Web搜索中MA克隆判断的改进算法

Improved Mobile Agent Clone Judgement Algorithm in Web Search Engine

克隆条件的设定是基于Web搜索中MobileAgent(MA)克隆技术的核心关键问题。分析了现有MA克隆条件判断技术应用于搜索引擎的不足,在此基础上,根据QoS的原理,针对Web服务器端的负载和MA搜索代理间的平衡问题,在保证服务器的其他浏览请求优先的情况下,使用统计学方法提出了一种适用于基于MA的搜索引擎的克隆条件判断算法,克服了原有克隆判断参数难以获得的缺点。

In mobile agent-based Web search engine, how to decide clone condition of mobile agent(MA) is the key problem. In this paper, we analysed the disadvantages of existing MA clone judgement algorithms and presented an improved MA clone judgement based on QoS principle. To ensure the priority of server' request,an threshold strategy is used to balance the load between Web server and MA search agent.This improved algorithm overcomes the relative argument's gaining difficulty and is suitable to MA-based Web search engine.
