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

开源网络仿真（ns-3）工具被研究人员广泛用于评估计算机网络的性能。在过去十年中，用户对新的ns-3功能的需求集中在模拟快速新兴的无线网络技术，包括无线保真（WiFi）和长期演进（LTE）蜂窝系统。新功能对于探索新兴的第5代（5G）蜂窝网络技术至关重要。该项目旨在1)扩展ns-3的核心无线功能，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；3)更好地将ns-3与无线网络试验台的实验结合起来。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先进无线研究平台（PAWR）城市规模的先进无线基础设施测试平台。异构网络的新无线技术共存场景以及由于网络致密化导致的持续扩展挑战是这项工作的主要研究重点。此外，一个关键的项目目标是改进新的ns-3教材的可用性和开发，以便下一代用户更容易地采用这些新模块（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电信技术中心（CTTC巴塞罗那）研究人员之间的现有合作。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值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.
