Mobile IPv6 is designed to maintain its connectivity while moving from one network to another. It is adopted in 3G CDMA networks as a way to maintain connectivity when the mobile node (MN) moves between access routers. However, this handover procedure requires not only movement detection by the MN, but also the acquisition of a new Care-of Address and Mobile IPv6 registration with the new care-...

In this paper, a novel architecture for interworking of the Wireless Local Area Network (WLAN) and the Third Generation (3G) mobile cellular network is presented. This architecture is a hybrid model with additional controls compared with the existing architectures and the use of IP Multimedia Subsystem (IMS), as an arbitrator for coupling and real-time session management. Furthermore, a new net...

This document discusses the issues associated with mobility management for dual stack mobile nodes. Currently, two mobility management protocols are defined for IPv4 and IPv6. Deploying both in a dual stack mobile node introduces a number of problems. Deployment and operational issues motivate the use of a single mobility management protocol. This document discusses such motivations. The docume...

In the fast handover, when a mobile node moves to...

One of the prominent reason for ineffective communication in call center telephone conversations is primarily due to the manner in which the voice agents speak and not necessarily due to what they speak. Speaking rate, a non-linguistic aspect of speech, is a critical factor affecting intelligibility and comprehension of speech in general and specifically in call center telephone conversations. ...

104 ABSTRACT Mobile IP is the underlying technology for support of various mobile data and wireless networking applications. Mobile devices have IP addresses. With the advent of packet based mobile data applications and the increase of wireless computing, there is a corresponding need for the ability for seamless communication between the mobile node device and the packet data network (PDN) suc...

In this paper we present a scheme that enables a mobile user to perform a ”QoS-conditionalized” handoff when moving to an overlapping area in Mobile IPv6. The idea is to use a QoS hop-by-hop option piggybacked in the binding messages for QoS signaling and conditionalize a handoff upon the availability of sufficient resources along the new transmission path. Our scheme builds upon the hierarchic...

Distributed architecture offers many advantages compared to centralized architecture in terms of providing multimedia services. However, as a trade-off, distributed architecture requires that peers contribute a portion of their bandwidth and computational capacity to maintain the mutual overlay interconnection. This requirement develops into a serious problem for mobile users and wireless infra...

This paper investigates the interworking between wireless ad hoc networks and the Internet. In other words, we consider access to the Internet via a multihop wireless network. The heterogenous communication is established with the help of specific access routers, which serve as gateways between the two kinds of networks. We describe the network scenario and its basic protocol architecture. The ...
