Objective
Seeking a challenging career in research, design and development of Communication Networks.

Research summary
Current research involves algorithms for inferring core QoS capabilities of multi-class networks. Using measurements obtained from the network edge, inter-class resource sharing theory and standard estimation and dection algorithms, our goal is to design a unified framework for inferring core QoS network features. This framework can be used in various areas, such as: network control and management, call admission control, SLA validation and bandwidth planning. Future research involves estimation of the unknown cross-traffic and an extended framework application in web servers.

Projects

Research

• INternet Control and Inference Tools at the Edge (INCITE), Rice University (present)
  The goal of the project is characterizing network service based solely on edge-based measurement at hosts and/or edge routers. The specific goal is to infer core QoS network capabilities using passive packet monitoring at the edge network routers.
• Cross-traffic Estimation Project, Ericsson's Traffic Analysis and Network Performance Lab, (Summ. '01)
  In this project we developed an active probing scheme that is used for the estimation of the available bandwidth on an end-to-end network path. The goal was to accurately characterize cross-traffic, and to detect and sort cross-traffic on different bottlenecks using exclusively end-to-end measurements. The scheme has been implemented in Linux and tested in the real-network environment.
• Interactive Multimedia Communications, MPI, (June '99)
  The goal of the project was to performe simulation based performance analysis of a multipoint data communication service and protocol in a multimedia environment. A global flow control based on ITU-T.122 and T.125 recommendations was examined. Analysis was made for PSTN/LBRM network. Appropriate C++ simulation software has been developed in that purpose.

Development

• PP2M-1p HDSL modem software development and implementation, MPI, (Oct. '98)
  Wrote C drivers and implemented software for the pilot version of HDSL single-pair modem desiged in Mihajlo Pupin Institute Telecommunications Lab. Modem was based on Metalink xDSL chip set and Intel microprocessor.
  

Course

• Vertical Handoff in Multi-Tier Wireless Networks, Rice University, (Dec. '99)
  Proposed and evaluated algorithm for vertical handoff in multi-tier wireless network environment. The objective of the algorithm was to optimize handoff policy considering network utilisation, power consumption and different mobility patterns. Also, particular attention was payed to the problem of handoff synchronization.
• Dynamic QoS Routing in Multi-Class Networks, Rice University, (Dec '99)
  Performed a simulation based performance analysis of a QoS routing protocol which considers the utilization state not just on link bases as usually done, but also considers per-class load states.
• LPC Vocoder and Spectral Analysis, Rice University (May '00)
  Implemented and compared several frequency and time based algorithms for the pitch period estimation. Also, a two-state LPC vocoder synthesizer was made. All of the above was implemented in MATLAB.
