ICE-T: RC: Performance Evaluation of Advanced Wireless Network Edge Infrastructure - Network Simulation & Test Beds

开源网络仿真工具ns-3被研究人员广泛用于评估计算机网络的性能。在过去的十年中，用户对新的ns-3功能的需求主要集中在模拟快速崛起的无线网络技术，包括无线保真(WiFi)和长期演进(LTE)蜂窝系统。新的能力对于探索新兴的第五代(5G)蜂窝网络技术至关重要。本项目寻求1)扩展ns-3的核心无线能力，将模拟器定位为5G无线网络模拟的首选研究工具；2)提高可用性并创建新的教育/培训材料；以及3)更好地使ns-3与无线网络试验台上的实验保持一致。后一个项目目标预计将有助于最近宣布的国家科学基金会资助的高级无线研究平台(PAWR)城市规模的高级无线基础设施试验台。针对异类网络的新的无线技术共存场景以及由于网络密集化而带来的扩展的持续挑战是这一努力的主要研究推动力。此外，一个关键的项目目标是改进新的ns-3教育材料的可用性和开发，以便于下一代用户采用这些新的模块(以及更广泛的ns-3)。该项目扩展了华盛顿大学和加泰罗尼亚技术电信中心(CTTC巴塞罗那)研究人员之间的现有合作。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The open source network simulation (ns-3) tool is used widely by researchers to evaluate the performance of computer networks. Over the past decade, user demand for new ns-3 capabilities has centered on simulating rapidly emerging wireless networking technologies including Wireless Fidelity (WiFi) and Long Term Evolution (LTE) cellular systems. New capabilities are essential for exploration of emerging 5th Generation (5G) cellular network technologies.This project seeks to 1) extend the core wireless capabilities of ns-3, positioning the simulator as the research tool of choice for 5G wireless network simulations; 2) improve usability and create new educational/training materials; and 3) better align ns-3 with experiments on wireless network test-beds. The latter project goal is expected to contribute to recently announced National Science Foundation-funded Platforms for Advanced Wireless Research (PAWR) city-scale advanced wireless infrastructure testbeds. New wireless technology coexistence scenarios for heterogeneous networks as well as the ongoing challenge of scaling due to network densification are main research thrusts for this effort. In addition, a key project goal is improving usability and development of new ns-3 educational material to ease adoption of these new modules (and ns-3 broadly) by the next generation of users. The project extends an existing collaboration between investigators at the University of Washington and the Centre Technologic Telecomunicacions Catalunya (CTTC Barcelona).This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
