摘　　要：移动IP借助定期广播的代理通告完成移动检测。与移动IP原本应用的无线局域网环境不同,在移动AdHoc网络中频繁的广播会造成广播风暴。现有的集成移动IP与移动AdHoc网络的方案中提出了多种性能优化的方法,但都没有从根本上解决此问题。论文提出了一种基于局部存储信息的移动检测算法。该算法借助路由协议的Hello信令在邻居节点间传递移动管理信息,帮助移动主机实现移动检测,从而避免移动代理周期性地广播代理通告给网络造成的性能开销。仿真结果表明,基于Hello信令的移动检测算法可以改善网络中数据通讯的传输性能。实际的测试床实现检验了算法功能的完备性。Mobile IP uses Agent Advertisement which broadcasts periodically to implement mobility management.To be different with WLAN which Mobile IP originally designed for,frequently broadcast in MANET will cause the broadcast storm problem.Many solutions have been presented in literatures to improve the performance,but they all don＇t resolve this problem thoroughly.This paper proposes a new Mobility Detect algorithm which leverages neighborhood information to avoid broadcast message transmitted periodically.The algorithms of Agent Solicitation and Agent Advertisement in mobile nodes are redesigned to adapt to the nature of MANET.The simulation result shows that network transmission speed is improved by adopting the new algorithm.The functionailty of Mobility Management is verified in test-bed of the real world.
