A Novel CARQ Algorithm for TDMA-Based Single Source Single Relay Wireless Networks

Abstract

An efficient Single Source Single Relay Cooperative Automatic Repeat Request (CARQ) protocol for TDMA-based High Delay Wireless Networks is proposed in this paper, which enables both of the Source and the Relay to retransmit packets to the Destination based on the special nature of TDMA-based time frame structure, and increases the successful transmission probability of a packet from the Source to the Delay using the high delay between the Source and the Relay.. By means of comparison of the system throughput between the two ARQ algorithms (the traditional and the proposed algorithms), we proved that the proposed protocol gave a better performance in poor channel conditions.
