Intelligent QoS Unicast Routing Scheme in SON

In this paper, a swarm intelligence based quality of service (QoS) unicast routing scheme is proposed for self-organized network (SON). The inaccurate routing information is described with fuzzy methods whilst the utilities of both the user and the network provider are taken into account by applying gaming. Based on AntNet algorithm, a QoS unicast path is found on which Pareto optimum is approached or achieved under Nash equilibrium of the user utility and the network provider utility.
