论文摘要
本文提出了在设备到设备（D2D）通信设置和研究相关问题中的移动管道计算概念，其中D2D可能基于5G移动通信中的毫米波（MMWave）。拟议的机会系统采用了一组管道的资源有限设备来处理实时现场计算密集型任务，而当前的云计算技术可能不合适。随着高速和低延迟无线技术的成熟，这种系统的可行性可以预期。我们通过在系统级和管道设备级别上定义体系结构，基本功能，过程来提出系统模型。开发了管道探路算法以及多任务优化框架。为了最大程度地减少搜索空间，因为可能需要在资源有限的移动设备上运行该算法，因此建议使用仿真提出并验证了基于邻接的基于基准的图形修剪技术。使用实验和计算机模拟对我们提出的技术进行初步可行性评估。作为可行性评估的一部分，分析并检查了MMWave阻塞对管道稳定性的影响，并检查单层线和同时 - 二流线方案。我们的设计和分析结果为指导系统设计提供了一定的见解，并为在此行中的进一步工作奠定了基础。
This paper proposes a mobile pipeline computing concept in a Device-to-Device (D2D) communication setup and studies related issues, where D2D is likely based on millimeter-wave (mmWave) in the 5G mobile communication. The proposed opportunistic system employs a cluster of pipelined resource-limited devices on the move to handle real-time on-site computation-intensive tasks for which current cloud computing technology may not be suitable. The feasibility of such a system can be anticipated as high-speed and low-latency wireless technologies get mature. We present a system model by defining the architecture, basic functions, processes at both system-level and pipeline device level. A pipeline pathfinding algorithm along with a multi-task optimization framework is developed. To minimize the search space since the algorithm may need to be run on resource-limited mobile devices, an adjacency-matrix-power-based graph trimming technique is proposed and validated using simulation. A preliminary feasibility assessment of our proposed techniques is performed using experiments and computer simulation. As part of the feasibility assessment, the impact of mmWave blockage on the pipeline stability is analyzed and examined for both single-pipeline and concurrent-multiple-pipeline scenarios. Our design and analysis results provide certain insight to guide system design and lay a foundation for further work in this line.
