Mobility management in B3G networks

Abstract

The B3G (Beyond 3G) networking will enable mobile users to roam freely through heterogeneous networks on an all-IP platform. However, mobility handling in such an environment poses new challenges. Traditionally, mobility protocols such as Mobile IP, SIP and SCTP are used to manage mobility in B3G, but they require telecommunication companies to either modify existing network infrastructures or deploy central entities in the network core to handle mobility. This is not feasible in a fully distributed computing environment (e.g., P2P) and mobile ad hoc networks that are part of B3G networking. As an alternative, this paper introduces a middleware component with modularized functionalities to facilitate mobility management in a fully distributed B3G environment. KeywordsB3G, mobility management, middleware, handoffs and service reconfiguration.

User mobility in a Web-based communication system

“…Mobility management enables users to roam freely. It is classified into two groups: telecom-based and service-oriented [4]. Telecom based mobility management can be performed in three layers: application layer (e.g.…”

“…Stream Control Transmission Protocol) and network layer (Mobile IP V4 and V6, eAll-SIP [10]). Consolidating the Telecom-based and service-oriented approaches, [4] presents a middleware-based approach for mobility management. However, our approach is very similar to the application layer approach; it is specific to real-time communication services.…”

“…The communication between two devices is always secured with SSL. Users can define criteria, such as low-cost or high-speed, to influence the decision of choosing a network interface over another or they can explicitly choose a particular interface [15]. It will not always be possible to have all the network interfaces available for communication, in those case user choices will be limited.…”
