随着Intranet迅速发展,私有网络中包含了大量的资源,如何将P2P网络延伸到私有网络中,并对其中的资源进行整合具有重要的研究价值。在分析现有P2P网络资源搜索方法的基础上,提出了一种基于查询代理和广义蚁群算法的资源搜索模型。即在私有网络内部使用查询代理完成资源的查找,在公有网络中使用广义蚁群算法进行资源搜索,并对广义蚁群优化算法进行改进,将节点可信度融入到算法优化条件中。实验表明:该算法能够提高搜索效率和命中率,能够有效地孤立网络中的虚假节点,对提高网络的服务质量具有重要意义。
With the rapid development of Intranet, private network contains a lot of resources. How to extend P2P network into private network and integrate its resources is of great research value. Based on the analysis of existing P2P network resource search methods, a resource search model based on query agent and generalized ant colony algorithm is proposed. In the private network, the query agent is used to search for resources, and the generalized ant colony algorithm is used to search the resources in the public network. The improved ant colony optimization algorithm is improved, and the node credibility is integrated into the algorithm optimization conditions. Experiments show that this algorithm can improve the search efficiency and hit rate, and can effectively isolate the false nodes in the network, which is of great significance to improve the service quality of the network.
