Selection of Repetition Codes for MAC in Vehicular Ad Hoc Networks

Free registration required

Executive Summary

In the context of vehicular safety and entertainment applications, the authors focus on the design of a reliable medium access control scheme. Each vehicle is willing to form a network and regularly communicate with the other vehicles in its vicinity, forming a Vehicular Ad hoc NETwork (VANET). The information that is being communicated is short lived, and requires a very low probability of failure. In this paper they assume that there is no central entity managing the medium access for the cluster of vehicles. Several code-based repetition-based QoS provisioning MAC schemes have been proposed for this scenario.
