“…A hybrid version is also proposed that switches automatically between explicit and implicit acknowledgment, in order to improve energy consumption or latency performance. An improved multihop scheme is also presented in [7], where the authors suggest to segment packets so that the transmission time is shorter than the propagation delay. This enables each node to interlace the transmission of its own packets so that collisions with other messages are avoided.…”

“…Note that [7,13,14] focus on a network scenario, whereas our approach considers a point-to-point transmission. However, techniques like the multihop packet superposition strategy pointed out in [7], can be implemented independently to support multihop, using our ARQ strategy for error control.…”

“…However, techniques like the multihop packet superposition strategy pointed out in [7], can be implemented independently to support multihop, using our ARQ strategy for error control. Finally, we remark that our proposal can be viewed as a form of Hybrid ARQ (HARQ), due to the incremental redundancy of retransmissions, though achieved with a relatively simple repetition code.…”

“…However, the data transmission protocols based on traditional acknowledgments, for example, ARQ, are not suitable for UWASN [4][5][6] because their acknowledgment packets not only prolong the transmission delay but also waste lots of limited bandwidth. Therefore, to reduce the bandwidth waste and transmission delay, caused by acknowledgment packets, without reducing data transmission reliability, some improved ARQ-based protocols [6][7][8][9] use data packets as implicit acknowledgments; some protocols [10][11][12][13][14], such as segmented data reliable transport (SDRT) [12,13], NCRF (network coding [14] in rateless fashion) [15], and NCIA (network coding with implicit acknowledgment) [15], send coded packets in burst, which only needs a acknowledgment packet; some protocols, such as ADELIN (adaptive reliable transport) [16,17], VBF-NC (vector-based forwarding-network coding) [18] and MPNC (multiple path and network coding) [19], guarantee transmission reliability only by sending enough coed packets.…”

MPNC (multiple path and network coding) is proposed as a reliable transport protocol for UWASN (underwater acoustic sensor network). In MPNC, after three disjoint paths being established, two groups of packets (A and B), coded by network coding, are transmitted over the two side paths respectively, and another group of packets C = A ⊕ B are transmitted over the middle path. That is, any two paths can work together as a redundant path for another path, and the reliable transmission of one packet can be guaranteed by 1.5 packets. In order to reduce the number of redundant packets without affecting the transmission reliability, the packets of group C are coded further at special ratio by network coding as shareable redundant packets according to the link error, and a reliable transport protocol TPNC (twin path and network coding) based on two paths and network coding is proposed in this paper. In TPNC, after two disjoint paths, called twin paths, being established, two groups of packets (A and B), coded by network coding, are transmitted with their own shareable redundant packets over the two paths respectively to guarantee the data packet transmission reliability. The results of simulations show that, compared with MPNC, TPNC can acquire similar data delivery ratio with lower energy consumption.

“…Recent studies on this subject have analyzed ARQ schemes in detail [6], [7]. Another important field of application where investigations of ARQ techniques can be found is that of underwater acoustic communication [8], [9]. Underwater channels are highly variable and noisy, so the design of good error control mechanisms is key.…”

Modern communication systems require effective error control techniques for wireless links. This problem is still relevant in many applications involving recently developed IEEE standards such as 802.16, or sensors for environmental monitoring in extreme conditions. A notable example is also underwater communication with acoustic transmission, where long delays may be present. Usually, such studies assume the availability of an error-free feedback channels which is used to perform retransmission requests in an ARQ fashion. This paper discusses the performance of the Selective Repeat ARQ scheme in terms of packet delay when the feedback that is sent back at the transmitter's side can be erroneous. A non instantaneous noisy feedback and a Bernoulli arrival process, for different traffic intensities, are considered. The system is modeled through Discrete Time Markov Chains, including the channel and the ARQ state. The system equations are derived and solved, and the impact of erroneous feedback is quantified. With respect to other similar contributions, the proposed approach presents the advantage of being directly implementable in any analysis using Markov chains to evaluate the system properties, instead of dedicated models. It can therefore be extended to a plethora of different scenarios, including different channel models and also including FEC features so as to obtain a Hybrid ARQ scheme.Index Terms-Queueing analysis, automatic repeat request, Markov processes, error analysis.
