QoS measurement issues with DAML-QoS ontology
IEEE International Conference on e-Business Engineering (ICEBE'05), 2005With the industry's efforts in promoting the use of Web services, a huge number of Web services are being developed for the Web. To improve the service provider's competition advantage, it is necessary to support QoS-aware service discovery mechanism as well as the corresponding measurement system.

Predicting unknown QoS value with QoS-Prophet
Proceedings Demo & Poster Track of ACM/IFIP/USENIX International Middleware Conference, 2013We have witnessed the widespread adoption of Collaborative Filtering (CF) in prediction of unknown QoS value. Existing approaches have neglected that CF idea was originated from the processing of subjective data, movies scores for example. However, QoS value is objective, therefore the existing CF-based prediction approaches are not applicable well for

FM-QoS employs a novel communication architecture based on network feedback to provide predictable communication performance (e.g. deterministic latencies and guaranteed bandwidths) for high speed cluster interconnects. Network feedback is combined with self-synchronizing communication schedules to achieve synchrony in the network interfaces (NIs ...

The success of emerging mobile services depends on the serviceability of the underlying wireless networks, expressed in terms of Quality of Service (QoS) provided by a network available to service user at a given geographical location and time. In general, this serviceability is a priori unknown.

In this paper we propose a novel energy-aware QoS model, e-QoS, for application sessions that might across multiple protocol domains. The model provides the QoS guarantee by dynamically selecting and adapting application protocols. To the best of our knowledge, our model is the first attempt to address QoS adaptation at the application session level by

The Quality-of-Service (QoS) in disadvantaged networks is a function of many parameters, including the nature of the physical link over which the disadvantaged network operates. While there exist mechanisms (like specialized versions of TCP) to account for their nature and operate optimally over disadvantaged networks, their operation under adversarial

Proof-of-QoS: QoS based blockchain consensus protocol
Computers & Security, 2019Abstract The consensus protocol is the foundation of all blockchain systems. Existing consensus protocols like Proof-of-Work (PoW) consume a vast amount of energy. However, they are severely limited to transaction throughput. Consensus protocols like Proof-of-Stake (PoS) have been proposed to address this challenge.

AbstractThe authors study a scalable pricing framework for QoS enabled networks that support real-time, adjustable real-time, and non-realtime traffic. The scheme, which belongs to usage-based methods, is independent of the underlying network and the mechanisms for QoS provisioning.

QoS-Aware Hierarchical Mobility Management Using QoS NSLP
2009 5th International Conference on Wireless Communications, Networking and Mobile Computing, 2009It is necessary to provide seamless multimedia services to mobile users. However, due to the effects of host mobility, it is difficult to achieve seamless QoS guarantee. Several solutions have been proposed to couple QoS with mobility management. In this paper, a QoS-aware HMIPv6 solution using QoS NSLP is proposed.

QoS-Based Service Composition under Various QoS Requirements
2013 20th Asia-Pacific Software Engineering Conference (APSEC), 2013There are various approaches for QoS-based web service composition. However, most of them are concerned about the algorithms of service compositions while ignoring the flexibility and expressiveness of users to set QoS constraints. Most of them assume that users could specify accurate QoS constraints easily.
