The desired characteristic of next generation wireless communication is convergence of various heterogeneous technologies. By integrating heterogeneous technologies user will be provided high data rates, good service and connectivity. In this paper, the authors consider the integration of Wireless Local Area Network (WLAN) in 3G network. They evaluate performance of two Vertical HandOff (VHO) algorithms for an integrated 3G and WLAN network. The number of handoffs and decision delay are estimated as the Mobile Terminal (MT) moves from the center of 3G network Base Station (BS) towards the AP (Access Point) of WLAN with hysteresis and dwell timer approaches.
