Mobility-aware Web services (MWS) should become nowadays an important research area as the number of powerful mobile devices proliferates and their usage for daily business transaction increases. Quality of Web Service (QoWS) assurance for MWS is very crucial for mobile users, however, it is highly affected by the available resources on mobile devices consuming these services and the performance of MWS. In this paper, we propose an architecture for MWS selection based on QoWS and resources requirements. The main purpose of the architecture is to support the client in selecting MWS based on desired QoWS as well as on its device resources availability. This architecture requires a concise description of QoWS and resources requirements. For this purpose, the architecture proposes a verification scheme to verify the conformity of claimed MWS QoWS and required device resources compared to the published one. A set of validation test cases are executed to measure, for each specific MWS operation: the required battery consumption, memory, CPU, and network throughput. The verification is used as input to a three-tier selection process in which selected MWS are those who passed the verification test cases. As proof of concept, a prototype has been implemented to evaluate the verification scheme and show its importance in selecting the best MWS while supporting the QoWS and the required device resource availability.
