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.
