Comparison of position based routing protocols of vehicular Ad Hoc network

The vehicular Ad hoc network is a distinguish approach for intelligent transportation system and a sub class of mobile Ad hoc network. The emergence of wireless communication and transportation through inter vehicular communication has promised countless applications enhance the overall driving experience. Vehicular communication would require efficient routing protocols, secure communication, proper coverage and standards. Various routing protocols have been adapted for VANET and particularly using position based routing approach. The paper gives an overview of position based routing protocols and compare them in the context of driving experience and safety.
