چکیده

Emerging mobile applications rely their delivery on the serviceability of the underlying wireless networks. However, this serviceability, expressed in terms of quality of service (QoS) provided by a network available to a service user at a given geographical location and time, is a priori unknown. In turn, it influences the application-level QoS provided to a mobile service user. As a solution we research the QoS-predictions service, providing predictions for QoS of networks available at a given user’s geographical location and time. In a case study we prove the feasibility of deriving predictions from historical data collected by a mobile service user. This mobile user is a patient, using his health telemonitoring service in his daily environments for a period of one month. We consider the QoS-predictions service as a novel support for mobile services operational in 4G heterogeneous network environments..

QoS-Predictions Service: Infrastructural Support for Proactive QoS- and Context-Aware Mobile Services (Position Paper)

Today’s mobile data applications aspire to deliver services to a user anywhere anytime while fulfilling his Quality of Service (QoS) requirements. However, the success of the service delivery heavily relies on the QoS offered by the underlying networks. As the services operate in a heterogeneous networking environment, we argue that the generic information about the networks’ offered-QoS may en...

Improving Success Ratio in Multi-Constraint Quality of Service Routing

Multi-constraint quality-of-service routing will become increasingly important as the Internet evolves to support real-time services. It is well known however, that optimum multi-constraint QoS routing is computationally complex, and for this reason various heuristics have been proposed for routing in practical situations. Among these methods, those that use a single mixed metric are the mo...

QoS-Based web service composition based on genetic algorithm

Quality of service (QoS) is an important issue in the design and management of web service composition. QoS in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. In recent years, the number of available web services has proliferated, and then offered the same services increasingly. The same web ...

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR

Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

A Novel Fuzzy Logic Base Scheduling Mechanism for Service Differentiation in IP Networks

Quality of Service (QoS) refers to a set of rules or techniques that help the network administrators use the available network resources optimally to manage the effects of congestion and to treat the applications according to their needs. The differentiated services architecture (DiffServ) allows providing quality of service to users. The major DiffServ premise is that individual flows with sim...
