·) denote the maximum and minimum of their arguments, respectively
