Mobility model based on social network concept for VANETs

Mobility

Vehicular Ad-Hoc Networks (VANET) are a particular type of wireless adhoc networks. They are formed when equipping vehicles on the roads with short range wireless communication devices. Validation of mobile ad hoc network protocols relies almost exclusively on simulation. The value of the validation is, therefore, highly dependent on how accurate the movement models used in the simulations are. However, most widely used models are currently very simplistic, their focus being the ease of implementation rather than soundness of foundation. Therefore, simulation results of protocols are often based on randomly generated movement patterns and, therefore, may differ considerably from those that can be obtained by deploying the system in real scenarios. In this we propose a new mobility model based on the social network theory. The mobility model creates movement pattern by taking into consideration the social relationship among the individuals, social relationship that might change depending on the simulation time. We also present the results obtained in validating our model using the realistic vehicular traces.
