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.
