English abstract:
Abstract-IEEE 802.11p and the European profile standard
ITS-G5 define adjustments to the Physical Layer (PHY) and
Medium Access Control (MAC) of IEEE 802.11 for the support
of Intelligent Transport Systems (ITS). This includes ad hoc
communication links between vehicles as well as between vehicles
and roadside infrastructure. The MAC method of 802.11p uses
randomized backoff in the case of simultanious access attempts
which induces unpredictable communication delays. It is known
that such unpredictable delays severely limit the value of safetyrelated
services. The most effective way forward is to design a
protocol that suits vehicular traffic and safety-related service constraints.
Self-organizing Time Division Multiple Access (STDMA)
is a suitable alternative. Due to its predictable delay and periodic
character, it is suitable for scheduling time-triggered data, such
as Cooperative Awareness Messages (CAM). In this article we
outline new scenarios for STDMA, which will be the foundation
for further simulations and analysis.
