Abstract:
In this paper, we propose a feedback-aided irregular repetition slotted ALOHA (F-IRSA) protocol which depends on the distance between the received packet and the set of packets already recovered at the receiver. We employ feedback messages to terminate the user retransmission process, and use successive interference cancellation (SIC) for packet recovery. We evaluate the number of transmissions per user (NTU) of the proposed protocol, and show that a very small amount of feedback messages from the receiver can significantly reduce NTU. Thus, it can prolong the service life of user equipments. Simulation results show that the performance of NTU and throughput of F-IRSA protocol outperform IRSA protocol significantly.
