Abstract

Problem statement: Next-generation mobile networks are evolving towards network architectures relying entirely on IP. Approach: These networks had to be scalable in order to support future IP traffic, namely new multimedia services and real time applications, while providing an effective mobility management mechanism to cope with increasingly mobile users. In addition to global connectivity, next-generation mobile networks will have to offer quality of service guarantees such as assured bandwidth, low rate of packet loss, low delay and jitter. Results: In this study, we proposed an MPLS-based architecture for mobility management and end-to-end quality of service support in fourth-generation all-IP mobile networks (MAFI). Conclusion/Recommendations: Our scheme aimed to reduce handoff latency by implementing the fast handover technique and to increase the robustness and flexibility of the mobile system. The results obtained confirm the efficiency of MAFI when compared to FHMIPv6 and others schemes well-known in the literature.

Summary

Introduction

At a time when the industry is upgrading its second generation networks to 3G technology, the research community is looking into fourth generation networks and its challenges. Each generation of networks brings in a wealth of solutions, technologies and a number of new problems and research challenges. Third Generation (3G) mobile systems were designed to support high speed multimedia traffics including data and voice, while fourth Generation (4G) networks will bring wireless systems to the All-IP Net-era. All-IP networks apply the IP technology end-to-end, from the mobile user to the gateway that connects it to the Internet. A close look at fourth-generation networks shows that they will provide fully converged services, will offer mobile access in a ubiquitous fashion, will support diverse and heterogeneous user devices, will be autonomous and will depend heavily on software[9]
