Abstract :
In this paper, we propose an adaptive video transmission scheme to achieve unequal error protection in multichannel ad hoc networks. In our scheme, video data is divided into high priority (HP) and low priority (LP) portions, and mobile nodes have two channels for video transmission. A channel quality metric, busy time ratio (BTR), is employed to characterize the channel quality. The channel with better BTR metric is used for HP data, and the other for LP. Further, adaptive load control and delay-constrained queue management schemes are proposed to improve performance. Simulation results demonstrate the performance of video streaming is greatly enhanced in multichannel multi-hop ad hoc networks.
