TCP/IP protocol gradually exposes many shortcomings such as poor scalability and mobility. Content-Centric Networking is a new architecture which cares about the content itself rather than its source. Therefore, this paper proposes a novel IoV architecture which based on Content-Centric Networking and tests its transmission interference time, transmission delay, and throughout in network layer. The experimental results show that the novel architecture is superior to the current IoV in the communication performance.

1 Introduction
As a key member of the Internet of Things (IoT), Internet
of Vehicles (IoV) will greatly change the future life [
1
].
IoV turns each participating vehicle into a mobile node
and make vehicles connect to each other; hence, it creates
a network with a wide range. The basic types of IoV
communications could be divided into Vehicle to Vehicle
(V2V) communications and Vehicle to Road (V2R)
communications [
2
]. With On-board Unit (OBU) and
Roadside Unit (RSU) as network nodes, IoV enables
vehicles to transmit data in a single hop or multi-hop [
3
].
OBU is used as the network terminal node to transmit
information toward other OBU and RSU. RSU which
deploys along the road is the fixed node in V2R
communications [
4
]. OBU links with local Internet service provider
through RSU, so it can visit remote Internet server.
Therefore, RSU plays a role of gateway in IoV.
To achieve many outstanding functions such as
intelligent traffic management, intelligent vehicles control, and
dynamic information service, IoV needs to meet
following basic communication requirements [
5
]: (1) relatively
low communication delay, (2) sufficient transmission
distance, and (3) high reliability under high-speed
mobile environment. Meanwhile, the network topology
of IoV is complicated and changes rapidly, the time of
duration of communications link is short, and the
moving range of nodes is broad [
6
]. The current IoV
which mainly adopts IEEE WAVE protocol stack,
deploys TCP/IP protocol on transport layer and network
layer to be compatible with IP network [
7, 8
]. Compared
with other wireless communication technique, WAVE
already has excellent communication performances such
as low transmission delay (0.0002 s), long transmission
distance (1000 m), and high transmission rate (27 Mbit/s)
[9]. But because of basing on IP address, WAVE could not
support the mobility well. Continuously, changes in the
network topology will cause frequent reallocation of IP
address and make current IoV architecture not applicable
to communication scenarios which focus on the content
itself rather than its provenance [
10, 11
]. So, it is urgent to
find a revolutionary solution to build a new architecture
of IoV which can response to the development better [12].
Therefore, a novel architecture of IoV named CCN-IoV
was firstly proposed. Compared with IP network, CCN-IoV
located the content chunks of CCN in network layer,
fundamentally changes the traditional end-to-end
transmission mode, and improves mobile
communication performance of IoV. Then, the paper develops
experimental measurements for the network layer to
find transmission interference time, transmission
delay, and throughout under different application
scenarios. Experimental results show that CCN-IoV
has better communication performance.
The other parts of the paper are as follows: the
second section introduces CCN, the third section
presents CCN-IoV in detail, the forth section evaluates
the performance of CCN-IoV, and the last section is
the conclusion.
2 Content-Centric Networking
Aiming at the deficiency of IP network, Van Jacobson
put forward Content-Centric Networking (CCN) in
2009. Different from the IP network, CCN is
contentoriented, no longer focuses on interface address or host
location information [
13
]. So, CCN fundamentally
changes the IP package structure as well as addressing
mode. What is more, CCN has characteristics of short
transmission delay, low power consumption, and high
reliability, so it can fully respond to the future
development of mobile Internet [
14
].
