摘要

ODMRP的主要优势之一是它的单播路由能力。ODMRP不仅可以与任何单播路由协议共存，而且可以同时具有组播和单播的功能。因此。ODMRP可以在没有任何底层单播协议的情况下运行。其他特别组播协议，如AMRoute、CAMP、RBM和LAM，必须运行在单播路由协议之上。CAMP、RBM和LAM仅适用于某些底层单播协议。本文提出了一种按需路由协议，该协议利用从移动主机获得的移动信息来预测拓扑变化。该方案在路径失效之前为实时流执行重路由。这是通过我们称之为“多跳切换”的机制完成的。我们的目标是尽量减少由于移动性造成的实时会话中断

A Multicast Routing Protocol for Multi-Hop Wireless Networks: ODMRP

One of the major strengths of ODMRP is its unicast routing capability. Not only can ODMRP coexist with any unicast routing protocol, it can function as both multicast and unicast. Thus. ODMRP can run without any underlying unicast protocol. Other ad hoc multicast protocols such as AMRoute, CAMP, RBM, and LAM must be run on top of a unicast routing protocol. CAMP, RBM and LAM in particular only work with certain underlying unicast protocols. In this paper we propose a on demand routing protocol which uses the mobility information obtained from the mobile hosts to predict topological changes. The scheme performs rerouting for a real time flow before a path becomes invalid. This is done using a mechanism we refer to as "multi-hop handover". Our goal is to minimize disruptions of real time sessions due to mobility
