For avoiding congestion, the amount of injected traffic into the network should be controlled. Differentiated services network can support the quality of service (QoS). For QoS guarantee, Admission control mechanism should be added to the edge routers of the network. The process of deciding to accept or reject a new request is called admission control. In this paper, parameter based admission c...

Distributed multimedia applications require a variety of communication services. These services and different application demands have to be provided and supported within end-systems in an efficient and integrated manner, combining the precise specification of Quality-of-Service (QoS) requirements, application interfaces, multicast support, and security features. The Da CaPo++ system presented ...

QoS (defined as a proper set of quantitative characteristics) analysis is a necessary step for the early verification and validation of an appropriate design, and for taking design decisions about the most rewarding choice, in relation with user requirements. In this paper, we describe an analytical approach for the evaluation of the QoS offered by a family of group communication protocols in a...

Companies nowadays are approaching towards an all IP paradigm by subscribing to different access technology links from several service providers for reliability, redundancy and availability while providing good Quality of Service (QoS). A framework for rule-based converged hybrid network management in multihoming environment is presented. Diversity and dimensionality of the platform’s service, ...

Currently, although prevalent location privacy methods based on k-anonymizing spatial regions (K-ASRs) can achieve privacy protection by sacrificing the quality of service (QoS), users cannot obtain accurate query results. To address this problem, it proposes a new location privacy-preserving k-anonymity method based on the credible chain with two major features. First, the optimal k value for ...

The Dynamic Scalability of resources, a problem in Infrastructure as a Service (IaaS) has been the hotspot for research and industry communities. The heterogeneous and dynamic nature of the Cloud workloads depends on the Quality of Service (QoS) allocation of appropriate workloads to appropriate resources. A workload is an abstraction of work that instance or set of instances that are going to ...

The Cloud Bank model, which is derived from Grid bank [1], is a kind of commerce model of cloud computing that provides pay-as-you-go computing resources. In this model, Cloud Bank is an agent platform of resource transaction. Cloud computing uses the concept of service level agreement (S LA) to control the use and receipt of computing resources from, and by, Cloud Bank. As computing resources ...

Multiple radio access technologies (RATs) are available for the mobile users for the Internet connectivity. Traditional handover algorithms select the RAT based on the signal strength only. But quality of service (QoS) attributes are different for every application like VOIP requires lower network delay while video streaming application requires higher data rate. Therefore, these QoS parameters...

Designing of the composite services with desired quality is an interesting challenge in web service environments. In a QoS-aware web service composition, appropriate services with acceptable quality are selected among several functionequivalent candidate services. The selection is performed in such a way that creates a composition with optimal quality which can satisfy user’s constraints. In th...
