Vehicular ad-hoc network (VANETs) developed based on mobile ad hoc networks (MANETs), which is expected to provide communication between the vehicles and can be used for safety and entertainment applications for drivers and passengers. VANET have characteristics somewhat different from the MANET, the VANET mobile node moves faster, the number of nodes is more, topology changes very dynamically. Previous research shows that the model of mobility affecting network performance. An example of mobility model that is used to illustrate the movement of the mobile node is Gauss-Markov mobility model, which is used to illustrate changes of acceleration, velocity, and location, as well as its direction at any time. The contribution of this paper is the evaluation of the performance of Gauss-Markov mobility model on VANET, by evaluating various network performance metrics, particularly, packet delivery ratio, throughput, and delay use simulation software ns-3. This simulation was performed with the number of nodes and randomness index (a) that varies. From simulation results, there is a strong correlation between the decline in the value of Packet delivery ratio (PDR) and throughput with the addition number of MNs and also between the increase of delay and the addition number of MNs. In Gauss-Markov mobility model, the different value of alpha has no impact on PDR, Throughput, and delay.
