摘　　要：将P2P应用于电子商务,面临的首要挑战就是如何表达和存储电子商务数据,以及如何高效地搜索到所需数据[1]。针对设计的一个电子商务平台DEP模型,通过引入移动代理和缓存优化机制提高了DEP中的搜索效率。此外还对几种不同的搜索方案进行了对比分析与实验,结果表明DEP本身具有很好的可扩展性,与传统模型相比可以很大程度地降低数据检索时的查询路由次数及系统的通讯量,优化后的搜索算法也取得了很好的优化效果。The main challenge is how to express and store the data when P2P is used in ecommerce. And how to search the required data in P2P ecommerce systems is another challenge. By introducing the mobile agent and caching optimization mechanism into the DEP platform designed by us, the performance of search in DEP is improved. Several search strategy is proposed and their efficiency is analyzed by experiments. The results of the experiments show that the DEP model is high scalable, while the hops in routing and the traffic in system have reduced effectively in data searching compared with traditional model. And the optimized routing algorithm obtain good results.
