摘要
为解决目前P2P网格资源查找算法资源查找效率低下的问题,结合网格环境中普遍存在的幂律现象,提出了分层的网格资源查找模型,给出了一种新的资源查找方法.仿真结果表明,该方法利用历史查询信息,减少了无效查询次数,提高了网格资源查找效率.
In order to solve the problem that the efficiency of current resource discovery algorithm in P2P-grid is very low, a model of resource discovery by layers was proposed, combined with the Power-law phenomenon universally existing in the grid world, and a new way of resource discovery was presented. By simulation it shows that the proposed method decreases times of invalid query by using the discovery information over the past, increases the efficiency of grid resource discovery greatly.
