摘要
对ODMRP(on demand multicasting routing protocol)这一广泛应用于移动自组织网络(MANET,mobile ad-hoc networks)的组播协议进行改进,提出了QODMRP协议,以支持QoS(quality of services)组播.该协议着重考虑时延与通信链路带宽QoS约束.在Join Query与JoinReply报文中增加了与QoS相关的域,将转发组成员分成为"非QoS成员"与"QoS成员"两类,分别转发普通数据分组与QoS约束的数据分组.该协议适用于MANET中传输多媒体数据.
The ODMRP （on demand multicasting routing protocol）, a protocol widely used in mobile ad-hoc networks （MANET）, is improved to support QoS （quality of services） multicasting. A protocol referred to as QODMRP is proposed. The QODMRP emphasizes on investigating multicasting under constraints of delay and link bandwidths. Both the format of Join Query and that of Join Reply are modified to embed QoS fields. Additionally, nodes in forwarding group are divided into two classes, i. e, ＂non-QoS member＂ and ＂QoS member＂, which respectively deliver normal packets and QoS constraint packets. The QODMRP is applicable to deliver multimedia packets in MANET.
