Analysis of an Automatic Repeat Request Scheme Addressing Long Delay Channels

Abstract

This paper proposes a variation to the classic implementation of Automatic Repeat reQuest (ARQ

Analysis of Age of Information Under SR ARQ

“…In this latter case, one ought to check how retransmissions can be interleaved with regular transmissions. To achieve timely status updates, in the case of sporadic generation, the source can send more replicas of the same data to proactively counteract the erasures [29]. This can be an interesting extension that is left for future work.…”

“…This serves to evaluate ARQ for what concerns timely status updates [17], and paves the road to deriving guidelines for deeper studies about various (hybrid) ARQ types [16], [18]. An interesting extension would be toward advanced ARQ schemes that take advantage of correlation to adapt the ARQ transmission [29]. One can also think of developing an ageaware ARQ scheme, in the same spirit of what done for transmission protocols at different layers [6], [28], which appears as an interesting yet challenging future work.…”

The Underwater Selective Repeat Error Control Protocol for Multiuser Acoustic Networks: Design and Parameter Optimization

“…The use of some form of TDD to support multiple packet transmissions within a single RTT has also been considered in [12]- [14]. In [12], the authors propose to share the RTT equally between two communicating nodes, so that they may transfer an equal number of packets.…”

“…Moreover, if the network is randomly deployed, it is suboptimal to choose the same window size for all nodes, as the RTT is generally different for different pairs of nodes. Finally, the protocol in [14] is designed to reduce the packet delivery delay over a single link, not in multiuser scenarios.…”
