Research Experience
09/2007 ~ Present
PBS (Permission-Based Sending) Project
Columbia University
- Signaling architecture for network traffic authorization.
- Preventing denial-of-service attacks and other forms of unauthorized traffic.
- Exploiting control plane signaling protocol architecture and secure authorization
(permission).
06/2007 ~ 08/2007
Evalution of a DHT-based P2P system
Bell Labs at Alcatel-Lucent (Summer Internship)
- Evaluated the control message overhead needed to maintain the
architectures and stabilization of the architectures under various
churn rates and networking sizes.
- Showed the proper update period of the stabilization process
for maintenance of the P2P architecture and the bandwidth usage through
theoretical analysis.
- Simulated this project using OMNeT++ and OverSim.
01/2006
~ 05/2007
7DS Project
Columbia University
Measurements of Multicast Service Discovery
- Measured and analyzed multicast service discovery traffic in a campus wireless network.
- Analyzed
different service discovery delay models in terms of packet overhead
and service discovery delay under different network sizes and
mobilities.
Accerelating Service Discovery
- Proposed and algorithm to accelerate service discvory in wireless Zero
Configuration Networking (Zeroconf) mobile ad hoc networks.
- Allowed users to discover network topology changes and new services in real-time while minimizing network overhead.
- Implemented and tested this project on
Linux, using C.
P2P Information Exchange
- Worked on data exchanges on wireless mobile ad hoc networks
by
providing an application-level set of protocol services that will
enable exchange of information between peer devices.
- Implemented and tested this project on Linux using
C, and also implemented and tested
it
using LEAF (Linux Embedded Application Firewall), an embedded Linux
distribution, on a WRAP (Wireless
Router Application Platform).
01/2004
~ 12/2005
The Armstrong Project
Columbia University
Funneling-MAC
protocol
- Worked on a localized and sink-oriented MAC
protocol in wireless sensor
networks, focusing on congestion control and aggregation of
information.
- Wrote a C++ code of this protocol and tested it on
NS-2
simulator.
