Shinik Park has received the third prize (Bronze Prize) in Communication/Networks with ExLL:An Extremely Low Latency Congestion Control for Cellular Networks at the 24th Samsung HumanTech Paper Award. In this work, he proposes a receiver-based congestion control for cellular network which adaptively tracks channel fluctuation. Also, ExLL properly adjusts CWND without increasing RTT excessively or losing throughput even in a mobility scenario. ExLL records around 30% RTT gap while TCP Cubic and BBR shows 419% and 143% gaps in real LTE network experiment.
Wooseung Nam has received the second prize (Silver Prize) in the field of Communication/Networks with the research named, "New compression technique with previous synchronized data for Data synchronization", at the 23rd Samsung HumanTech Paper Award. In his work, he proposes a novel network data encoding technique which dynamically eliminates redundancy block of inter-files by exploiting previously synchronized (i.e., transmitted) data. He demonstrated that the novel compression technique largely outperforms available advanced compression techniques. The compression technique was assessed by the reviewers as an alternative of Brotli which is the default network data compression technique for Google Chrome browser.
Euijin Jeong and Jaemin Jo has received the third prize (Bronze Prize) in Communication/Networks with CAS: A Highly Energy-Efficient Context-Aware Scheduler on Background Applications in Mobile Systems at the 22nd Samsung HumanTech Paper Award. In this work, they develop a context-aware application scheduling framework, CAS that adaptively and uniquely unloads and preloads background applications in a timely manner. Also, their trace-driven simulations in comparison with the Android default resource scheduler (i.e., low memory killer) and Android 6.0 with App optimization reveal that CAS-LO increases the battery lifetime by 45% and 28%, respectively, while achieving similar start-up latency.
We have meeting for new semester
At one winter day, we gathered to leave a picture of us.
