  Abstract

In this paper, we explain the development procedure for a WLAN (IEEE 802.11b Wireless Lan) handoff simulator using OPNET Modeler 90 and analyze the handoff performance when TCP and UDP traffic is applied Because the BSS (Basic Service Set) is set only once at the beginning of a simulation in WLAN model supported by OPNET Modeler 9 0, the discontinuation of the communication between MS (MobIle Station) and AP (Access Point) is occurred by the migration of the MS from one BSS to another We implement a handoff simulator based on this WLAN model and analyze handoff performance in various scenarios Also, we propose a new handoff algorithm which prevents TCP timeout by analyzing the problems of the handoff using the simulator.
