Whitepaper: TCP With Header Checksum Option for Wireless Links: Analytical Approach Towards Performance Evaluation

by Indian Institute of ScienceJan 01, 2008

Transmission Control Protocol (TCP) is a reliable, end-to-end; transport protocol widely used to access the Internet and to support applications like telnet, ftp and. TCP performs poorly in wireless mobile networks due to large bit error rates. Basically, the TCP sender responds to these losses as if they were due to congestion in the network, and reduces the congestion window unnecessarily. This paper focuses on an analytical study of this modified TCP protocol. It derives an expression for the probability of a receiver generating successful ELN, assuming a generic link layer protocol for data transfer over wireless links.
