讨论了基于虚拟骨干网的Ad hoc网络中叶子节点的越区切换机制,在约定的基础上,分别分析了地址改变、路由改变、通信保持,以及由此引起的网络安全问题,并得出了解决这些问题的方案,最后给出了结论.
A leaf node in virtual backbone network may switch to another subnet, and it will change its IP address in accordance with corresponding subnet address. This paper analyzes the issues of handoff, including address alternation, routing, communication maintenance and network security. After this, it raises solutions and gives a conclusion at the last section.
