ABSTRACT
In cellular networks, QoS degradation or forced termination may occur when there are insufficient resources to accommodate handoff requests. One solution is to predict the trajectory of mobile terminals so as to perform resource reservations in advance. With the vision that future mobile devices are likely to be equipped with reasonably accurate positioning capability, we investigate how this new feature may be used for mobility predictions. We propose a mobility prediction technique that incorporat ....etc

QoS in Cellular Networks Based on MPT
In recent years, there has been a rapid increase in wireless network deployment and mobile device market penetration. With vigorous research that promises higher data rates, future wireless networks will likely become an integral part of the global communication infrastructure. Ultimately, wireless users will demand the same reliable service as today's wire-line telecommunications and data networks. However, there are some unique problems in cellular networks th ....etc

Today's Internet provides a best effort service. It processes traffic as quickly as possible, but there is no guarantee at all about timeliness or actual delivery: it just tries its best. However, the Internet is rapidly growing into a commercial infrastructure, and economies are getting more and more dependent on a high service level with regard to the Internet. Massive (research) efforts are put into transforming the Internet from a best effort service into a network service users can really rely upon.Commercial demands gave rise to the idea ....etc

ABSTRACT

An increasing demand for Quality of Service on the Internet has led to various developments in that area. Differentiated Services is a technique to provide such Quality of Service in an efficient and scalable way.

Management of computer networks involves both monitoring of running services as well as the configuration of those services. On the Internet, the SNMP protocol is used to retrieve and set variables in a MIB. In order to facilitate the management of routers equipped with Differentiated Services, the IE ....etc

The user of any system has moral right to get services of expected quality level. To fulfill the requirement of Quality of Services (QoS), mobile system and service provider reserve resources. But this unavoidable reservation results into an inefficient design which requires more power. Therefore, the system must adapt itself with respect to changes in user requirement of QoS. Thus we require a system-on-chip (SoC) architecture which facilitates runtime reconfiguration. Field Programmable Gate Arrays is one that supports aforementioned technolo ....etc

Switch Architecture Guaranteeing QoS Provision and HOL Blocking Elimination

Abstract

QoS support and congestion management techniques become essential to achieve good network performance in current high-speed interconnection networks.
The most effective techniques traditionally considered for both issues, however, require too many resources for being implemented.
In this paper we propose new cost-effective switch architecture able to face the challenges of congestion management and, at the same time, to provide QoS.
The efficiency of o ....etc

Abstract
The present network-layer multicast routing protocols build multicast trees based only on hop count and policy. If a tree cannot meet application require- ments, the receivers have no alternative. A general and modular architecture that integrates alternate path routing with the network multicast services is proposed. This enables individual multicast receivers to reroute a multicast tree according to their needs, subject to policy restrictions. Many Internet multicast applications such as teleconferencing and remote diagnosis have Q ....etc
