Recently, the integration of WiMAX and WLAN has been seen as a promising approach towards 4G.A number of wireless communication technologies are migrating towards heterogeneous overlay networks. In this paper, the authors investigate and integrate the VHO (Vertical HandOff) issues in WiMAX/WLAN networks based on best QoS (Quality of Service) for the users. Designing of VHOM to achieve proactive handoff to avoid packet loss and ping-pong effect'. Moreover, they derive evaluation algorithms to estimate the condition of both WiMAX/WLAN networks in terms of available bandwidth, relative signal strength and packet drop.
