Mobility Management in Wireless Systems

Mobility Management in an IP-based Wireless ATM Network

Traditionally, mobility support in IP was not designed for wireless systems but rather for relocation of wired terminals in a new sub-network. With new wireless technology, the question arises how mobility for such systems can be supported on the Internet. The extension of a wireless ATM access network to support native IP access with IP-based mobility management is described. Using standard pr...

Wireless Information Systems

Wireless computing is a promising new paradigm for building information systems that allows greater flexibility concerning distribution, costs, mobility and introduction of data services. On the other hand cordless computing brings up many challenging data management and database problems due to technical restrictions like limited bandwidth and unreliability of wireless communication. In this p...

Quality-Oriented Mobility Management for Multimedia Content Delivery to Mobile Users

The latest advances in wireless data access technologies and increased popularity of mobile computing have enabled the development of the future mobile Internet. The various wireless technologies and standards already developed or under development support the existence of a highly heterogeneous wireless communication environment in which mobile users access the network from diverse devices and...

Toward an energy efficient PKC-based key management system for wireless sensor networks

Due to wireless nature and hostile environment, providing of security is a critical and vital task in wireless sensor networks (WSNs). It is known that key management is an integral part of a secure network. Unfortunately, in most of the previous methods, security is compromised in favor of reducing energy consumption. Consequently, they lack perfect resilience and are not fit for applications ...

Mobility Management in Next Generation All-IP Based Wireless Systems

Appeared as Part of "mobility Management in next Generation Wireless Systems," Mobility Management Protocols for Wireless Atm Networks

This paper presents a survey of mobility management protocols for Wireless Asynchronous Transfer Mode (WATM) networks. Basic architectural assumptions for WATM networks are presented, followed by an overview of location registration, call delivery, and terminal paging techniques. Next, a collection of protocols for handoo connection rerouting is examined. The paper concludes with a discussion o...
