Abstract：Bufferbloat occurs when excessive packets that exceed the network capacity are blocked in the buffer, which increases the network transmission latency. Cellular networks generally use a large buffer for network reliability, which further aggravates this problem. This paper gives a receive window adjustment scheme based on radio channel state information to mitigate bufferbloat in cellular networks. The scheme retrieves the available bandwidth at the receiver side from the radio channel state information. The effects of channel noise and the ACK self-clocking mechanism in the transmission control protocol are modeled by a Kalman filter to predict the available bandwidth. Then the send window size is adjusted according to the calculated receive window. The scheme performance was evaluated on a network simulation platform with the results indicating that this scheme significantly reduces the queue backlog and the latency while still maintaining the original high throughput than previous mechanisms
