II-NEW: Versatile Hardware Emulator for ISM-band Network Management

实验研究在无线网络协议的开发中具有重要意义。虽然广泛使用的仿真方法的实验研究是很好的研究大规模的网络级的性能，模拟器不能代表真实的物理环境和硬件实现精确。另一方面，试验台方法可以解决仿真方法的真实性缺陷，但面临严重的可重复性和控制问题。使用无线仿真器是评估无线网络协议的最新趋势。仿真器可以实现高度的真实感和细粒度的可重复性。本项目开发了一个多功能的基于硬件的仿真器，支持在广泛的ISM频段无线网络（2- 6 GHz），包括IEEE 802.11 a/B/g/n，IEEE 802.15.4和蓝牙网络的可控，可重复和可扩展的实验。硬件仿真器是一种特别方便的研究工具，通过提供可控的干扰环境来研究ISM频段中的独特干扰问题。它可以在许多研究项目中进行实验研究，包括无线网络协议开发、干扰缓解技术和资源管理。 该项目将影响下一代无线网络的实施、评估和开发。本项目所设计的仿真器具有广泛的适用性，可以应用于许多商业和民用领域。模拟器还提供了一个自然的工具，用于教学使用，协助有效的课堂教学和归纳学习。

Experimental investigations are important in the development of wireless network protocols. While the widely used simulation approach for experimental investigations is good for studying large-scale network-level performance, simulators cannot represent the real physical environment and hardware implementation precisely. On the other hand, the testbed approach can address the realism drawback of the simulation approach, but faces serious repeatability and control issues. A recent trend on evaluating wireless network protocols is to use wireless emulators. Emulators can achieve both a high degree of realism and fine-grained repeatability. This project develops a versatile hardware-based emulator supporting controllable, repeatable, and scalable experiments over a wide range of ISM-band wireless networks (2-6GHz), including IEEE 802.11 a/b/g/n, IEEE 802.15.4, and Bluetooth networks. The hardware emulator is a particularly convenient research tool for investigating the unique interference issue in ISM bands by providing a controllable interference environment. It enables experimental investigations in a number of research projects, including wireless network protocol development, interference mitigation techniques, and resource management. This project impacts the implementation, evaluation, and development of next-generation wireless networks. The designed emulator from this project has general applicability to many commercial and civilian applications. The emulator also provides a natural tool for instructional use, assisting effective classroom teaching and inductive learning.
