On the resolution of conflicts for collective pervasive context-aware applications

The main goal of this ongoing dissertation is to define and evaluate an efficient and flexible methodology to detect and solve collective conflicts for pervasive context-aware applications. The solution proposed is flexible enough to be used by applications with different characteristics and also considers the resource constraints, which are typical in pervasive systems. One of the basic motivations to the development of this work is the existence of a great number of collective context-aware applications, specially the ones related to the pervasive computing area. Besides, to the best of the author´s knowledge, until now there is no work in literature that could be applied to many different applications, and that also considers systematically the trade-off between quality of services (QoS) and resource consumption. In this work, QoS means the users´ satisfaction with the application´s tasks. A user is considered satisfied when he/she can perform the tasks he/she has previously demanded.
