Re: [ipwave] I-D Action: draft-ietf-ipwave-vehicular-networking-14.txt

Hi, all.

I reviewed IPWAVE draft and wrote down the humble comments.

---

#Clause 1.

At the third paragraph, my proposal is adding new reference,
[ISO-ITS-IPv6-Amd1].

“Along with these WAVE standards, IPv6 …

For Land Mobile (CALM) [ISO-ITS-IPv6], [ISO-ITS-IPv6-Amd1].

#Clause 2.

-New term, V2X should be added.

Generally speaking, vehicle-to-everything (V2X)  term is including V2I and
V2V.

So, new term should be define in Clause 2 (Terminology) with a sentence
excluding V2I and V2V use cases like a description of the first paragraph
of Clause 3. And this term should also include the V2P and V2D use cases.

-About Edge Network (EN),  “In” is changed to “It”.

-About IP-OBU,

This term is currently focused on a vehicle.

In case of a Device or Pedestrian, I want to know whether the IP-OBU
functionality is supported in them or not. I think this issue is solved in
this term.

-About Vehicle Detection Loop (i.e., Loop Detector),

This term is only used to define TCC in this document.

So, I think this term is useless.

#Clause 3,

-In Clause 3.1 V2V

In the first paragraph of Clause 3.1, these are four use cases of V2V
networking.

The second “cruise control” use case is described for urban environment.

The third “platooning” is also described for the highway.

So, I suggest that “in an urban roadway” and “in a highway” is redundant at
the second and third bullet  points.

-In Clause 3.1

In “Cooperative-environment-sensing” use case, describing the reward
system  is better. For more active cooperation, the supporter of
information should have   the benefit.

-In Clause 3.3 V2X

V2I2X is not described in upper part.

#Clause 4,

-In the fourth paragraph on page 12

We suggest like this;

“In the host-based mobility scheme, an IP-RSU plays a role of a home

  agent.”  We propose just deleting the “in a visited network”.

-In Clause 4.2 V2I-based Internetworking

In Figure 2, the internal network of Vehicle1 is constructed using wired
and wireless. So, the internal network of Vehicle1 should be changed
including two types of arrows (wired and wireless link) unlike EN1.

-In Figure 4,

It just comments. I think the Figure 4 can be used in Platooning
environment.

In that case, a Host has a role of leading vehicle with driver’s operation.
Others will be a driverless vehicles. So, star topology will be also used.

#Clause 6

-In the second paragraph of Clause 6,

“Also, in-vehicle devices (e.g., ECU) and mobile devices (e.g., smartphone)
in a vehicle need to …in another vehicle,”

I think that “mobile devices” can be existed out of the vehicle, just near
the vehicle. And the pedestrian also has them. So, this sentence should be
extended to include others such as pedestrian.

#Clause 7

[ISO-ITS-IPv6-Amd1]

ISO/TC 204, Intelligent transport systems - Communications access for

Land mobiles (CALM) - IPv6 Networking Amendment 1, September 2017.

Thanks.

Jungsoo, PARK
