Abstract

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.

Highlights

Today, advances in wireless communication technologies are driving the evolution toward ubiquitous and seamless service delivery across wireless systems
Wimax is taken a relevant role in reaching the goal of realizing a full-service network all over urban and suburban area
The integration of Wimax and Wi-Fi technologies in communication systems requires the framework of intelligent vertical handoff decision algorithms to enable mobile users to seamlessly switch network access and experience uninterrupted service continuity anywhere and anytime by maintaining certain properties, mainly in terms of Quality of Service (QoS)

Summary

Introduction

Advances in wireless communication technologies are driving the evolution toward ubiquitous and seamless service delivery across wireless systems. End users will access services via several existing access technologies such as General Packet Radio Service (GPRS), wireless local area network (WLAN), and Worldwide Interoperability for Microwave Access (Wimax). Wimax is taken a relevant role in reaching the goal of realizing a full-service network all over urban and suburban area. The wireless local area networks (WLAN) is widely used for in-home or short range communications, mainly basing on the Wi-Fi. The integration of Wimax and Wi-Fi technologies in communication systems requires the framework of intelligent vertical handoff decision algorithms to enable mobile users to seamlessly switch network access and experience uninterrupted service continuity anywhere and anytime by maintaining certain properties, mainly in terms of QoS.
