TCP over 2.5G and 3G wireless networks

Transmission Control Protocol (TCP) by IETF is one of the most widely used transport layer protocols in Internet. Recently, much development and deployment activity has centered around GPRS, UNITS and UNIT-2000, also referred to 2.5G/3G wireless networks. However, TCP has not been designed bearing in mind wireless networks. Especially flow control features can perform less than optimally over wireless interfaces. A number of TCP optimization techniques have been studied to enhence the TCP performance for various wirless environments. This paper proposes a profile of such techniques, particularly effective for to 2.5G/3G wireless networks.
