: Ambient Intelligence scenarios describe situations in which multitude of devices and agents live together. In this kind ofscenarios is frequent to see the appearance ofconflicts when modifying the state of a device as for example a lamp. Those problems are not as much of sharing of resources as of conflict of orders coming from different agents. This coexistence must deal also with the desire of privacy of the different users over their personal information such as where they are, what their preferences are or to whom this information should be available. When facing incompatibleorders over the state ofa device it turns necessary to make a decision. In this paper we propose a centralised mechanismbased on prioritized FIFO queues to decide the order in which the control of a device is granted.
