与连接到硬连线网络的固定主机相比，由于自动配置、全局连通性和分层寻址方案的部署，MANET中的移动裸体可以更频繁地改变其IP地址。当IP地址改变时，单播路由协议和实时通信的性能可能会降低，并且MANET内的隐私可能会受到损害。虽然已经有一些自动配置算法被提出用于为移动节点分配唯一的IP地址，但由于地址改变而导致的开销还没有被仔细研究。在研究地址变化带来的开销的基础上，提出了一种扩展单播路由协议和网络地址转换(NAT)方案的IP地址切换方案。我们的分析和原型实现证明，该方法能够弥补中断的路由结构和正在进行的通信的开销。
When compared with a fixed host that is connected to a hardwired network, a mobile nude in the MANET may change its IP address more frequently due to the deployment of autoconfiguration, global connectivity, and hierarchical addressing schemes. When an IP address changes, the performance of unicast routing protocols and real-time communications may degrade, and privacy may be compromised within the MANET. Although there have been some autoconfiguration algorithms proposed for the assignment of unique IP addresses to mobile nodes, the overhead resulting from address changes has not been carefully examined. Based on studies of the overhead caused by address change, an IP address handoff solution, which extends the unicast routing protocol and network address translation (NAT) scheme, is proposed in the paper. The proposed approach is able to offset the overhead of broken routing fabrics and on-going communications, which is supported by our analysis and a prototype implementation.
