Efficiency and fairness trade-off for TCP over UMTS-TDD

Wireless data and multimedia are rapidly becoming a dominant issue of radio communications. In this context, the support of Internet applications based on the TCP presents several open issues due to the specific nature of the wireless network segment. The aim of this work is to evaluate by a rather detailed simulation model the performance of TCP data transfer over the TD-CDMA scheme of the UMTS TDD radio interface. The distinctive point of view is exploring the limits of a relatively, simple approach, by adopting the MAC/RLC connection oriented mode of operation for bulk, loss sensitive data. Features and parameters values that optimize TCP data transfer are discussed and their benefit quantified
