Milestones

Computing and Communications

- March 2004

- Design and analysis of algorithms for the study of distributed computations.
- New efficient methodologies for global computations in a communication network (routing, broadcasting, multicasting).

- June 2004

- Design of new distributed algorithms that determine the geographic location of non-GPS equipped nodes using the geographic location of GPS-equipped neighboring nodes. The algorithms will be simulated (e.g., under NS-2).

- March 2005

- Topologies with improved fault tolerance characteristics.
- Study of the impact of paradigm shifts in modern distributed computing and their relationship to current problems in network computing.

High Speed Data over Wireless Systems

- MPEG 4 video multicasting over MPLS networks.
- Complete analysis of scheduling algorithms for Optical RPR networks.
- Asymptotic behavior of optical networks with large number of wavelengths. Optimal Allocation of Wavelengths in such networks. Simulations and analytical methods.

Self-Scheduling in High Speed Networks

- February 2004

- Construction of hierarchical fuzzy logic controllers for dynamic bandwidth allocation. It is intended that higher level controllers will provide 'smart' inputs to the lower level controllers. For example, higher level controllers that monitors the network continuously could provide new fuzzy rule bases (to accommodate a drastic change in traffic volume) to lower level bandwidth scheduler to avoid 'disasters' there by helping the network to cope up with the problem before they happen.  At present the fuzzy logic controllers used for bandwidth scheduling uses static fuzzy rule base for adjusting the bandwidth among various traffic sources. The proposed hierarchical controllers are well suited for the vision of self-x concept.

- June 2004

- A bandwidth allocation scheme at the cell level or slot level using fuzzy logic controllers and test the feasibility of administering slot level control. A fuzzy logic controller for bandwidth scheduling based on specified Quality of Service.

- November 2004

- A self-learning controller (Meta Module) that uses inputs from the traffic predictor, the traffic scheduler and the data base which contains real time system statistics to adaptively design the structure of the fuzzy CAC so that the system can adapt to drastic changes in traffic and network conditions.

- March 2005

- An algorithm for dynamic bandwidth allocation using fuzzy logic control expressed in terms of solving coupled non-linear differential equations. Obtaining exact or approximate solutions to these non-linear equations will provide new insights into fuzzy logic control.
