摘要：Recently, there has been great interest in the community over heterogeneous wireless networks in order to support services with high quality. The integration of Wimax and Wi-Fi technologies in communication systems such as Voice ,FTP ,Video conducted heterogeneous system reveal that the proposed network selection technique can effectively decide the optimum network through making trade-offs among network condition, user preference while avoiding frequent handoffs. We identify vertical handover decision algorithm suitable for multimode mobile devices based on the Analytic Hierarchy Process (AHP) and evaluates its performance through simulation by Opnet. This paper gives a comparative analysis of two queuing systems FIFO and WFQ by showing the advantages of using suitable weight which was calculated by AHP. The simulation results show that WFQ technique has a superior quality than FIFO. It could be opportunity to network designers and suppliers are providing the resources to servers more efficient use.
