A naming scheme to represent geographic areas in NDN

Abstract

Vehicular networks are intended to support a safer and more comfortable driving experience both through vehicleto-infrastructure communication and, even more interesting, vehicle-to-vehicle ad-hoc networking. In the latter case, the focus will be on getting a content of interest from a specific geographic region, rather than communicating to a predetermined host. As current IP-based protocols are specifically designed for conversations between hosts, innovative solutions have to be devised. To this aim, we consider the Named Data Networking paradigm and propose a named-data approach efficiently mapping bidimensional geographic areas into a uni-dimensional naming scheme.

VANET via Named Data Networking

“…Moreover, some applications may choose to encode location information in data names when the content concerns a limited area, such as traffic or parking data [7]. The location might then be used to help Interest forwarding [8].…”

“…In addition, one may desire to encode multi-dimensional information into names, for example ideally Info-Traffic data name should carry both location and time information. [7] does not fully solve these problems.…”

A Geographic Opportunistic Forwarding Strategy for Vehicular Named Data Networking

“…al. in [10] pointed that most vehicular applications focus on getting POI related information and proposed an approach to map bi-dimensional geographic areas into a uni-dimensional naming scheme to identify geographic areas related data. Yu et.al.…”

Hierarchical and hash based naming with Compact Trie name management scheme for Vehicular Content Centric Networks

“…Information Centric Networks (ICNs) [3][4][5]. 18 ICN has attracted the research community due to the capability of 19 overcoming the conventional IP/HOST based communications. The 20 main concept of ICN is to smoothly distribute digital contents be- 21 tween the content originator and the requesting node without con- 22 cerning the content originator's location or an associated IP address.…”

“…It is claimed that these 217 attributes will facilitate data requesting and producing nodes to eas-218 ily search and represent information in the VCCN. 219 In [19], the authors propose a hierarchical naming scheme for ve-220 hicular networks that solely aims to embed 2D geographical informa-221 tion. The main objective of the proposed naming scheme is to easily 222 retrieve cache hit ratio for the location information retrieval in VCCN.…”
