Journal ArticleDOI
XORs in the air: practical wireless network coding
TL;DR: The results show that using COPE at the forwarding layer, without modifying routing and higher layers, increases network throughput, and the gains vary from a few percent to several folds depending on the traffic pattern, congestion level, and transport protocol.
Journal ArticleDOI
Tool release: gathering 802.11n traces with channel state information
TL;DR: The measurement setup comprises the customized versions of Intel's close-source firmware and open-source iwlwifi wireless driver, userspace tools to enable these measurements, access point functionality for controlling both ends of the link, and Matlab scripts for data analysis.
Journal ArticleDOI
XORs in the air: practical wireless network coding
TL;DR: The results show that COPE largely increases network throughput, and the gains vary from a few percent to several folds depending on the traffic pattern, congestion level, and transport protocol.
Proceedings ArticleDOI
Predictable 802.11 packet delivery from wireless channel measurements
TL;DR: It is shown that, for the first time, wireless packet delivery can be accurately predicted for commodity 802.11 NICs from only the channel measurements that they provide, and the rate prediction is as good as the best rate adaptation algorithms for 802.
Proceedings ArticleDOI
LightSync: unsynchronized visual communication over screen-camera links
Wenjun Hu,Hao Gu,Qifan Pu +2 more
TL;DR: Across several phones, this system can more than double the average throughput compared to previous approaches, and features in-frame color tracking to decode imperfect frames and a linear erasure code across frames to recover lost frames.
