Emilio Leonardi

leonardi [at] polito [dot] it

I am a professor  in the  Dipartimento di Elettronica e Telecomunicazioni at  Politecnico di Torino.

I got a Dr.Ing degree in Electronics Engineering in 1991 (summa cum laude) and a Ph.D. in Telecommunications Engineering in 1995 both from Politecnico di Torino.

In 1995, I spent one year at the Computer Science Department of the University  of California, Los Angeles (UCLA), with Prof. M. Gerla, where I  was involved in the Supercomputer-SuperNet (SSN) project, aimed at the design  of a hierarchical network composed of  an  optical backbone that interconnects several high speed wormhole routed  networks.

In the Summer 1999 I visited the ``High-Speed Networks Research Group'',  at Bell Labs - Lucent, where I participated in the design of efficient scheduling  policies for high  capacity input-queued switches. 

During the Summer 2001 I  visited Prof. Balaji Prabakhar,  at  Stanford University,  EE Dept., where I investigated  the performance of scheduling policies for input-queued switches.

In  summer 2003 I  visited the IP group at SprintLabs-Burlingame CA, where I worked on  the definition of efficient and accurate  algorithms for the estimation of traffic matrices in IP backbone networks starting from  link load measurements.

At last, in summer 2012 I visited the network division at NEC laboratories, Heidelberg, Germany where I  participated in the definition of smart policies for  prefetching/caching video contents in next generation mobile networks and to the definition of smart policies  for  content advertisement.

I  have participated in several National and European   projects such as  IST-SONATA, IST DAVID, NoE ePhoton-1 and  NoE Euro-FGI, FET STAMINA.  I have  is also being involved in several consulting and research projects with private industries, including Lucent  Technologies, British Telecom, Alcatel, IBM  and TILAB, Microsoft Research.

I was the  scientific coordinator of the three yeras long  European 7-th FP  STREP project  NAPA-WINE on P2P streaming applications, involving 11 European research institutions, operators and manufacturers.
I have co-authored over 200 papers published in leading international journals and presented in international conferences, most of them in the area of telecommunication networks. I have also coathored four patents.

I participated in the organizing and  technical  committees of several  conferences including IEEE Infocom and  ACM MobiHoc.   I am serving in the editorial board of IEEE Transactions on Parallel and Distributed Systems.  I was  co-guest editor of the special issue on  ``High-Performance Optical/Electronic Switches/Routers for High Speed Internet'' for  the ``IEEE Journal on Selected Areas of Communications''.

 I received  the best paper award at the following conferences: 

  • IEEE Globecom - High Speed Networks Symposium, 2002.
  • IEEE High Performance Switching a Routing Symposium (HPSR), 2006.
  • 14-th IEEE/ACM   International Symposium on Modeling, Analysis, and Simulation of Computer and Telecommunication Systems (MASCOTS'06), 2006.
  • 12-th IEEE International conference  on Peer to Peer Computer, (P2P'12), 2012







Current areas of interest: 
  • Social networks/graphs
  • Network Science - complex networks
  • Crowdsoucing
  • Networks of  Caches/ CDN
Former areas of interest: 
  • Stochastic geometry and wireless networks
  • Scaling laws of wireless networks
  • P2P streaming
  • Peer assisted VoD
  • Fluid models of TCP/IP networks
  • Scheduling algorithms for IQ switches
  • Stochastic Lyapunov function and queues stability
  • Wormhole networks  (very  old topic)
  • Optical networks  (very very old topic)

In conclusion, I can say that  my research (especially in the last years)  has been maily oriented to  the understanding of fundamental dynamics in compuer networks and large scale distributed systems.  In general, I like to tackle  networking problems that are mathematically challenging for an engineer, like me.
