Search All Patents in Smart Cities: V2X
Self-driving and autonomous vehicles are very popular these days for scientific, technological, social, and economical reasons. In one aspect of this technology, one of the main concerns for an implementation of any V2X technology on a large scale is the issue of congestion control. In large cities and crowded highways during rush hours, each host vehicle can get messages from over 200 other vehicles and several road side units, all working on the same channel and trying to send and receive messages at the same time. With respect to the weather effect on signal, the signal path loss occurs whenever there is moderate (or moderate plus) rain, and because of that, the OBU communications packets are prone to get lost, or communication coverage region gets diminished, depending upon the intensity, speed, angle and temperature of the rainfall/snowfall droplets. We have provided the solutions for these 2 problems, with variations.
