FIT/CorteXlab Experiment examples Links with R2Lab Conclusion Wireless Caching Collaboration with Nokia Bell Labs New Jersey and U. of Naples Objective: combine wireless caching in 5G Networks and coded multicasting to serve multiple unicast demands. Motivation: wireless users rarely access the same content at the same time We evaluate on a prototype implementation the experimental performance of state-of-the-art caching-aided coded multicast schemes compared to state-ofthe-art uncoded schemes To be published in IEEE communications magazine Tanguy Risset FIT/CorteXlab - INRIA/Insa-Lyon 22
