Abstract

The investigation of infrastructureless safety applications in different transportation systems is a hot research topic. The nodes in the network are designed to advertise to the rest of the nodes informationa-bout the current traffic situation by means of short beacon messages containing speed, direction, positions and other relevant safety information. The scheduling should be organized by the MAC layer so that the transmitted messages arrive successfully as soon as possible at the receiver. The networks that support these kind of applications are Mobile Ad-hoc Multibroadcast Networks (MAMNETs). In this paper we present the challenges the MAC layer for MAMNETs should overcome. We discuss the most important performance metrics of the MAC layers in order to obtain a system independent analysis and show a survey of the factors that may influence the behavior of the MAC layers.
