Fuzzy immune controller synthesis for ABR traffic control in high-speed networks

Dimirovski, Georgi M. (Dogus Author)An end-to-end congestion control design synthesis algorithm for the available-bit-rate traffic in high speed asynchronous-transfer-mode networks is studied via applying the synergy of fuzzy-based intelligence and immune control laws. A fuzzy immune controller is designed to overcome the adverse effects in the network caused by unavoidable uncertainties such as number of users, available bit-rate bandwidth, and propagated transmission delays. Also an algorithm is proposed that can guarantee the minimum cell rate in order to ensure the fair and full utilization of the bandwidth. Simulation investigation has been carried out and the results show the proposed control synthesis is robust and the system performs effectively in adaptive mode. Hence the network's quality-of-service in is guaranteed too
