Asymmetric Framework Evolution of Named Data Networking and Use Cases in VANET
Jiangtao Luo, Lianglang Deng, Junxia Wang, Yongyi Ran · 2020
Named data networking (NDN) has been invented for a decade and has found lots of potential applications. It has also been extensively researched and regarded as one of the most promising architectures of the future Internet. However, at the same time, more and more work noticed its deficiency in time-sensitive applications or under complex scenarios such as vehicular ad-hoc networks (VANET), mainly due to its request-response communication model and binding of Interest and Data path. To address that, in this paper, an asymmetric framework, called aNDN, is proposed to evolve the architecture of NDN, which features decoupling the forwarding of Interest and Data packets as well as supporting both PULL and PUSH models. Furthermore, three basic use cases of aNDN in VANET were conducted, demonstrating its advantages in data transfer efficiency. More importantly, this work first calls for substantial evolution of NDN to fulfill much broader requirements from current and future emerging applications.
