针对MANET中QoS需求与隐藏终端等问题,提出了一种基于移动预测的单向QoS路由协议,该协议充分利用网络中存在的单向链路,采用移动预测机制,通过选取满足QoS条件的最稳路径的方式为数据流选择最佳路由,分析和实验结果表明,这种协议具有数据包传送成功概率高和控制开销低等优点,能有效支持单向MANET中具有QoS需求的多媒体信息传输。
A unidirectional QoS routing protocol based on mobility prediction is proposed on the ground with hidden terminal and QoS requirements, and so on. In order to gain good network performance ,this protocol takes full advantage of unidirectional links and selects the steadiest flow routes based on mobility prediction and QoS requirements. Analysis and simulation show that the protocol is characterized with its high probability of successful delivery and low control overhead,and it can supports transmitting multimedia with QoS requirements in unidirectional MANET.
