Research Projects

  • Wavelength Division Multiplexed Fiber-Optic Network Architecture Modeling, Design, Optimization and Demonstration (dissertation research, with US Navy)
    • Developed a discrete-event-based simulation framework DRAGON that models communication behaviors of a broad register of optical components (in Artifex/C++)
    • Proposed a torus-based 4-way fault-tolerant all-optical architecture for mission-critical communication and guided a team of 4 undergraduates to build up a testbed to verify the fault tolerance design
    • Designed a routing and wavelength assignment scheme under the wavelength-continuity constraint which performs very close to an ideal RWA scheme without the wavelength-continuity constraint
    • Proposed a circulant-graph-based fault-tolerant architecture that supports an arbitrary number of nodes, and developed a corresponding fault-tolerant routing algorithm that provides a flexible number of node-disjoint routes
    • Studied a NP-hard topological optimization problem for spare-sharing-based fault-tolerant all-optical WDM networks and proposed a two-phase heuristic algorithm that outperforms traditional methods which decouple the RWA problem into the routing part and the wavelength assignment part
    • Formally proposed an ordered path enumeration algorithm and developed a candidate routing scheme to facilitate a better-performed integer linear program (ILP) solution than traditional k-shortest disjoint routing based solution
  • Tactical Bandwidth Booster for Seamless Communication in Hybrid Networks (with US Army)
    • Implemented a testbed networking a group of computers emulating heterogeneous network environment via CentOS/Netem/Click/Arsterisk software modules
    • Theoretically modeled and analyzed queuing-induced delay jitter distribution for FIFO and Diffserv queuing
    • Developed, implemented and evaluated an adaptive delay jitter smoothing algorithm
  • Energy-efficient internet: a power-proxy-based smart network interface card (NIC) approach (with Cisco)
    • Investigated feasibility of proxying an instant messaging (IM) protocol on a smart NIC and proposed a corresponding power-proxy model
    • Developed a stochastic-programming-based inactivity time-out setup algorithm to maximize energy saving with smart NIC technology
  • Reservation-based WiMAX network throughput optimization via transmission range control
    • Derived a closer bound for the supportable flow rates in a queue-length-stable WiMAX network based on the two-hop interference model
