Caching, i.e. storing popular contents at caches available at end users, has received a significant interest as a technique to reduce the peak traffic in wireless networks. In particular, coded caching proposed by Maddah-Ali and Niesen has been considered as a promising approach to achieve a constant delivery time as the dimension grows, yielding a scalable system. Albeit conceptually appealing, several limitations prevent its straightforward applications in practical wireless systems. We address the limitations of classical coded caching in various wireless channels. Then, we propose novel delivery schemes that exploit opportunistically the underlying wireless channels while preserving partly the promising gain of coded caching.


Asma Ghorbel graduated from (SUP’COM) Higher School of Communication of Tunis in Tunisia and from Télécom ParisTech in France in 2014. She is currently pursuing a Ph.D. on coded caching in wireless networks at Centrale-Supélec in France.
