A Comparative Study Cluster-Based Routing Protocols in VANETs for City Environment

Vehicular Ad-hoc Networks (VANETs) is consid-ered as an extension of Mobile Ad-hoc Networks (MANETs) which the vehicles have high mobility on the street and in-termittent connectivity. The vehicles move on the street and communicate with each other to share the information such as traffic information, road condition, warning message at the corner, and browsing the internet at the car's backseat, etc. Because of the quick speed of vehicles and intermittent connectivity that making routing protocol plays a significant role in VANETs to deliver the packets among the nodes. There have bio-inspired routing protocols and traditional routing protocols, as well as mobility models, are proposed to obtain an optimal solution for this challenge. In this paper, we illustrate the essential information about the cluster-based technique in VANETs and do a comparative study on cluster-based routing protocols between ACO and AODV, and its mobility for the city environment.
