Introduction
Currently, there are various technologies and protocols are either used and proposed for vehicle assist issues. Those technologies has some advantages along with some drawbacks individually. In this document, we discuss about those features and limitations of those technologies. Concurrently, the existing challenges in the development progress of them also discuss at the end of the document. Optical camera communication (OCC) is able to overcome the existing limitations.

Features of Vehicular Assistive Technology
The technology use wireless channel with massive connected nodes.
Delivering information from one vehicle to another vehicle to make fast decision.
The encoding and modulation scheme must applicable in all speed scenarios (e.g., 110 km/h)
The technology should be cost effective and modify little bit the whole infrastructure for vehicle environment.
The position node as well as the network topology will change frequently due to varying speed of vehicles.
All supporting infrastructures will inter-connect with each other and simultaneously assist the vehicle during the demand.

Limitations of Vehicular Assistive Technology (1/2)
On the basis of MAC protocol
Protocol
Limitations
IEEE p
Quality-of-service is deteriorate in real traffic scenarios.
ADHOC MAC
Fixed slot number.
VC-MAC
Communication between certain nodes is limited.
MP-MAC
Multi-hop communication is impossible.
DMAC
It is failing without the information about geographic position.

Limitations of Vehicular Assistive Technology (2/2)
On the basis of routing protocol
Routing protocol
Limitations
Connectivity-aware routing
Depends on previous data and average velocity of vehicle.
Instant messaging services
The maximum distance between host vehicle and other vehicle has an impact of making instant decisions.
Caching geocast
Network partition has an affect on it.
Urban multi-hop
broadcast protocol
Performance is deteriorate during less traffic scenario.
Inter-vehicle geocast
Depending on Global Positioning System (GPS).
Greedy perimeter stateless routing
It is a direct communication protocol.

Challenges in Vehicular Assistive Technology
Challenges:
There are several obstacle that is in front of autonomous vehicle authentication processes. Moreover, this is delayed due to numerous reason; privacy is important among them.
This type of network should be fully available for real-time applications.
Without the precise solution, it will bring serious damage rather than current conditions.
It’s performance will be constant in any speed of the vehicles especially high speed.
It may mitigate the interference from other similar technologies.
