Multi-path TCP has recently shown great potential to take advantage of the rich path diversity in data center networks (DCN) to increase transmission throughput. However, the small flows, which take a large fraction of data center traffic, will easily get a timeout when split onto multiple paths. Moreover, the dynamic congestions and node failures in DCN will exacerbate the reorder problem of parallel...
TCP suffers from low throughput and high latency because of its expensive timeout based loss recovery mechanism in data center networks (DCNs). In this paper, we propose TCP with Adaptive Complementary Coding (TCP-ACC) to effectively address these problems. Without revising existing TCP congestion control, we first design a light-weight complementary coding scheme to avoid TCP timeout which will result...
To improve cooperative efficiency in mobile ad hoc networks, a relay-optimized cooperative MAC (RO-CMAC) protocol is proposed in this paper. In the protocol, an optimal relay is selected through two or three contention phases in case of low data rate of direct transmission from a sender to its recipient. In the first phase, all relays with the highest data rates to the sender and its recipient are...
Channel conditions on satellite communication systems are changed continuously. The Rate Compatible Punctured Turbo (RCPT) Codes Hybrid Automatic Repeat Request (HARQ) have been shown to improve reliable communications by adapting varying channel conditions. The paper discusses the throughput performance and transmission numbers of three HARQ schemes including partial incremental redundancy (partial-IR)...
