We present a receiver-based rate control scheme in an infrastructure network. A mobile device to receive video stream over wireless plays an important role to decide its rate. As an inter-packet delay (IPD) at the sender decreases, the sending rate increases so that the IPD can be adjusted to control the rate, depending on the receiver buffer occupancy. At every round-trip time, such adjustments will be performed in order to achieve a responsive behavior to sudden changes in availability of a receiver buffer. In addition, the proposed method utilizes the discrete derivative of the buffer occupancy to reduce the occurrence of the buffer becoming full.
