基于被动服务发现的Ad hoc接入机制

An Access Mechanism Based on Passive Service Discovery in Ad hoc Network

Ad hoc网络通常是以一个独立的通信网络形式存在的,但在很多情况下,仅仅依靠独立的Ad hoc网络已经无法满足用户的需求,Ad hoc网络只有与其它网络实现互连互通才能真正发挥各个网络的潜能。因此,深入研究Ad hoc网络的接入问题具有重要意义。文中针对上层应用服务的建立过程,在服务定位SLP协议基础上,提出了一种基于被动模式的服务发现机制,并深入阐述了服务的被动发现过程,进而对该介入机制中的相关会话及安全等问题提出管理方案和措施。

Ad hoc network is usually in the form of an independent communications network, however,in many cases, users＂ need can＇t be met by relying on Ad hoc networks only ,just exploit Ad hoc＇s potential when it is intercommunicated with other networks. Therefore,it is of great significance to study deeply the access issue of Ad hoc network. Present a passive mode of service discovery mechanisms on the basis of the SLP position service agreement, and illustrate in-depth the passive discovery process of service,putting forward the manage- ment scheme and measures for such issues as related security ＆ conversations problem of this mechanism.
