MP2P中资源检索方案研究

MP2P技术中以网络资源的搜索最为重要,因此文章研究了当前一段时间出现的性能出色的资源搜索算法,提高文件检索效率和减少无线环境中的网络拥堵等问题,重点分析了几种比较典型的资源搜索算法:集中式和洪泛式,该检索方式帮助节点在邻居间有效地进行资源请求;分布式资源搜索,有效地提高了查询效率;有基于组或者超级节点的,查询时间缩短了,但是投入的代价偏大。文章对这几种资源搜索算法做了总结和详细对比。

Resources Retrieval Scheme Research in MP2P

Searching the resource is most important in MP2P. So this article studies the performance of the current period of time of resource search algorithm, how to improve the efficiency of document retrieval and reduce network congestion problem in wireless environment. This article analyses the four kinds of typical resource search algorithm. They are centralized and flooding, such as 1.4, the retrieval methods using IA mechanism to help requests for resources effectively between nodes in the neighborhood. They may be distributed effectively to improve the query efficiency. Based on group and based on the super node, the query time is shortened, but the price is high. Finally, the several excellent resource search algorithms have made the summary and the detailed comparison.
