Abstract

The use of IEEE 802.11p for supporting intelligent transportation systems (ITS) enables enhancing the drive experience to provide vehicle users with useful information related to road efficiency and public safety. Safety services, such as collision or sudden hard braking warning, are used to improve passenger safety and reduce fatalities. Along with the delay-critical nature of those services, the highly dynamic communication environment of vehicular networks demand an efficient medium access control (MAC) protocol to assure minimal transmission collisions. This work-in-progress paper presents a preliminary study on the adequacy of existent 802.11p based MAC protocols regarding safety applications, and proposes ideas to implement such services in an effective way assuming an infrastructure based operation mode.
