Network device vendors have recently opened up the processing capabilities on their hardware platform to support third-party applications. In this paper, we explore the requirements and overheads associated with co-locating middlebox functionality on such ...
 
How to Mitigate Signal Dragging during Wardriving
Found in: IEEE Pervasive Computing
By Jinyoung Han, Jeongkeun Lee, Ted
Issue Date:January 2010
pp. 20-27
In wardriving, test devices in moving vehicles measure received signal strengths (RSSs) from nearby base stations (BSs) and record them with location information, which is a key component in localization technologies. In this article, the authors analyze t...

Issue Date:August 2012
pp. 149-160
Spectrum management and device coordination for Dynamic Spectrum Access (DSA) networks have received significant research attention. However, current wireless devices have yet to fully embrace DSA networks due to the difficulties in realizing spectrum-agil...
     
Revamping the IEEE 802.11a PHY simulation models
Found in: Proceedings of the 11th international symposium on Modeling, analysis and simulation of wireless and mobile systems (MSWiM '08)
By Jeongkeun Lee, Jiho Ryu, Sung-Ju Lee, Taekyoung Kwon
Issue Date:October 2008
pp. 286-293
In simulating wireless networks, modeling of the physical layer behavior is an important yet difficult task. Modeling and estimating wireless interference is receiving great research attention, and is crucial in a wireless network performance study. The im...
     
An experimental study on the capture effect in 802.11a networks
Found in: Proceedings of the the second ACM international workshop on Wireless network testbeds, experimental evaluation and characterization (WinTECH '07)
By Daehyung Jo, Jeongkeun Lee, Jiho Ryu, Sung-Ju Lee, Taekyoung Kwon, Wonho Kim, Yanghee Choi
Issue Date:September 2007
pp. 19-26
In wireless networks, a frame collision does not necessarily result in all the simultaneously transmitted frames being lost. Depending on the relative signal power and the arrival timing of the involved frames, one frame can survive the collision and be su...
     
CSpy: finding the best quality channel without probing
Found in: Proceedings of the 19th annual international conference on Mobile computing & networking (MobiCom '13)
By Bozidar Radunovic, Jeongkeun Lee, Kyu-Han Kim, Souvik Sen
Issue Date:September 2013
pp. 267-278
Wireless performance depends directly on the quality of the channel. A wireless transmitter can improve its performance by estimating and transmitting on only the strongest channel, which can be of significantly higher quality than a weak channel (yielding...
     
Application-awareness in SDN
Found in: Proceedings of the ACM SIGCOMM 2013 conference on SIGCOMM (SIGCOMM '13)
By Gowtham Bellala, Guevara Noubir, Jeongkeun Lee, Manfred Arndt, Tao Jin, Zafar Ayyub Qazi
Issue Date:August 2013
pp. 487-488
We present a framework, Atlas, which incorporates application-awareness into Software-Defined Networking (SDN), which is currently capable of L2/3/4-based policy enforcement but agnostic to higher layers. Atlas enables fine-grained, accurate and scalable a...
     
No more middlebox: integrate processing into network
Found in: Proceedings of the ACM SIGCOMM 2010 conference on SIGCOMM (SIGCOMM '10)
By Jean Tourrilhes, Jeongkeun Lee, Puneet Sharma, Sujata Banerjee
Issue Date:August 2010
pp. 112-ff
Traditionally, in-network services like firewall, proxy, cache, and transcoders have been provided by dedicated hardware middleboxes. A recent trend has been to remove the middleboxes by deploying the network services into switch/router-integrated computin...
