Traffic modeling of safety applications in Vehicular Networks

Abstract

Workload modeling is one of the main methods for analysis the performance and capability of service provider systems. Widespread usage of workload modeling in computer networks has made it a critical necessity. Vehicular ad hoc Network (VANET) are computer networks established among the moving vehicles on a highway or street. Since these networks are still in the assessment phase and has not reached the commercial implementation, scrutinizing the workload of defined programs for such network is a must. So we can evaluate its performance in real situation and do any further consideration before deployment phase. This research provides a mathematical model for workload of these networks and compares the obtained results with the simulation made in the standard context of 802.11p in OMNeT++ simulator and the Graphical User Interface of mathematical model has been made in Matlab platform. One of the prerequisites for analyzing workload generator applications in these networks is providing an appropriate classification, according to mathematical model requirements. Comparing the obtained result of simulation and mathematical model demonstrates a good accordance between them.
