Abstract Vehicular Ad Hoc Network (VANET) is an emerging new technology integrating ad
hoc network, wireless LAN (WLAN) and cellular technology to achieve intelligent inter-
vehicle communications and improve road traffic safety and efficiency.. In these networks,
vehicles communicate with each other and possibly with a roadside infrastructure to provide
a long list of applications varying from transit safety to driver assistance and Internet access.
In these networks, knowledge of the real-time position of nodes is an assumption made by …

Vehicular Ad hoc Network (VANET) is a special type of Intelligent Transport System (ITS),
The design of routing protocols in VANETs is important and necessary issue for support the
smart ITS. The key difference of VANET and MANET is the special mobility pattern and
rapidly changeable topology. Existing routing protocols of MANET are not suitable for
VANET. This paper proposes SD-AOMDV as VANET routing protocol. SD-AOMD improves
the most important on demand multipath routing protocol AOMDV to suit VANET …
