Communications, LLC (Summer Internship)
- Security issues on authentication, authorization,
accounting, and privacy in hybrid networks.
- Categorized security architectures in hybrid networks and
raised security problems.
Permission-Based Sending (PBS) Project
Control plane signaling
architecture for programmable routers
- Proposed a signaling architecture for network traffic
authorization, aiming to prevent denial-of-service (DoS) attacks and
other forms of unauthorized traffic.
- Exploited control plane signaling protocol architecture and
- Implemented this project using netfilter, Click modular
router and NSIS (FreeNSIS).

Seven Degrees (7DS) Project
Distributed wireless networks
of Multicast Service Discovery
- Measured and analyzed multicast service discovery traffic
in a campus wireless network.
different service discovery delay models in terms of packet overhead
and service discovery delay under different network sizes and
Accerelating Service Discovery
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
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
using LEAF (Linux Embedded Application Firewall), an embedded Linux
distribution, on a WRAP (Wireless
Router Application Platform).
