摘要: P2P因良好的可扩展性、低廉的部署开销及能够聚集闲置资源等优点而被广泛应用于文件共享领域。移动自组网(MANET)是一种具有高度动态拓扑结构、节点任意移动的自组织网络,与P2P有很多共同点,近来开始出现了将两者融合的研究。该文提出一种在MANET环境下基于结构化P2P的资源共享模型,将MANET中的节点按其物理位置组成多个域,每个域中有若干节点,域和域中的节点用CAN管理。模拟结果显示该模型可以明显减少路由所需的跳数。

Abstract: While largely developed independently of each other, P2P overlay networks in Internet and Mobile Ad Hoc Networks(MANET) share many key characteristics such as self organization and decentralization. This paper provides an overview of existing service discovery approaches in MANET. In order to overcome their drawbacks, it presents a structured P2P system R-CAN to reduce routing hops in MANET, and the entire system consists of a set of regions where peers are in proximity. Experimental results show that R-CAN can greatly enhance the system performance and effectively reduce the routing hops.

Key words: P2P network, Mobile Ad Hoc Networks(MANET), resource share
