We argue that the rather predictable link quality between sender and receiver pairs in a platoon make acknowledgements redundant. Boukerche et al.  describe a protocol to estimate the reliability of unicast links in a VANET and use that knowledge to group those links into QoS classes. As in our work, no acknowledgements are needed to achieve this classification. Boukerche et al. do however not make use of retransmissions to boost the success ratio of packets over a certain link. While our proposed retransmission algorithm attempts to improve the packet reception probability through unicast retransmissions based on channel estimation, other studies are concerned with enhanced reliability by making the first transmission more likely to succeed.
Due to the particularly strict requirements on status exchange within a platoon, we argue that simple periodic broadcast on the common control channel (shared with other vehicles within the platoon’s radio range) is not a viable option. We therefore suggest the use of a dedicated service channel (SC) for intra-platoon communication only. Furthermore, compared to other VANET applications, platoons constitute a relatively static network topology where changes only happen in the comparably rare situation of a vehicle leaving or a new one joining the platoon.
Based on this information various applications can be implemented which need access to the knowledge of the current traﬃc situation. The standards for VANETs focus on the interoperability between vehicles from all car manufacturers and hardware from diﬀerent suppliers. Hence, the message transmission on the wireless channel is well studied. In contrast, the A.
