Impact of Multiple TCP Flows in TCP-AP with LRED over Multihop Wireless Networks and MANETs
Transmission Control Protocol (TCP) was designed to provide reliable end-to-end delivery of data over unreliable networks. In practice, most TCP deployments have been carefully designed in the context of wired networks. Ignoring the properties of wireless and ad-hoc networks can lead to TCP implementations with poor performance. In these networks, however packet losses occur more often due to unreliable links than due to congestion. When using TCP over wireless links, each packet loss on the wireless link results in congestion control measures being invoked at the source. This causes severe performance degradation. If there is any packet loss in wireless networks, then the reason for that has to be found out. If there is congestion, then only congestion control mechanism has to be applied.
