MODELING OF A FUZZY TRAFFIC CONTROLLER FOR ATM NETWORKS USING VHDL
Synopsis:
This project deals with the design of a traffic controller for traffic management in ATM(Asynchronous Transfer Mode)Networks using VHDL. This controller manages the congestion control and call admission control simultaneously. When a new call set up is requested, this system calculates the bandwidth requirement, and depending on the available bandwidth and system performance, it takes a decision on accepting or rejecting the call. This was a fuzzy based implementation, which not only utilizes the mathematical formulation of classical control but also mimics the expert knowledge of traffic control. The system utilization and overall performance is also improved by the use of the fuzzy traffic control. Report
GRADUATE THESIS(Presently working)
RECONFIGURABLE ANTENNA FOR MOBILE COMMUNICATION
Synopsis:
The work concentrates on bringing in the most used frequency bands in mobile communication namely 0.9,1.8 and 2.4GHz under one patch antenna. Different frequency bands is achieved by placing shorts at appropriate position which decreases the electrical length of the antenna thereby increasing the resonant frequency. Designs were successfully simulated in IE3D(Electromagnetic simulator using Method of Moments) and fabricated. The fabricated antenna responded well to first two frequencies with a good match . Presently working on the third frequency(2.4GHz). On completing this, radiation pattern and gain will be measured. If everything goes on well, patent will be filed for this design. Results so far..
