Study of efficient topology based routing protocols for vehicular Ad-hoc network technology

The expansion in Ad-hoc wireless network and vehicular Ad-hoc networks, it is expected that traffic data will be collected and dispersed in real time by mobile sensors as a alternative of fixed sensors infrastructure. Routing in vehicular Ad-hoc networks is a challenging field of interest, due to high speed and city environment. Recently, there have been a number of broadcasting protocols for VANETs and categorized with the topology, position and network based. We categorize Topology based routing protocols into three types reactive, proactive and hybrid protocols. We survey state of the art vehicular Ad-hoc network types and then discuss topology based routing protocols and their characteristics. We discuss Advantages and Disadvantages for topology based routing protocols. The main mean of our paper was to categorize topology based routing protocols and comparison with each other.
