With the exponential growth of mobile devices in 5G network, massive content delivery in a cellular network is the upcoming challenge for researches. Due to large data traffic, energy efficiency becomes increasingly important as well as the user throughput requirement increases. In this paper, we propose Network-coded Cooperative (NCC) communication on virtualized Mobile Small Cells (MSCs) to minimize energy consumption on MSCs realizing the benefits of Mobile Edge Computing (MEC). The proposed approach adopts MEC and Software Defined Networking (SDN) to evaluate the gains in terms of user throughput that can be achieved when data contents are moved from cloud to the edge of the Radio Access Network. Moreover, the data contents are transferred to user equipments (UEs) in a cooperative approach to reduce the energy consumption in MSCs. The evaluation results show a decrease in the energy consumption per UE of 62% for the best case, due to a decrease of the LTE channel usage in favor of WiFi, which consumes less energy.
