Recently, there have been many efforts to develop Wireless Sensor Networks (WSN), but no one can deny the fact that QoS support is still one of the least explored areas in this domain. In this paper, we present QoS support in WSN while highlighting the QoS mapping issue, a complex process in which QoS parameters are translated from level to level and we present a case study of a TDMA tree-based...

* It is becoming increasingly commonplace for multiple applications with different quality of service (QoS) requirements to share the resources of a distributed system. Within this environment, the resource management algorithms must take into account the QoS desired by applications and the ability of the system resources to provide it. In this paper we present a taxonomy for specifying QoS for...

With the extensive growth of the Internet, wireless technology, and multimedia applications, Quality of Service (QoS) monitoring and measurement of the networks have become important. Network measurements are carried out to obtain information about important QoS parameters such as delay, loss and jitter. Each type of multimedia applications has its own requirements and limits on these parameter...

This paper deals with the Quality of Service (QoS) negotiation for multicast connections. First, we show that in the multicast case, the QoS parameters may be separated into two classes, namely the parameters whose scope is the whole multicast connection and those whose scope is limited to each receiver separately. Then, after a brief presentation of the enhanced QoS defined in the OSI95 transp...

In today’s IT environments customers often have to rely on best-effort services such as IP and e-mail. In order to have a competitive advantage, service providers offer different kinds of guarantees for their services which are often called Quality of Service (QoS) parameters. Parameters in this sense are service-specific, and are not limited to classical network QoS parameters (e.g. delay, jit...

A recent major development in computer technology is the advent of wearable computer systems. Wearable computer systems employ a wireless universal serial bus (WUSB), which refers to a combination of USB with the WiMedia wireless technical specifications. In this study, we focus on an integrated system of WUSB over wireless body area networks (WBANs) for wireless wearable computer systems. Howe...

This memo defines a set of general control and characterization parameters for network elements supporting the IETF integrated services QoS control framework. General parameters are those with common, shared definitions across all QoS control services.

This paper addresses the issue of supporting quality-of-service (QoS) parameters in distributed publish-subscribe systems. It advocates that QoS parameters should be handled using the same constructs as other information regarding events, such as their type or content. At the same time, we claim that the use of a consistent set of mechanisms should not preclude to decouple the specification of ...

The break of the 2 and the 3 century is in telecommunications characterised by an integration of various services that are provided by different networks into a single network. This trend is called service integration or network integration. Currently, this integration is not only focused on research work, but the solutions come to be implemented in practice as well. Service integration results...

This paper considers the problem of application-level QoS control in group collaboration systems. The QoS parameters considered, latency, jitter, packet-loss, and asynchrony, are controlled by the receiver. The QoS control is based on a novel protocol composition-based approach, wherein the protocol is modularized such that each module controls a single QoS parameter. Each module is then assign...
