A P2P resource search model based on Ant Colony Optimization

Aiming at the problems of exiting P2P network, such as low search efficiency, huge message of packets, this paper propose a P2P resource search mechanism based on Ant Colony Optimization (ACO) algorithm. It directs the searching ants to the domains with higher reputation degree in the inter-domain resource query. The simulation shows that the method is effective improving the success of resource hit ratio and reduce the message of packets, and it has certain practicality and expansibility.
