The work presented here was carried out within the FABRIC project1, which aimed at the integration of middleware standards used in home networks to provide high quality streaming over heterogeneous network s. In this paper we propose an adaptive QoS framework for efficient resource management, called the Matrix approach. The Matrix is a concept to abstract from having detailed technical data at...

From the perspective of selecting service by QoS attributes, a computation method of QoS expectation value, which is based on Algorithm Prim, was presented to provide support for selection of service. On the basis of the ability of service providers, by Algorithm Prim, this method succeeded in calculating a set of balanced expectation values of QoS. Selection of service based on these QoS value...

The Internet has evolved into a shared, integrated platform of a broad range of applications with different Quality-of-Service (QoS) requirements. Routers are an important part of the Internet and play a critical role in assuring QoS. A router is usually placed between two networks to receive data packets from one network and then transmit those data packets to another network if necessary. Dat...

This Recommendation specifies performance requirements and objective measuring methods of quality of service (QoS) for the delivery of digital video broadcasting services over broadband Internet protocol (IP) networks. The specified performance requirements are based on an IP QoS ranking at various levels, from “excellent” to “out-of-service”. They rely on the objective end-to-end measurement o...

Mobile applications and mobile application environment of next generation networks require enhanced quality of service (QoS) to support user’s service level agreement (SLA). This paper presents an adaptation technique at transport layer to minimize the impact of varying and adverse network condition along with security and priority to satisfy the SLA. The paper extends the transport layer funct...

We describe a framework for providing quality-of-service guarantees within the endsystem for networked multimedia applications. Our framework integrates four components namely, QoS speciication, QoS mapping, QoS enforcement, and a protocol implementation model. The framework allows QoS speciications to be at a high level so that an application can easily specify its requirements using a small n...

The performance of network and communication software is a major concern for making the electronic commerce applications in a distributed environment a success. The quality of service in electronic commerce can generically be measured by convenience, privacy/security, response time, throughput, reliability, timeliness, accuracy, and precision. We present the quality of service parameters, softw...

Wireless Sensor Networks consist of small, low-power, low-energy nodes used for monitoring environmental parameters such as temperature, humidity and motion. Routing is a critical issue in WSN and hence the WSNs are required to provide different levels of Quality of Services (QoS) based on the type of applications. Due to resource constraints like processing power, memory, bandwidth and power s...

Monitoring the change of network performance parameters is a key to realize the QoS management in ATM networks. The OAM performance management function defined by ITU-T, however, simply monitors network performance and reports sratus information. It can not give QoS management an enough support. In terms of the relationship between QoS and network performance parameter, an ATM layered QoS manag...

Group communication in wireless multimedia networks must consider the Quality of Service (QoS) parameters for efficient and quality aware multicast route computation. QoS parameters such as bandwidth, channel reliability, buffers, delays, jitters, etc. play a vital role in wireless multimedia networks. Multicast tree development for group communication must press for more than one or two QoS pa...
