TCP-UB: A New Congestion Aware Transmission Control Protocol Variant

Transmission Control Protocol (TCP) is a connection oriented protocol for several types of distributed applications. TCP is reliable particularly for traditional fixed networks. With emergence of faster wireless networks, TCP has been performing poorly in its original format. The performance of TCP is affected due to assorted factors including congestion window, maximum packet size, retry limit, recovery mechanism, backup mechanism and mobility. To overcome deficiency of original TCP, several modifications have been introduced to improve network quality. The mobility is a major hurdle in degrading the performance of mobile wireless networks.
