摘要： 基于组合层次移动管理协议CHMMP(CombinedHierarchicalMobilityManagementProtocol),设计并仿真实现了一种移动无线Internet中的组播机制·由于在CHMMP下移动,主机在同一外地域内切换时毋需向家乡代理注册,因此所提出的组播机制与IETF的双向隧道和远程加入相比,不仅降低了因切换而致的组播树维护开销,而且显著减小了切换注册延迟·仿真结果表明,该组播机制可以有效地支持移动无线Internet中的组播应用·

Abstract: Based on CHMMP (Combined Hierarchical Mobility Management Protocol), a multicast mechanism was developed for application in mobile wireless Internet. According to CHMMP, the MH (Mobile Host) doesn't need registration with its home agent when it hands over within the same foreign area. Compared with the bi-directional tunnel and remote subscription in accordance to IETF mobile IP, the proposed mechanism can reduce not only the multicast tree maintenance overhead due to handover of multicast, but also the time delay handover registration. Simulation results showed that it could support efficiently group applications in mobile wireless Internet.
