Abstract. The proliferation of group-centric computing and communication motivates the need for mechanisms to provide group access control. Group access control includes mechanisms...
In mobile ad hoc networks, synchronous communication mechanisms appear to be not suitable, since these assume that the involved entities are present at the same time during the in...
There exist distributed scenarios in which the need for dynamism, mobility, and adaptivity, has to be addressed with highly dynamical approaches. These scenarios present different ...
Massively deploying RFID systems while preserving people's privacy and data integrity is a major security challenge of the coming years. Up to now, it was commonly believed th...
In this paper, we consider semantic service discovery in a global computing environment. We propose creating a dynamic overlay network by grouping together semantically related ser...
