摘　　要：为了改进非结构P2P网络中搜索机制效率低下的问题,提出了一种新的非结构P2P网络资源搜索方法.在Gnutella泛洪搜索的基础上,利用蚁群算法的信息素的思想,指导资源搜索的方向,从而减少了消息信息量,提高了搜索速度.模拟实验表明该模型对搜索请求具有较高的效率和准确性.To improve the searching efficiency of unstructured P2P network, a new method of resource search in unstructured P2P was brought forward. Based on flooding of Gnutella, the resource search of P2P network was instructed by using pheromone of ant colony algorithm, which reduced the quantity of the information and improved the rate of model has a relative high efficiency and accuracy.
