Abstract: Energy Efficient Mobile Edge Computing for 5G and Beyond
Energy-efficient computation is an inevitable trend for mobile edge computing (MEC) networks. Resource allocation strategies for maximizing the computation efficiency are critically important. In this talk, computation efficiency problems are formulated in the MEC networks under both partial and binary computation offloading modes. A practical non-linear energy harvesting model is considered. Both time division multiple access (TDMA) and non-orthogonal multiple access (NOMA) are considered and evaluated for offloading. The local computing frequency, the offloading mode, the offloading time, and transmit power are jointly optimized to maximize the computation efficiency under the max-min fairness criterion. Moreover, the tradeoff is studied between the computation efficiency and the computation throughput. Performance results show that the partial computation offloading mode outperforms the binary computation offloading mode and NOMA outperforms TDMA in terms of computation efficiency.
