Packet corruption negatively affects TCP through-puts because losses are interpreted as congestion. To enable TCP to operate effectively over wireless networks, a number of reliability techniques such as Forward Error Correction (FEC) and Automatic Repeat Request (ARQ) are used. These provide reliability at the expense of increased overheads. This study provides experimental results of a new distributed...
Comparing to wired network, there are many different characteristics in wireless environments such as higher error rate, lower bandwidth, frequent mobility and so on, which result in difficulty to guarantee qualities of service (QoS). To improve TCP performances in wireless networks, we propose a novel TCP congestion control mechanism with QoS-guaranteed cross-layer optimization that can be easily...
In this paper, we proposed a partially reliable - concurrent multipath transfer (PR-CMT) that is featured with partially reliable multi-path transmission based on the concurrent multipath transfer (CMT) and the stream control transmission protocol partial reliability extension (PR-SCTP). The proposed partially reliable transmission is realized by the "timed reliable service". Data in PR-CMT...
This paper discusses a link layer protocol that enhances performance of the Transmission Control Protocol (TCP) over a last-hop wireless network (LHWN) to make it more suitable for delivery of a live video with a short play out deadline. The presented protocol provides preference control of the transmission of video data within the network and it maximizes network goodput (the successfully transmitted...
