CUBIC: a new TCP-friendly high-speed TCP variant
The CUBIC protocol modifies the linear window growth function of existing TCP standards to be a cubic function in order to improve the scalability of TCP over fast and long distance networks.

- 7 March 2004
This work presents a new congestion control scheme that alleviates RTT unfairness while supporting TCP friendliness and bandwidth scalability, and uses two window size control policies called additive increase and binary search increase.
On the Levy-Walk Nature of Human Mobility

- 13 April 2008
It is shown that many statistical features of human walks follow truncated power-law, showing evidence of scale-freedom and do not conform to the central limit theorem.
DRAND: Distributed Randomized TDMA Scheduling for Wireless Ad Hoc Networks
- I. Rhee, A. Warrier, J. Min, Lisong Xu
- Computer Science, BusinessIEEE Transactions on Mobile Computing
- 22 May 2006
The algorithm is implemented in TinyOS and shown to be effective in adapting to local topology changes without incurring global overhead in the scheduling, and the effect of the time-varying nature of wireless links on the conflict-free property of DRAND-assigned time slots is evaluated.
Mobile Data Offloading: How Much Can WiFi Deliver?
- Kyunghan Lee, I. Rhee, Joohyung Lee, S. Chong, Yung Yi
- Computer ScienceIEEE/ACM Transactions on Networking
- 30 November 2010
A trace-driven simulation using the acquired whole-day traces indicates that WiFi already offloads about 65% of the total mobile data traffic and saves 55% of battery power without using any delayed transmission.
SLAW: A New Mobility Model for Human Walks
- Kyunghan Lee, Seongik Hong, S. Kim, I. Rhee, S. Chong
- Computer ScienceIEEE INFOCOM
- 19 April 2009
The performance study using using SLAW generated traces indicates that SLAW is effective in representing social contexts present among people sharing common interests or those in a single community such as university campus, companies and theme parks.
SLAW: Self-Similar Least-Action Human Walk
- Kyunghan Lee, Seongik Hong, S. Kim, I. Rhee, S. Chong
- Computer ScienceIEEE/ACM Transactions on Networking
- 1 April 2012
The main contribution of this paper is to present a mobility model called Self-similar Least-Action Walk (SLAW) that can produce synthetic mobility traces containing all the five statistical features in various mobility settings including user-created virtual ones for which no empirical information is available.
TEAR: TCP emulation at receivers – flow control for multimedia streaming
- I. Rhee, Volkan Ozdemir, Yung Yi
- Business
- 2000
The preliminary tests indicate that TEAR shows superior fairness to TCP with significantly lower rate fluctuations than TCP, and the future extension of TEAR for multicast environments is discussed, which is supported in part by NSF CAREER ANI-9875651.
