PERFORMANCE EVALUATION OF THE MOBILITY MANAGEMENT TOWARDS 4G WIRELESS NETWORKS

Abstract

ABSTRACT The next generation of 4G wireless communication networks is supposed as a communication of different wireless access technologies (vertical communication) permitting the user with the best anywhere, anytime connection and developing the system resource utilization. So mobility management is crucial to ubiquitous computing and requires network management operations to avoid service degradation through this networks heterogeneity. Both location management and handoff management constitute mobility management. Handoff management is one of the mobility management components; it maintains mobile network's connections active while roaming or switching into a new area. The location management is a tracking process for the active mobile during his roaming without a call. In this work the performance of mobility management is evaluated during handoff and location management processes
