Congratulations to Shinik Park and Junseon Kim for their paper accepted at ACM CoNEXT 2018!!

[ ABSTRACT ]Since the diagnosis of severe bufferbloat in mobile cellular networks, a number of low-latency congestion control algorithms have been proposed. However, due to the need for continuous bandwidth probing in dynamic cellular channels, existing mechanisms are designed to cyclically overload the network. As a result, it is inevitable that…

Winning 3rd prize at the 24th Samsung HumanTech Paper Award

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…

VehicleSense: A Reliable Sound-based Transportation Mode Recognition System for Smartphones - Presented at IEEE WoWMoM 2017

So far, there have been no previous works with a satisfying performance in terms of a latency, a recognition accuracy and an energy efficiency at the same time. VehicleSense achieves all of these performances simultaneously by utilizing the unique characteristics of a sound of vehicles and implementing accelerometer-based trigger systems.…

QuickTalk: New Communication Method for IoT Devices

IoT devices are in general considered to be straightforward to use. However, we find that there are a number of situations where the usability becomes poor. The situations include but not limited to the followings: 1) when initializing an IoT device, 2) when trying to control an IoT device which…
