论文摘要
移动边缘计算（MEC）是一种旨在减少延迟的新兴通信方案。在本文中，我们研究了窃听者存在下的绿色MEC系统。我们使用计算效率，该计算效率定义为计算的位总数除以总能量消耗，为我们的主要指标。为了减轻严格的延迟要求，提出了联合安全的卸载和计算模型。此外，我们在几个实际的约束下制定了最大化计算效率的优化问题。连续的凸近似和迭代算法解决了非凸问题。仿真结果验证了我们提出的方案的优势以及我们的问题解决方案的有效性。
Mobile edge computing (MEC) is an emerging communication scheme that aims at reducing latency. In this paper, we investigate a green MEC system under the existence of an eavesdropper. We use computation efficiency, which is defined as the total number of bits computed divided by the total energy consumption, as our main metric. To alleviate stringent latency requirement, a joint secure offloading and computation model is proposed. Additionally, we formulate an optimization problem for maximizing computation efficiency, under several practical constraints. The non-convex problem is tackled by successive convex approximation and an iterative algorithm. Simulation results have verified the superiority of our proposed scheme, as well as the effectiveness of our problem solution.
