Therefore, it will be mandatory to bring connectivity, computation and storage support at the edge of the network to limit service delay and both devices and network energy consumption. This is why 5G proposed architectures add Mobile Edge Computing (MEC) intelligence and elastic ad hoc distribute (multi)cloud support closer to the users. On the other hand, most of operations needed for services provisioning and network optimization are recurrent, context-dependent and too often re-executed. In this talk, we propose a novel paradigm, the computation caching for MEC, aimed at further reducing both power consumption and service delay of mobile edge cloud computing by caching popular computations, in order to prevent re-executing the same instruction blocks. Our proposal is based on merging computation caching with mobile cloud computing. To this end, we propose to use full storage potential of edge cloud clustering for computation caching. Exploiting the popularity of computational requests, some are cached at the edge of the network, preventing their recurrent computation. Simulation results show that our proposal permits to substantially reduce both energy an delay without degrading performance. Bio : Dr. Emilio Calvanese Strinati obtained his Engineering Master degree in 2001 from the University of Rome ‘La Sapienza’ and his Ph.D in Engineering Science in 2005 on Radio link control for improving the QoS of wireless packet transmission. He then started working at Motorola Labs in Paris in 2002. Then in 2006 he joint CEA/LETI as a research engineer. From 2007, he becomes a PhD supervisor. From 2010 to 2012, Dr. Calvanese Strinati has been the co-chair of the wireless working group in GreenTouch Initiative which deals with design of future energy efficient communication networks. From 2011 to 2016 he was the Smart Devices & Telecommunications European collaborative strategic programs Director. Since December 2016 he is the Smart Devices & Telecommunications Scientific and Innovation Director. In December 2013 he has been elected as one of the five representative of academia and research center in the Net!Works 5G PPP ETP. He is currently one of the three moderators of the 5G future network expert group. Since 2016 he is the coordinator of the H2020 joint Europe and South Korea 5G CHAMPION project. E. Calvanese Strinati has published around 100 papers in international conferences, journals and books chapters, given more than 50 international invited talks and keynotes and is the main inventor or co-inventor of more than 60 patents. He has organized more than 50 international conferences, workshops, panels and special sessions on green communications, heterogeneous networks and cloud computing hosted in international conferences as IEEE GLOBCOM, IEEE PIMRC, IEEE WCNC, IEEE VTC, EuCnC, IFIP, and European Wireless.
