Performance evaluation of spider mobility model using AODV for VANET

Abstract

This paper presents a simulation study of Spider Mobility model on the performance study of VANET that uses Ad-hoc OnDemand Distance Vector (AODV) as the routing protocol. It is a crucial factor in the performance evaluation of VANET. When communication
and mobility are clearly separated. Spider mobility model has been widely used in the simulation study of VANET. Vehicle movement and traffic flow is the main area of concern during the simulation process under this paper. Usually drivers do not know which path to follow when any congestion or collision occurs. This simulation will suggest and will give glimpse to drivers under notification that the road they are choosing to travel will be safer and optimal path or not according to the priority of roads defined during road topology adopted. We carried out simulation on visualization tool named, SUMO, which shows the alternative paths by driver when congestion occurred. The traffic remains under flow only when no collision occurs, but vehicles choose different path when collision occurs. We noticed the collision reports for various road topology and parameters to define road map and vehicle movement. The results show that mobility model is not different in case each MN is moving at human running speed. Therefore, it is suggested to use Spider
mobility model because of its less computational overhead. Therefore, Spider mobility model should be used instead. Moreover, different levels of randomness setting have no effect on the accuracy of throughput and end-to-end delay.
