Abstract

In this paper, we aim to determine the multi-hop route between a Device-To-Device (D2D) source-destination pair that maximizes the end-To-end throughput, under stochastic interference constraints imposed by the cellular network and a target SINR constraint at the destination. We determine the maximum allowed D2D transmit powers from the interference constraints and propose a throughput-optimal routing algorithm under a target SINR constraint at the D2D receivers. Also, using elementary queuing theoretic analysis, we derive closed form expressions for throughput and delay under a sequential link activation scheme. Our simulation results show that consideration of channel statistics to determine the optimal route gives higher end-To-end data rates compared to routing based on the path loss only, and highlights the advantages of using a multi-hop route over direct link communication.
