Whitepaper: Impact of Layer 2 Behavior on TCP Performance in WLAN

by Kyushu Institute of TechnologyJan 01, 2008

This paper investigates TCP goodput performance under the criteria for handoff decisions employed in existing studies. Then, it focused on Layer 2 behavior and identified how the movement of an MN affects overall TCP performance as well as its own TCP performance. Simulation results showed that the existing technologies, which make the decision to execute a handoff based on packet loss and the change in RTT, could cause performance degradation of both one moving MN and a WLAN shared by multiple MNs.
