Abstract
Due to multi-lanes, speed limit, buildings around corners and traffic lights, Vehicular Ad Hoc Networks (VANETs) with urban areas especially in intersections have more complicated network topology, resulting in standard flat routing protocols inapplicable in VANETs. Theoretically hierarchy based routing protocol such as CBRP (Clustering Based Routing Protocol) can achieve better performance in VANETs. To the best of our knowledge, there is no literature reporting network performance tests on CBRP in VANETs. Existing Network Simulator (NS) does not contain CBRP, therefore this paper firstly implements CBRP into NS-2.35 and then aims to compare and analyze performance of CBRP against AODV (Ad Hoc On-demand Distance Vector) and DSR (Dynamic Source Routing) in VANETs based on IDM-IM (Intelligent Driver Model with Intersection Management) modeled by VanetMobiSim. Simulation results reveal that CBRP performs well compared to AODV and DSR in terms of delay, packet loss ratio and route costs.
