We present SoRTSim, a high-level simulator designed to evaluate tools built over the middleware to support additional services besides the stan- dard ones, particularly to allow the execution on Grid platforms of appli- cations with strict QoS requirements, up to Soft Real-Time. SoRTSim has been designed to be quite general and to be easily...

fined by the administrators of the physical organizations and of the Grid middleware. This approach does not require support for access control in the middleware, but since changes in the access control policy of the Virtual Organization imply the involvement of one or more administrators, it lacks the flexibility needed in several application...

The access to Grid resources depends on rules defined by the administrators of the physical organizations and of the Grid middleware. This approach does not require support for access control in the middleware, but since changes in the access control policy of the Virtual Organization imply the involvement of one or more administrators, it...

ABSTRACT – Due to the proliferation of wideband and Internet technologies in the last decade, the risk of security threats hidden in single packets arose. This had taken ISP networks to the adoption of Intrusion Detection Systems, enhancing the basic routing with packets inspection, in order to provide a secure connection service. Currently,...

Vehicular Ad hoc Network (VANET) is a wireless network formed on the fly among vehicles connected by wireless links. A VANET application can learn about the context by acquiring and parsing beacons periodically broadcasted by other vehicles. In this paper we investigate the requirements of the applications that use vehicle beaconing to increase...

The 4W project system allows providing users with location and time contextualized cues that are generated automatically starting from user expressed needs. The system comprises a server side engine capable of reasoning to find out which location categories have to be searched for and a mobile device to track user location and provide...
