Abstract

Mobile edge computing (MEC) and non-orthogonal multiple access (NOMA) technologies play an essential role in improving computation diversity and spectrum efficiency. Considering the offloading requirements in both the near-and-far users, we firstly propose a delay-aware offloading scheme for cooperative NOMA-based near-and-far MEC networks. In the proposed scheme, the NOMA offloading is considered in both two cooperative stages to efficiently offload both users' computation tasks. Moreover, a delay minimization problem is formulated to optimally allocate the transmit power, time slot as well as the computation tasks. Numerical results show that the scheme proposed in this paper can efficiently reduce the information time delay of the system.
