摘　　要：对低移动性、频繁搜索文件的无线Ad-Hoc网络,提出一种新型P2P文件共享系统,介绍一种将文件查找和路由功能统一起来形成跨层的方案。所有共享文件采用全分布哈希表,在无线网络拓扑结构建立的同时存储和保留位置信息以及路由信息,通过节点间的树形逻辑结构解决共享文件的定位查询和下载问题。In this paper, a new type of P2P file-sharing system is proposed for low mobility, frequently searching files wireless Ad-Hoe network,a new cross-layer scheme that unifies document search and routing function together is introduced. All shared files in all Hash table, and the location information and routing information are storaged at the same time while the wireless network topology is set up.The problem of positioning query and download among shared file are solved by the tree logic structure among the nodes.
