论文摘要
在本文中，我们提出了一个增强的基于序言的媒体访问控制机制（E-PMAC），该机制可用于工业互联网（IIOT）的电力线通信（PLC）网络（IIOT）。我们介绍了E-PMAC中使用的详细技术，包括延迟校准机制，序言设计和插槽分配算法。使用这些技术，E-PMAC比现有的基于序言的MAC机制（P-MAC）更强大。此外，我们分析了多层网络中P-MAC的缺点，并设计了E-PMAC的网络过程以加速网络过程。我们分析了P-MAC和E-PMAC中网络过程的复杂性，并证明E-PMAC的复杂性低于P-MAC。最后，我们模拟了E-PMAC，P-MAC和现有PLC协议的单层网络和多层网络，即IEEEE1901.1。仿真结果表明，与IEEEEEEEEE1901.1和P-MAC相比，E-PMAC在网络上的时间少得多。最后，通过我们的工作，可以实现基于E-PMAC机制的PLC网络。
In this paper, we propose an enhanced preamble based media access control mechanism (E-PMAC), which can be applied in power line communication (PLC) network for Industrial Internet of Things (IIoT). We introduce detailed technologies used in E-PMAC, including delay calibration mechanism, preamble design, and slot allocation algorithm. With these technologies, E-PMAC is more robust than existing preamble based MAC mechanism (P-MAC). Besides, we analyze the disadvantage of P-MAC in multi-layer networking and design the networking process of E-PMAC to accelerate networking process. We analyze the complexity of networking process in P-MAC and E-PMAC and prove that E-PMAC has lower complexity than P-MAC. Finally, we simulate the single-layer networking and multi-layer networking of E-PMAC, P-MAC, and existing PLC protocol, i.e. , IEEE1901.1. The simulation results indicate that E-PMAC spends much less time in networking than IEEE1901.1 and P-MAC. Finally, with our work, a PLC network based on E-PMAC mechanism can be realized.
