Title
Dsvm: A Buffer Management Strategy For Video Transmission In Opportunistic Networks
Abstract
In recent years, more and more people have begun to focus on data delivery among mobile users through opportunistic networks, and in most cases, such as emergency, traffic accident and disaster, we need to transmit video data to other users by the means of opportunistic contacts between mobile users. Meanwhile, the buffers of mobile wireless devices are usually limited, then some messages which have different importance on video recovery, will be dropped during transmission. Therefore, it's imperative to design efficient buffer management strategy to improve the video delivery quality. Several policies have been presented, but they are just designed for general data and not suitable for video transmission. In this paper, we comprehensively take the temporal correlation of video data and the diffusivity of messages into account, and propose DSVM, a novel buffer management strategy. Extensive simulations validate its performance, and up to about 3dB Peak Signal-to-Noise Ratio (PSNR) gain can be achieved over the state-of-the-art buffer management policies.
