TCP over 3G links: Problems and Solutions

Abstract

This review paper presents analytical information regarding the transfer of TCP data flows on paths towards interconnected wireless systems, with emphasis on 3G cellular networks. The focus is on protocol modifications in face of problems arising from terminal mobility and wireless transmission. The objective of this paper is not to present an exhaustive review of the literature, but to filter out the causes of poor TCP performance in such systems and give a rationalized view of measures that can be taken against them.
