Synergy of Internet, wired and wireless networks is done. TCP remains the most important and most used transport protocol for non real time services such as web, email, ftp, which are basis for additional value-added or novel IP-based services. In this paper we conduct detailed analysis of the impact of the Duplicated ACK and Delayed ACK parameters on the throughput in multihop wireless scenario with incorporated loss models under traffic load provided by different TCP versions.
