Ant Colony Algorithm Design and Implementation for Link Selection Model Between Nodes in P2P Network

We put forward a virtual link selection model of service quality assurance,and consider the quality of service metrics in this model includes viability,routing cost and so on.Through the analysis of these network parameters,we establish the virtual link selection model of P2P network and give the ant colony algorithm based on simulated annealing.At last,we analysis the feasibility and effectiveness of the algorithm through the experiment.
