Mobile Agent is the component for customized function transferring, activenode provides software application layer, and Agent server processes mobile Agent specific customization. For devel-opment and deployment of specific application protocol, this paper also proposes an abstract protocol framework and aprotocol loading mechanism to enhance network performance.展开更多
Ad Hoc网络是一种没有有线基础设施支持的移动网络,网络中的节点均由移动主机构成。一些无线网关接入协议如移动IP协议、AODV+协议、NOAH协议、DSDV协议都可以通过无线节点接入有线节点,但是各自接入的方式不尽相同。对这几种接入协议...Ad Hoc网络是一种没有有线基础设施支持的移动网络,网络中的节点均由移动主机构成。一些无线网关接入协议如移动IP协议、AODV+协议、NOAH协议、DSDV协议都可以通过无线节点接入有线节点,但是各自接入的方式不尽相同。对这几种接入协议进行比较分析。实验结果表明,MobileIP虽然传输抖动,速率比较低,但不会出现严重丢包,相对比较稳定。AODV+速率比较高,但在网关切换的时候,丢包严重。NOAH,DSDV协议如果不进行分析,设置静态路由,链路断开后,无法自动接入新的网关。展开更多

But its security still needs furtherresearch. After an introduction to mobile IP, IPSec and the threat to mobile IP security,an IPSec-based mobile IP se-curity architecture is presented in the article. This architecture combines IPSec and some other secure measures withmobile IP so as to give mobile IP stronger security. In the article this architecture is discussed in detail and a methodis proposed to traverse firewall using IKE.展开更多
