A model of quality-in-use for service-based mobile ecosystem

Abstract

Mobile devices have a drawback of limited computing power and resources. As an effective way to remedy the limitation, service-based mobile computing is emerged. However, there exists a challenge in managing quality of mobile applications at runtime, i.e. quality-in-use quality, due to the dynamic natures of services and limited controllability of services by consumer applications. An autonomous service management, such as service-based mobile ecosystem (SME) introduced in our previous work, is one of the promising solutions to tackle this challenge, which inevitably requires continuously monitoring quality-in-use of services at runtime. Hence, it is required to define quality-in-use qualities which play a role of figuring out problematic situations. Hence, this paper presents a quality model for measuring the quality-in-use of services in SME. The quality model is used as the basis for diagnosing various elements and further performing selfstabilizing activities in SME. © 2013 IEEE.
