Method and Protocol for Congestion Control in a Vehicular Network
First Claim
1. A node, in a vehicle ad-hoc network (VANET), wherein the node is arranged in a vehicle, wherein the node includes a transmitter, a receiver and a processor for performing steps of a protocol stack, comprising:
- a protocol stack, further comprising;
an application layer;
a link layer; and
a congestion control layer arranged between the application layer and the link layer, wherein the congestion layer is configured to transfer short messages between the application layer and the link layer, and wherein the short messages are defined according to a standard for the VANET, and wherein the congestion layer optimizes a network-wide rate allocation for the short messages.

Abstract
In a vehicle ad-hoc network (VANET), a transceiver node is arranged in a vehicle. The node includes a protocol stack, which includes an application layer, a link layer; and a congestion control layer arranged between the application layer and the link layer. The congestion layer transfers short messages between the application layer and the link layer. The short messages are defined according to a standard for the VANET, and the congestion layer optimizes a network-wide rate allocation for the short messages.
