Abstract
A congestion control access gateway and a congestion control method for the same are provided. The congestion control access gateway interfaces between a broadband convergence network and a ubiquitous sensor network including sensors and terminals. The congestion control access gateway receives data from the ubiquitous sensor network. When a congestion situation has occurred, the congestion control access gateway detects the congestion situation based on data received in the congestion situation and broadcasts congestion notification and control messages in response to the congestion situation detection. The congestion control access gateway generates a congestion situation detection profile as a result of the congestion situation detection and performs priority queuing of the received data based on the congestion situation detection profile and service classes. The congestion control access gateway determines destination of the queued data using the congestion situation detection profile and routes the data to a corresponding service.
