Abstract

Abstract

In order to improve the security of Non-Orthogonal Multiple Access (NOMA) based Mobile Edge Computation (MEC) system when computation tasks are partially offloading, the physical layer security of MEC network in the presence of eavesdroppers is considered, and the security interruption probability is used to measure the security performance of computation offloading. Considering the transmit power constraint, local task calculation constraint and secret outage probability constraint, and then, the energy consumption weight factor is introduced to balance the transmission energy consumption and the calculated energy consumption. After that, the sum of system weighted energy consumption is finally achieved. In the case of satisfying two user priorities, to reduce the system overhead, a joint task offloading and resource allocation mechanism is proposed to archive the optimal solution of the transformed problem through an iterative optimization algorithm based on bisection search, and the optimal computing task offloading and power allocation are obtained. Simulation results show that the proposed algorithm can effectively reduce the energy consumption of the system.
