Quality of service in MAQAME Architecture

Due to the advance in Wireless technology, ubiquitous Internet access, and improvements to mobile device technology, mobile services flourishe considerably and will continue to do so as the number of mobile users begins to multiply. However, this range of published mobile services introduces a new challenging problem, in addition to the diversity of discovery protocols and the heterogeneity of interaction protocols. This challenge concerns the ability to find at runtime relevant mobile services in term of QoS for users among those implementing similar functionalities according to their device constraints and their preferences. To this end and taking into account the diversity of QoS specification languages, we present in this paper an approach to determine at runtime the appropriate needed mobile service related to device capabilities, client preferences, execution context and mobile service features. This approach is currently under implementation on MAQAME Architecture suggested in a previous work.
