Mobile IP throughput studies on a wireless LAN

The evolution of TCP has been primarily geared to support wired networks. With the increased usage and popularity of wireless networks, it is prudent to examine the effect of these modifications on wireless data transfers. This project studies the effect of some of the different flavors of TCP on the throughput of FTP data to a Mobile node. The Mobile IP protocol is the mobility mechanism used in this simulation. The NS2 simulator is programmed to use a wired-cum-wireless network topology. Many variants of TCP are used for the simulation and the data transferred and signaling traffic generated are recorded. Two base stations act as agents for the mobile node. It was shown that delayed acknowledgments offered the best throughput in the simulation whereas the Vegas implementation of rep exhibited the least.
