Rate adaptation is an essential component in today’s wireless standards, which help approach the channel capacity and maximize the throughput. However, how to estimate the optimal data rate in a fluctuated channel remains of great concern. Previous wisdoms leverage PHY layer information for rate estimation, including confidence information like SoftPHY hints, and channel state information (CSI) measurements...
Rate adaptation is an essential component in today's wireless standards, for its ability to adaptively approach the channel capacity, and maximize the system throughput. The difficulty in rate adaptation stems from estimating the optimal data rate in a fluctuated channel. Previous wisdoms leverage PHY layer information for rate estimation, such as Soft PHY hints or Channel State Information. These...
How to improve the scalability and QoS of peer-to-peer on-demand streaming system based on unstructured overlay is still a problem. Researchers have proposed some memory based buffering schemes to archive the targets. Considering the limited space of memory on one peer, a new caching strategy, which can integrate memory-caching strategy with disk-caching strategy, is proposed to make full use of peers...
