This paper outlines an architecture that intends to ensure Quality of Service (QoS) to applications using the publisher-subscriber paradigm. The key idea is to subscribe information not only by subject and content but also according to QoS parameters. This must be done with cooperation of all intervenients: publishers, which should tag information they are producing with application-level QoS p...

MANET is a self organized and self configurable network where the mobile nodes move arbitrarily. The mobile nodes can receive and forward packets as a router. Routing is a critical issue in MANET and hence the focus of this paper along with the performance analysis of routing protocols. We compared three types of routing protocols i.e. proactive, reactive and hybrid. All the MANETs routing prot...

In this paper, the authors develop a comprehensive framework for QoS management based on soft probabilistic contracts. The authors approach also encompasses general QoS parameters, with “response time” as a particular case. In addition, the authors support composite QoS parameters, for example, combining timing aspects with “quality of data” or security level. They also study contract compositi...

This specification defines a new mobility option, the Quality-ofService (QoS) option, for Proxy Mobile IPv6. This option can be used by the local mobility anchor and the mobile access gateway for negotiating Quality-of-Service parameters for a mobile node’s IP flows. The negotiated QoS parameters can be used for QoS policing and marking of packets to enforce QoS differentiation on the path betw...

This position 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 specific...

Sensor networks consist of small, lowpower, low-energy (stationary) nodes used for monitoring parameters such as temperature, humidity, and motion. Routing is a critical issue in WSN and hence the focus of this paper along with the performance analysis of routing protocols. The growing interest in WSN technique has resulted in many routing protocol proposal. The objective of this paper is to cr...

In this paper we will design architecture for cloud computing services with QoS by supported scheduling algorithm for resource allocation. Cloud generally uses virtualization technology which is specially designed for maximum resource utilization. The QoS of cloud environment for any kind of resource utilization is achieved feasibly by using QoS-aware Cache Replacement algorithm. This algorithm...

A contribution for the definition of a distributed transport architecture in a global Quality of Service (QoS) framework within TCP/IP stack is presented in this paper. A new distributed transport strategy is suggested, making use of dynamic transport agents located strategically along the end-to-end path. Dynamic QoS management, focused on transport layer based QoS adaptation for tolerant mult...

This paper presents a CORBA-based Quality-of-Service (QoS) management framework for distributed multimedia services and applications. The QoS MIB has been defined for the QoS management of various multimedia services, and consists of information objects that represent a set of layered QoS parameters. These managed objects are organized into four logical groups: service, application, system, and...
