An adaptive control scheme for real-time MPEG4 video over ad-hoc networks

This paper presents a performance enhancement method for real-time MPEG4 video transmission over mobile multihop ad-hoc networks by employing an adaptive sender rate control scheme. By this control scheme, the sender estimates the available channel bandwidth between the sender and receiver, and adjusts its' output rate of MPEG4 encoder using R-D framework and frame-skip control mechanism to fit the estimated time-varying channel bandwidth. Experiment results show that video quality can be improved by employing this adaptive control scheme.
