-Next Generation Wireless system (NGWS) consists of heterogeneous wireless networks. The heterogeneous wireless network should be always best connected in order to satisfy the seamless characteristics in mobile communication. NGWS call for the integration and interoperation of mobility management techniques in heterogeneous networks. One of the research challenges for NGWS is the design of inte...

This paper considers three applicationsVoIP, mobile Web access and mobile server-based data transfersand evaluates the applicability of various IP-based mobility management mechanisms. We first survey the features and characteristics of various IP mobility protocols, such as MIPv4, MIPv6, MIP-RO, SIP, CIP, HAWAII, MIP-RR and IDMP, and then evaluate their utility on an application-specific basis...

Abstract: Increasing demand for mobility in wireless data networks has given rise to various mobility management protocols. The protocols use signalling messages to maintain reachability of mobile nodes. Increase in the number of mobile nodes gives rise to the scalability issues that need to be dealt with to avoid performance degradation of the network. In this paper, we have developed analytic...

Software mobile agents provide an efficient method for reducing data traffic and latency in mobile software applications. In this paper, we identify that current systems use two basic methods for facilitating a request for mobility. We define Mobility Patterns, and we argue that there are another 6 mobility patterns that can improve data traffic or latency if applied in specific cases. We also ...

Future wireless networks have two widely accepted characteristics. Firstly, they will be based on all-IP based network architecture and secondly they will integrate heterogeneous wireless access technologies. As a result, there exist today a multitude of solutions aimed at managing these imminent challenges. These solutions are at varying stages of deployment, from purely analytical research, t...

Over the past few years, modern mobile subscriber devices such as Smartphones, tablets and PDAs have become more and more popular which use network resources in a more aggressive way and last for longer durations involving dramatically increasing traffic volumes. But traditional mobility management schemes have hardly taken this issue into account. Distributed mobility management is considered ...

Ever increasing user demands and development of modern communication technologies have led to the evolution of communication networks from 1 Generation (1G) network to 4G heterogeneous networks. Further, 4G with heterogeneous network environment will provide features such as, “Always Best Connected”, “Anytime Anywhere” and seamless communication. Due to diverse characteristics of heterogeneous ...

For IP-based mobile networks, efficient mobility management is vital to provision seamless online service. IP address starvation and scalability issue constrain the wide deployment of existing mobility schemes, such as Mobile IP, Proxy Mobile IP, and their derivations. Most of the studies focus on the scenario of mobility among public networks. However, most of current networks, such as home ne...

Mobility management, which includes location management and handoff management, is essential in cellular wireless networks to provide service to mobile users. Location management enables call delivery to mobile users, while handoff management maintains the connectivity of ongoing calls while users move between cells. In next generation networks, mobile users will avail themselves with terminals...

To support IP-mobility of networks in motion, IETF proposed Network Mobility (NEMO) protocol that uses various signaling messages to ensure connectivity of the mobile nodes with the Internet and to maintain security of ongoing sessions by protecting the binding updates. As the next-generation wireless / mobile network is supposed to be a unified network based on all-IP technology, compounded by...
