In general, the typical structure of a
VANET is depicted in Fig.
Future work in this area is the implementation of the proposed protocol in a heterogeneous
VANET environment.

Applications for Vehicular Ad hoc Network (
VANET) ranges from road safety messages and traffic management to infotainment.

The unique
VANET characteristics of highly mobile vehicles, limited coverage area, intermittently wireless connection, and traffic density, in addition to restriction of movement within road patterns and traffic rules, make providing more reliable and efficient routing protocol for these challenging networks is still an open research topic; some of these recently related studies attend.
In [33], a Traffic Light Aware Routing (ETAR) protocol was proposed for
VANET. This protocol finds the most stable route for exchanging data packets based on traffic lights and traffic density of vehicles.
VANET is an application of mobile ad hoc networks (MANETs) which differs from MANETs in a few ways like the following.
To address these problems, we propose a traffic light control system using secure messages of vehicles in
VANET. A vehicle only sends anonymous messages to announce its presence to a traffic controller in a way that the movements of a vehicle are not tractable and the real identity is hidden from the vehicles.
In simulations the group model has been shown to be effective in achieving anonymity in
VANET communications but it is less effective the lower the vehicle density, since anonymity level depends on the number of vehicles in each group.
