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.

A road surface includes lane marking that store digital information. Images of the road surface and lane markings are acquired by a camera. The digital information is decoded from the images, analyzed so that a feedback signal can be generated according to the decoded digital information.

Method and system for coding digital information in lane markings using an optical sensor

A movable portion of an array of antenna elements receives RF signals. A movable ultra-wideband (UWB) transmitter is connected to each antenna element, via a RF to UWB converter. A fixed portion of the antenna array is separated from the movable portion by an air gap. The fixed portion includes one fixed UWB receiver for each movable UWB transmitter. An application system is connected to the fixed UWB receivers. The UWB signals from the movable transmitter are sent across the air gap to the fixed UWB receivers to be processed by the application system as the movable portion rotates.
