With the growing number of mobile nodes and projections that this number will far exceed that of stationary nodes, mobility management becomes an important aspect of the next generation networks. Mobile operators are therefore looking to deploy a functional and optimized protocol that allows management of mobility while offering additional functionalities, such as simultaneous multi-access and ...

While the 3G wireless system is still under deployment world-wide, pilot research has been targeted to the next generation (NG), whose full scope is not yet well defined. One feature of NG should be its heterogeneous communication environment, where different generation cellular systems coexist and various wireless access networks and corresponding services are used. Advanced mobility managemen...

The advances in hardware and wireless technologies have made mobile communication devices affordable by a vast user community. With the advent of rich multimedia and social networking content, an influx of myriads of applications, and Internet supported services, there is an increasing user demand for the Internet connectivity anywhere and anytime. Mobility management is thus a crucial requirem...

As the future generation networks are envisioned to be heterogeneous in nature, seamless mobility in such networks is an important issue. While IETF work groups have standardized various mobility management protocols, such as Mobile IPv6 (MIPv6), Fast Handovers for Mobile IPv6 (Predictive FMIPv6, and Reactive FMIPv6), Hierarchical Mobile IPv6 (HMIPv6), Proxy Mobile IPv6 (PMIPv6) and Fast Handov...

The upcoming generation of the wireless network may integrate the several numbers of existing wireless networks within such interesting efforts and concept for the mobility management. There are already several techniques are being used for the improvement of mobility management such as handover technique with vertical and horizontal part. The existing technique are providing designing based in...

In recent years several wireless communication standards have been developed and more are expected, each with different scope in terms of spatial coverage, radio access capabilities, and mobility support. Heterogeneous networks combine multiple of these radio interfaces both in network infrastructure and in user equipment which requires a new multi-radio framework, enabling mobility and handove...

This paper addresses the issue of mobility and QoS management principles as well as the mobility and QoS management integration in the sense of build a QoS-aware architecture for mobile Internet. After covering the mobility and QoS management principles and integration, this paper also proposes a new QoS-aware architecture for mobile Internet. This new architecture takes into account the specif...

Mobile IPv6 (MIPv6) is a work in progress IETF standard for enabling mobility in IPv6 networks and is expected to have wide deployment. We investigate an integrated mobility and service management scheme based on MIPv6 with the goal to minimize the overall network signaling cost in MIPv6 systems for serving mobility and service management related operations. Our design extends IETF work-in-prog...

IP flow mobility enables selected traffic to offload among various access networks. However, until now, only flow mobility schemes in the centralized architecture were considered. In this paper, we propose a flow mobility-enabled scheme based on the distributed mobility management networks to address the scalability issue and single point failure problems which the centralized approaches suffer...
