摘要
P2P对于分布式文件共享具有很好的前景,但当前的P2P系统仍然缺乏有效的信息搜索机制。提出一种基于社会关系的P2P搜索技术,通过挖掘每个节点的兴趣,将包含相似资源的节点组成网络,表现出与社会关系相近的特性,可以有效的提高搜索效率。给出了算法实施的具体步骤,并将仿真结果与其它算法进行比较,表明了该算法的效率优于其它算法,为信息搜索提供了全新的解决之道。
P2P has very good prospects for distributed file sharing, but the current P2P system is still a lack of effective mechanisms of information search. A P2P searching technology based on social relations is advanced. In this model, networks are structured with nodes that include similar resources by digging through each node of interest, this show similar characteristics of social relations, and this effectively promotes searching efficiency. Detailed operation steps are given out and the result of simulation, which is compared to other well-know algorithms, indicated that this algorithm is better than several other algorithms. Finally, this method provided the brand-new solution for information search.
