Claim Text:
1. A communication congestion control device, comprising: an external sensor integration processor configured to receive a signal comprising at least one of a sensing signal of a vehicle and a GPS signal and generating driving information of the vehicle based on the signal; a wireless resource management processor configured to received statistic information of a communication condition with a surrounding vehicle and driving information of the surrounding vehicle from a communication processor of the vehicle; a time frame design processor configured to set a time frame based on the communication condition and to set a period of the time frame based on a average driving speed of the vehicle; and a network congestion control processor configured to receive the driving information of the vehicle and the driving information of the surrounding vehicle, to determine a setting change time within the time frame based on the statistic information, to generate transmission data based on the time frame, and to set data transmission rate based on a length of a time slot in the time frame, wherein the statistic information comprises an error rate, and wherein the network congestion control processor decreases a level of transmission power when a data transmission rate is over a maximum data transmission rate available during inter-vehicle communication.
