Speed adaptive mobile IP over wireless LAN
In this paper, the performance of MIP/WLAN at different moving speeds is evaluated on a testbed. The result shows that current MIP protocol is not suitable for rapid moving environments. Through analyzing the relationship of the performance and the moving speed and breaking down the handoff latency of MIP over WLAN, we propose a speed adaptive MIP protocol extension. In this protocol extension, a concept, handoff rate, is defined and is used to extend the MIP protocol. An evaluation of the speed adaptive MIP shows that it greatly improves the performance of MIP over WLAN in rapid moving environments. Copyright (C) 2008 John Wiley & Sons, Ltd.
