“…As evident from the past literature, ARQ techniques have always benefitted from the utilization of FEC codes for improving their performance; obviously, the cooperation-based ARQ schemes are also eligible to employ them. For terrestrial wireless networks, the expected enhancement in performance when a cooperation-based ARQ is combined with the error correction technique of IR-HARQ, to form a cooperative hybrid ARQ, has also been verified [ 10 – 12 ].…”

“…Moreover, sensor networks have large numbers of nodes located in close proximity with each other, which makes it important to consider the effect of multiple neighbor nodes on throughput and energy efficiency when designing any cooperative protocol for UASNs. However, the previous analysis considers only single relay assisted cooperation [ 10 – 12 ]. In this paper, C-HARQ has been designed keeping in mind the presence of multiple sensor nodes in the neighborhood, which could play a significant role in improving the throughput performance.…”

Due to its efficiency, reliability and better channel and resource utilization, cooperative transmission technologies have been attractive options in underwater as well as terrestrial sensor networks. Their performance can be further improved if merged with forward error correction (FEC) techniques. In this paper, we propose and analyze a retransmission protocol named Cooperative-Hybrid Automatic Repeat reQuest (C-HARQ) for underwater acoustic sensor networks, which exploits both the reliability of cooperative ARQ (CARQ) and the efficiency of incremental redundancy-hybrid ARQ (IR-HARQ) using rate-compatible punctured convolution (RCPC) codes. Extensive Monte Carlo simulations are performed to investigate the performance of the protocol, in terms of both throughput and energy efficiency. The results clearly reveal the enhancement in performance achieved by the C-HARQ protocol, which outperforms both CARQ and conventional stop and wait ARQ (S&W ARQ). Further, using computer simulations, optimum values of various network parameters are estimated so as to extract the best performance out of the C-HARQ protocol.
