Coded Caching: Past, Present, Future

IEEE ITW 2020, Riva del Garda, Italy
Plenary Lecture


Coded caching has emerged as a powerful and elegant idea for content distribution over communication networks. Since the initial work of Maddah-Ali and Niesen, a vast set of theoretical results have been developed in the network coding and information theory community. These results range from solving more and more complicated theoretical "puzzles" (i.e., highly involved, but somehow practically irrelevant problems) to addressing more concrete problems of practical relevance for applications. Yet, questions still remain about whether such schemes will ever be used in the real world on a vast scale. This talk provides an account of some recent exciting results including the real-world implementation of coded caching on actual wireless networks, addressing some of the residual skepticism about the feasibility and actual gains achievable by these schemes.

Giuseppe Caire (S '92 -- M '94 -- SM '03 -- F '05) was born in Torino, Italy, in 1965. He received the B.Sc. in Electrical Engineering from Politecnico di Torino (Italy), in 1990,  the M.Sc. in Electrical Engineering from Princeton University in 1992  and the Ph.D. from Politecnico di Torino in 1994.  He was a recipient of the AEI G.Someda Scholarship in 1991, has been with the European Space Agency (ESTEC, Noordwijk, The Netherlands) from May 1994 to February 1995,  was a recipient of the COTRAO Scholarship in 1996 and of a CNR Scholarship in 1997.  He has been visiting Princeton University in summer 1997 and Sydney University  in summer 2000.  He has been Assistant Professor in Telecommunications at the Politecnico di Torino, Associate Professor at the University of Parma, Italy,  Professor with the Department of Mobile Communications at the Eurecom Institute,  Sophia-Antipolis, France, and he is now professor with the EE Department of the Viterbi School of Engineering, University of Southern California, Los Angeles, CA. He served as Associate Editor for the IEEE Transactions on Communications in 1998-2001 and as Associate Editor for the IEEE Transactions on Information Theory in 2001-2003.  He received the Jack Neubauer Best System Paper Award from the IEEE Vehicular Technology Society in 2003,  and the Joint IT/Comsoc Best Paper Award in 2004.  Since November 2004 he is member of the Board of Governors of the IEEE Information Theory Society. His current interests are in the field of communications theory, information theory and coding theory with  particular focus on wireless applications.
