Abstract
Vehicular Ad Hoc Network (VANET) is becoming an important technology which col-
laborating ad hoc network, wireless LAN (WLAN) and cellular technology to attain
intelligent communication mechanism. Due to rapidly changing topology, obstacles in
communication network and limited mobility in VANET, there is a need of intelligent and
e cient routing protocol which promise improved e ciency in terms of minimizing delay,
increase throughput and reliability. A review of most recent protocols is presented by
using few parameters of the network, location veri cation, clustering, routing technique,
delay, control overhead and forwarding strategy. The review discusses the advantages
and disadvantages of routing protocols for vehicular ad hoc networks. It inspects the
need behind the design of these routing protocols. The review also includes Physical
layer and MAC protocol structure for current vehicular ad hoc networks. Finally the
review concludes discussing issues with routing protocol and Physical layer and MAC
protocol with regard to VANETs.
