Modeling and performance of TCP in a MC-CDMA system for 4G communications

Abstract

Market research finds that mobile commerce for 4G wireless systems will be dominated by basic human communication such as messaging, voice, and video communication. Because of its typically large bandwidth requirements, broadband communication is expected to emerge as the dominant type of traffic in 4G wireless systems. In this paper a new TCP based Multicarrier access technique named MC-CDMA for mitigating 4G requirements is proposed. This paper also presents analytical information regarding the transfer of TCP data flows on paths towards interconnected wireless systems, with emphasis on 4G cellular networks. The focus is on protocol modifications in face of problems arising from terminal mobility and wireless transmission. We advocate the use of TCP as the transport layer protocol for high-speed data in a Multi-Carrier CDMA (MC-CDMA) system for 4G wireless communications.
