Flexible and Modular Support for Multicast Rate Adaptation in WLANs
2013
The flexibility and virtualization capabilities provided by wireless cards have received significant attention as a means to reduce development costs. In this paper we present a modular architecture that exploits the features provided by emerging PHY and MAC implementations to rapidly develop new rate adaptation algorithms for multicast trans- mission in wireless LANs. We validate our solution by developing three rate adapta- tion algorithms that use an innovative sensing mechanism to evaluate the frame recep- tion correlation of the members of the multicast group. The experimental results obtained on a real-life testbed show that our solutions permit to increase the performance of multicas…
Comunicare per valorizzare: un progetto per il sito Archeologico di Eraclea Minoa
2019
Innovativi processi e linguaggi multimediali stanno trasformando i tradizionali sistemi di valorizzazione dei beni culturali. La pervasiva diffusione delle tecnologie digitali e virtuali ha infatti permesso l’elaborazione di strumenti e metodi particolarmente efficaci per la comunicazione e valorizzazione anche degli aspetti immateriali di oggetti e siti caratterizzati dal loro valore storico e dai significati culturali che trasmettono. In particolare la complessità e ricchezza d’implicazioni culturali proprie dei siti archeologici, richiedono oggi efficaci elementi di informazione e comunicazione per attivare coinvolgimento e piena consapevolezza nei visitatori, anche se in presenza di poc…
Estimating Applicability of New Mobile Content Formats to Organizational Use
2003
Innovations on information and communication technology reshape organizational communication. Our ability to estimate applicability of new technologies and content formats to organizational use has been limited to generic quantitative methods at the level of technologies and industries and elaborate qualitative methods targeting specific phenomena at the organizational level. In this paper we estimate quantitatively the applicability of MMS, SMS, XHTML, and XML to organizational use based on an analysis of all communication of an organization unit. We enumerate over 700 communication genres using a genre-based information systems planning method, categorise them with taxonomy of communicati…
Wireless ATM : handover issues
1998
Basic aspects of cellular systems and the ATM transmission technology are introduced. Wireless ATM is presented as a combination of radio ATM and mobile ATM. Radio ATM is a wireless extension of an ATM connection while mobile ATM contains the necessary extensions to ATM to support mobility. Because the current ATM technology does not support mobility, handover becomes one of the most important research issues for wireless ATM. Wireless ATM handover requirements are thus analysed. A handover solution relying on two inter-related handover protocols is presented and evaluated. Future research is needed to compare this solution with options presented by earlier research and possibly combine the…
