Modulation Level Allocation for MGS Streaming Over a Multihop Wireless Channel

This paper introduces a method for efficiently transmitting medium grain scalable video packets over a transmission path consisting of multiple wireless links. Medium grain scalability provides bit rate adaptation according to the available bit rate by dropping a number of video packets in the compressed bit stream. In other words, rate-distortion control can be achieved by means of packet transmission control. The available bit rate and the spectral efficiency are determined by the bandwidth and the modulation level, respectively.
