Performance Analysis of Heterogeneous Network Using Relay Diversity in High-Speed Vehicular Communication


In the high-speed vehicular scenario, mobile users suffer from high Vehicle Penetration Loss (VPL) and large doppler spread. Due to this, signal strength fluctuates rapidly at both mobile and base station (BS) end. This signal strength fluctuation results in frequent handovers and a decrease in energy efficiency. Relay is one of the important technologies to overcome these issues. Homogeneous network models using fixed and moving relays (MRs) have been proposed in the past to eliminate the effect of VPL and minimize the frequent handover by group handover. A heterogeneous network (HetNet) model using one MR has been proposed for downlink communication in the past. In this paper, we propose the HetNet model using two MR for downlink communication. We derive the coverage probability and analyze the coverage distance and per-user capacity for a cooperative network. We show that coverage probability, coverage distance and per-user capacity increase by using two MRs for the cooperative network, which is better than the one MR HetNet model for downlink communication.This result will be helpful and provide a choice in deploying MR in the next-generation network. Monte Carlo simulation is used to verify the result obtained from the analytical analysis.
