An energy‐efficient protocol for multimedia streaming in a mobile environment

Giuseppe Anastasi, Marco Conti, Enrico Gregori, Andrea Passarella, Luciana Pelusi
2005 International Journal of Pervasive Computing and Communications  
Pervasive services and smart environments are becoming more and more popular as an ever-increasing number of people enjoys these services typically by means of portable devices.  ...  We propose a proxybased architecture and an energy-efficient streaming protocol that minimize the energy consumption of the Wi-Fi interface at the mobile device, while guaranteeing the real-time constraints  ...  financial support of the Fondazione Cassa di Risparmio di Pisa in the framework of the SMILE project.  ...

How to Effectively Use Multiple Channels in Wireless Mesh Networks

Pan Li, N. Scalabrino, Yuguang Fang, E. Gregori, I. Chlamtac
2009 IEEE Transactions on Parallel and Distributed Systems  
We find that in spite of interference between both overlapping and nonoverlapping channels, we can still use multiple channels in mesh networks under certain conditions but with care.  ...  Operating on a frequency band occupying several nonoverlapping channels, IEEE 802.11 is now widely used in Wireless Mesh Networks (WMNs).  ...  Project: Wireless multiplatfOrm mimo active access netwoRks for QoS-demanding muLtimedia Delivery (WORLD), under grant number 2007R989S.  ...

Throughput Analysis and Measurements in IEEE 802.11 WLANs with TCP and UDP Traffic Flows

R. Bruno, M. Conti, E. Gregori
2008 IEEE Transactions on Mobile Computing  
Specifically, we develop Markov chain models to compute the distribution of the number of active stations in an 802.11 wireless local area network (WLAN) when long-lived Transmission Control Protocol (  ...  However, very little has been done on investigating the interplay between the collision avoidance mechanisms of the 802.11 MAC protocol and the dynamics of upper layer transport protocols.  ...  He was the general chair of the IFIP-TC6 conferences Networking 2002 and Personal Wireless Communications (PWC) 2003 and the Fourth IEEE Pervasive Computing and Communication (PerCom 2006).  ...

Replicated Web Services: A Comparative Analysis of Client-Based Content Delivery Policies [chapter]

Marco Conti, Enrico Gregori, Willy Lapenna
2002 Lecture Notes in Computer Science  
Replication of Web Services has an important role among techniques that have been developed in order to meet the demand for faster and more efficient access to the Internet.  ...  An analysis of these strategies, and an overall classification, is presented here.  ...  Acknowledgements Work carried out under the financial support of the Italian Ministry for Education and Scientific Research (MIUR) in the framework of the Project "Internet: Efficiency, Integration and  ...
