Quality of Service Predictions Service: QoS Support for Proactive Mobile Applications and Services

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..
