Abstract-- The safety control problem for hybrid automata with imperfect mode information and continuous control is addressed. When the controller does not have access to the mode ...
We consider opportunistic spectrum access for secondary users over multiple channels whose occupancy by primary users is modeled as discrete-time Markov processes. Due to hardware...
Abstract—This paper considers an uplink time division multiple access (TDMA) cognitive radio network where multiple cognitive radios (secondary users) attempt to access a spect...
Abstract. We consider the problem of developing an abstract metamodel of access control in terms of which policies for protecting a principal's private information may be spec...
In a reputation-based trust-management system, agents maintain information about the past behaviour of other agents. This information is used to guide future trust-based decisions...
