摘要:

针对子网整体移动的问题,分析了移动IP的不足,借鉴IPv6中的网络移动性,提出在现有IPv4网络中可支持子网整体漫游的MIP-RS协议. 移动子网以STA/AP为网关,通过家乡代理、外地代理和网内选路代理之间的协作,结合隧道技术实现了多跳的移动IP,突破了移动IP技术中从家乡代理与外区代理间隧道出口到移动点只能有“一跳”的限制,使网络中所有节点可通过多跳访问移动子网中的节点,实现移动子网的漫游. 基于自行研发的STA/AP实现了MIP-RS. 实测结果表明,在子网以车速移动时移动子网中的节点和固定网络中的节点能进行高速双向数据通信.

Abstract:

To support a subnet moving in the IPv4 environment, a roaming subnet supported mobile IP protocol (MIP-RS) is proposed by avoiding shortcomings of the mobile IP. In MIP-RS, STA/AP works as a gateway instead of as a MAC device. It is implemented by cooperation between the home agent, the foreign agent, and the intra-domain routing agent. Distance of the node in a mobile subnet from the HA-FA tunnel’s exit can be multi-hops, while it is only one-hop in the mobile IP. A demo system including the special STA/AP was developed to verify MIP-RS. Test results show that MIP-RS can provide high speed data transmission during the subnet moving at the vehicle speed.

Key words: mobile communication, roaming, mobile IP protocol, agent, tunnel
