In this paper we investigate multi-service load balancing mechanisms in an overlay heterogeneous WiMAX/WLAN network through vertical handover. Considering the service characteristics of the overlay heterogeneous network together with the service requirements of different applications, all streaming applications are served in WiMAX while elastic applications are distributed to WiMAX and WLAN. Two load balancing mechanisms are compared which switch the elastic application with maximum (MAX) and minimum (MIN) remaining size respectively to WLAN. Simulation results indicate that MIN outperforms MAX at the cost of significantly increased number of load balancing actions. Furthermore, it is discovered that both load balancing granularity and proper integration of streaming and elastic applications in WiMAX determine the whole system performance.
