Analysis of Mobility Protocols for Multimedia

This chapter provides comprehensive analysis of several generations of mobility protocols (e.g., 1G, 2G, 3G, and 4G) in order to extrapolate the common abstract functions during a mobility event. It describes how discovery, configuration, authentication, security association, and media routing functions associated with a mobile's handoff are performed for each of the cellular and IP-based mobility protocols and then maps the respective network parameters for these mobility protocols to each of the common mobility functions. A comparative analysis and extrapolation of the abstract primitives can help to design an optimized mobility system with a given resource constraints and build the optimization mechanisms for each these mobility functions.
