If the RSU is mobile, and even in the absence of RSU participation, 'how to authenticate the vehicle', will become a huge challenge of VANET
in the future.
One approach for traffic-light optimizing is the Shortest-Path-Based Traffic Light-Aware Routing (STAR) protocol for VANETs
As safety applications involve human lives, designing an appropriate, efficient and accurate trust framework remains a major concern and one of the most important challenges to be able to build cooperative safety applications in VANETs
However, recent development shows that more and more VANET
studies are including more vehicles and covering wider region   .
The BSM is the fundamental building block of VANET
safety systems, and the fundamental privacy vulnerability addressed by the privacy protocols evaluated in this research.
CL-PKC is considered to be well suited for VANETs
in perspective of limited bandwidth and the dynamic nature of such networks.
Con la aparicion de los modelos de movilidad surgieron diversas investigaciones en redes VANET
Many works are proposed to provide efficient routing protocols for VANET
to send the data quickly from the source to the destination [3, 11, 12].
Vehicular Ad Hoc Networks are considered as an extension of Mobile Ad Hoc Networks [MANETs]; in a VANET
each vehicle is a node of the wireless network, equipped with On- Board Unit [OBU].
The main component for success of VANET
applications is its routing.
Performance evaluation of DYMO has been carried out in VANET
scenarios and contrasted with traditional DSR and AODV.
RSU increases the coverage of VANET
and connects OBU with infrastructure.
