论文摘要
命名的数据网络(NDN)是一种最一流的体系结构,可通过Internet处理内容分布。随着视频流传输和未来大规模物品和车辆(IoT/IOV)流量的爆炸式增长,不断发展的Wi-Fi网络将在此类生态系统中发挥重要作用。但是,无线网络上的本地NDN部署可能表现不佳。 Wi-Fi广播/多播由于使用基本服务模式而导致吞吐量减少。尽管最近的初始著作解决了这一问题,但仍需要进一步的研究和建议来促进本地NDN的采用。我们主张,在无线网络上设计可行的本机NDN迈出的第一步应该是了解新兴方案中的挑战,并提供统一的基线来比较和提出建议。为此,首先,我们强调了一些挑战和方向,以提高吞吐量和能源效率,减少处理开销以及安全问题。接下来,我们提出了一个NDN的变体,该变体通过通过单播执行传输以避免无线网络中的风暴来最大程度地减少问题。最后,我们进行了性能评估,以将标准本机NDN与我们对Wi-Fi 6车辆网络的提案进行比较。结果表明,我们的提案在评估的方案中的表现优于标准NDN,达到了接近满足请求的89%的值,而收到的数据中的200%以上的数据比标准NDN达到了200%以上。
Named Data Networking (NDN) is a top-notched architecture to deal with content distribution over the Internet. With the explosion of video streaming transmission and future massive Internet of Things and Vehicles (IoT/IoV) traffic, evolving Wi-Fi networks will play an essential role in such ecosystems. However, Native NDN deployment over wireless networks may not perform well. Wi-Fi broadcasts/multicasts result in reduced throughput due to the usage of basic service mode. Despite recent initial works addressing that issue, further studies and proposals are required to boost the adoption of Native NDN. We advocate that an initial step towards designing a feasible Native NDN over wireless networks should be understanding the challenges in emerging scenarios and providing a uniform baseline to compare and advance proposals. To this end, first, we highlight some challenges and directions to improve throughput and energy efficiency, reduce processing overhead, and security issues. Next, we propose a variant of NDN that minimizes the problems identified by performing transmission via unicast to avoid storms in wireless networks. Finally, we conducted a performance evaluation to compare Standard Native NDN with our proposal on Wi-Fi 6 vehicular networks. The results show that our proposal outperforms the Standard NDN in the evaluated scenarios, reaching values close to 89% of satisfied requests, achieving more than 200% of data received than Standard NDN.
