2. Introduction

3. Introduction InVANET is an Intelligent Vehicular Ad Hoc Networking
uses WiFi IEEE and
WiMAX IEEE
for easy and effective communication between vehicles with dynamic mobility.

4. Introduction VANET, is a form of Mobile ad-hoc network,
to provide communications among nearby vehicles and
between vehicles and nearby fixed equipment, usually described as roadside equipment.
In intelligent vehicular ad hoc network, rather than moving at random as in MANET vehicles tend to move in an organized fashion.

5. Introduction Providing
vehicle-to-vehicle and
vehicle-to-roadside communication
can considerably improve traffic safety and comfort of driving and traveling.

6. Introduction
Each vehicle equipped with VANET device will be a node in the Ad-Hoc network and can receive and relay others messages through the wireless network.
Each node in the ah-hoc network functions as the router to another node.
The terminals act like repeaters that relay the information packets flying back and forth about the ad-hoc network from one mobile terminal to the next.

7. Mobile IPv6 Mobile IPv6 is a widely accepted solution
to provide session continuity and
reachability to the Internet for mobile nodes.

8. Mobile IPv6 Mobile IPv6 proxy-based architecture
selects the optimal communication mode
direct in-vehicle,
vehicle-to-vehicle,
and vehicle-to-roadside communication
provides dynamic switching between
vehicle-to-vehicle and
vehicle-to-roadside communication mode

9. Model for InVANET

10. Goal of InVANET
The main goal of VANET is to provide safety and comfort for passengers.
Communication between vehicles can be used
to realize driver support and active safety services like
collision warning,
up-to-date traffic and
weather information or
active navigation systems.

11. Examples There are also
multimedia and
internet connectivity facilities
for passengers, all provided within the wireless coverage of each car.
Automatic payment for parking lots and toll collection are other examples of possibilities inside VANET.

12. Characteristics
Lack of pre-configuration, meaning network configuration and management must be automatic and dynamic.
Node mobility, resulting in constantly changing network topologies.
Multi-hop routing.

13. Characteristics
Resource limited devices, e.g. laptops, PDAs and mobile phones have power and CPU processing constraints.
Resource limited wireless communications, e.g. reduced to 10's of kilobits per second by the fact that many nodes must share the radio medium.
Potentially large networks, e.g. a network of sensors may comprise thousands or even tens of thousands of mobile nodes

14. Advantages
Inter-vehicular communication services such as intersection collision warning, local danger warning, and the de-central dissemination of real-time traffic flow information.
The mobile terminals not only provide a function for information transmission and reception but also provide a function for information relay i.e. provides the function of router.
Ad-hoc network provides anytime, anywhere access environment.

15. Challenges Scability of protocol Introduction of Security
High-Speed Real-Time Communication

16. Scenario

17. Scenario
Several actors involved in inter – vehicular ad hoc network are:
The drivers, which benefit from the system by receiving warning messages and route recommendations.
Road operators, who receive traffic data and are therefore enabled to control the traffic in a more efficient way.
Hotspot and Internet service providers, who can attach vehicle communication systems e.g. at gas stations.

18. Scenario – Safety use cases
Cooperative Forward Collision Warning
Pre-Crash Sensing/Warning
Hazardous Location V2V Notification

19. Scenario – Traffic Efficiency use cases
Enhanced Route Guidance and Navigation
Green Light Optimal Speed Advisory
V2V Merging Assistance

20. Scenario – Infotainment and Others use cases
Internet Access in Vehicle
Point of Interest Notification
Remote Diagnostics

21. Technical Prerequisites and Constraints
Anonymity and Data Security
Effective Protected Frequency Band
Scalability
Mandatory Sensor Data

22. Architecture two approaches can be taken. Layered Approach and
Un-layered Approach

23. protocols fulfill small, well-defined tasks and
Layered Approach
protocols fulfill small, well-defined tasks and
form a protocol stack

24. Un-layered Approach All application and communication protocols
are placed in one single logical block

25. Research efficient message dissemination, network scalability, and
information security mechanisms

26. Conclusion
In InVANET, vehicles can communicate with the roadside communication infrastructure and also among each other.
A vehicle is not only information source or sink, but also information distributor.
The communication services enable a wide range of applications, ranging from road safety and traffic efficiency, driving comfort and infotainment.

27. Conclusion

28. Question 1
In Intelligent Vehicular AdHoc network (InVANET), vehicles are enabled to communicate among themselves i.e. V-2-V. It is explained that V-2-V enables communication for small to medium distances and at locations even where roadside access points are not available. Are we assuming that all the vehicles on the road will be equipped with communication/networking capabilities? If not, how realistic is InVANET?

29. Question 2
Vehicles move in certain speeds. We have roads or highways which have various speed limitations. Does InVANET impose any restriction on the speed of a vehicle for its smooth operation?

30. Question 3
The basic safety message spreading in a vehicular network consists of event warning message. But there are scenarios when message need to be delivered to specific areas example, to the end of a traffic jam queue so that arriving vehicles have the option of taking another route before getting stuck. How can the vehicular network support the secure routing?
any two nodes that wish to communicate securely can simply establish a priori a shared secret, to be used by their routing protocol modules.

31. Question 4
Is the network expandable? How did the cars in the network and the terminals maintain the flow control in the network?
External Management – external management plane symbolizes a configuration interface to set long-term system settings.
