Comparison of topology based protocols of vehicular ad hoc network

Vehicular Ad hoc network is a new and most useful technology for transportation services. Still this technology has been facing various issues and challenges. One of the major challenges is efficient routing between vehicles for solving the disconnectivity, delay, obstacles and high mobility issues in highway and metropolitan areas. Many types of protocols working for routing and play their significant role in different angels. The topology-based protocols are one of the major categories in routing taxonomy. In this paper, we compare popular topology based routing protocols and their comparison with each other.
