Wi-TCP: A TCP in Wireless Environment
Due to the strong drive towards wireless Internet access through mobile terminals, it has become necessary to carefully handle the issues in the wireless environment such as frequent handover/handoff (user mobility), temporary disconnection, burst error and fading. These characteristics of wireless environment deteriorate the performance of wireless systems sharply in terms of TCP throughput as...
متن کاملbandwidth estimation in wireless networks (tcp-bwiw): to improve tcp performance in wireless communication networks
as wireless networks with high data rate get widely deployed, improving the performance of tcp over these networks plays vital role. wireless link losses have dramatic adverse impact on tcp performance due to the difficulty in distinguishing the congestion losses from wireless link losses. we first, studied the various existing bandwidth estimation algorithms over the wireless networks. in this...
متن کاملMultipath TCP in Lossy Wireless Environment
Random loss in wireless ad hoc nets derives from two main causes: lossy wireless channels and node mobility. Breakage and loss can significantly degrade the performance of network protocols, especially TCP. Recently, several schemes have been proposed to protect TCP from mobility induced link breaks by freezing TCP state when a link break is detected. TCP freeze however does not help with high ...
متن کاملStudy of the TCP Unfairness in a Wireless Environment
In this paper we analyze the TCP performance degradation introduced by a wireless media having transmission errors and the capability of the following mechanisms to correct it (i) improvements over the TCP Reno release (SACK, New-Reno and FACK); (ii) improvements over the classical “tail dropping” mechanism used by routers (RED and ECN); and (iii) a TCP implementation based on the usage of ECN ...
متن کاملWe TCP-AP: Wireless Enhanced TCP-AP
Congestion control in wireless networks is strongly dependent on the dynamics and instability of wireless links. It is known that TCP experiences serious performance degradation problems in wireless networks. New approaches based on TCP try to overcome these problems but, although their performance is increased, they incur in congestion control errors, since they do not evaluate accurately the ...
