Performance Evaluation of Inter-Vehicle Communications Based on the Proposed IEEE 802.11p Physical and MAC Layers Specifications

Traffic control, accidents prevention, vehicles au- tomation and useful services to the drivers have always been goals of an intelligent traffic system. With this objective, the IEEE is finalizing its new standard: the IEEE 802.11p, which defines the vehicular ad-hoc networks physical and medium access control layers characteristics. This paper presents simulations to evaluate the performance of these networks operating according to the new standard, at different scenarios, using the most recent version of the well-known network simulator NS-2. The results show that the transmissions quality impact is directly linked to dynamic changes in the network topology.
