INTEGRATION OF FOURTH GENERATION WITH HETEROGENEOUS NETWORKS

Abstract

ABSTRACT

The rapidly growing demand for “anywhere, anytime” high-speed access to IP-based services is becoming one of the major challenges for mobile networks. As the demand for mobility increases, mobile terminals need to move freely across heterogeneous networks, posing the c5hallenge of network integration into an All-IP access platform.

The objective of this research is to discuss the possible integration techniques to integrate wireless heterogeneous networks and also to clarify the reasons of selecting Mobile IP as a preferable integration solution. Moreover, the research illustrates the strengths points of MIPv6 over MIPv4 and proposes three integration techniques namely Lazy Cell Switching, Eager Cell Switching and Parametric Cell Switching. The handover performance was simulated using a MATLAB tool and results were studied and evaluated based on three metrics which are: 1- Handoff latency (network outage time), 2- Number of performed handoffs and 3- User value which offers the most optimal network.
