Abstract
Intelligent transportation systems (ITS) witnessed a great progress through developing new communication applications based on cooperative approach. These applications need a crucial QoS (Quality Of Service) performance and effectiveness. High precision is an eligible condition for ITS safety applications because they are characterized by a real time transmission via cooperative system information. In this paper, we propose a multi-application module for VEINS simulator in order to realize a realistic and dynamic simulation model for performance evaluation of safety and non safety applications on multi-channel operations compared to the single channel operation. Then, we analyze performance of safety and non-safety messages dissemination model for the four EDCA class of the IEEE 1609.4 standard. Our simulations confirm QoS differentiation of IEEE 1609.4 standard and it shows influence of high traffic density on QoS performance.
