摘要
针对现有P2P网络搜索效率低、搜索算法开销大等问题,提出采用蚁群搜索算法(ACO)构建P2P层次域网络模型。该模型在域间资源查询时,通过节点信誉度选择查询路径,有效将搜索蚂蚁导向到可能存在查询资源的高信誉度节点域中。实验证明,该方法有效提高了资源搜索命中率,减少了网络中冗余信息包的传送,有一定的实用性及可扩展性。
Aiming at the problems of exiting P2P network,such as low search efficiency,huge message of packets,this paper proposes a layered P2P network model 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 results show that the method can effectively improve the success of resource hit ratio and reduce the message packets,and it has certain practicality and expansibility.
