摘　　要：鉴于生物体的运作机制已被广泛地用于提高分布式系统的性能,将概念之间的语意相似度引入到基于蚁群搜索算法的对等网络协议,并对资源检索、信息素更新以及节点异动处理等机制进行了研究。在模拟实验中,将上述协议与K路随机游走协议进行了性能比较,结果表明基于蚁群搜索算法的语意对等网络协议不仅能够提高查询效率而且能减轻网络的负载。Because the operating mechanism of living organism have been extensively used to improve the performance of distributed system, the semantic similarity was introduced into the P2P protocol based on ants search algorithm and some researches on the mechanism of retrieving resource, updating pheromone, treating with the changes on the network were done. In the simulation experiments, the performances of new protocol and k-random ways protocol were compared and the results show that semantic P2P protocol based on ants search algorithm can not only increase the efficiency of searching keywords but also decrease the load of P2P network.
