基于效用和细菌群趋药性的柔性QoS单播路由机制

In this paper, based on the knowledge of fuzzy mathematics, microeconomics and swarm intelligence, a flexible QoS unicast routing scheme is proposed with QoS(Quality of Service) satisfaction degree and utility introduced. By BCC(Bacterial Colony Chemotaxis) algorithm, it searches for a QoS unicast path with the maximum of the network provider utility and the user utility achieved or approached at the same time balanced as much as possible. It is implemented by simulation and performance evaluation is done. Simulation results have shown that it is feasible and effective.
