| 摘 要： | 在AVAODV协议的基础上增加带宽估计选项,提出了一种基于带宽估计和链路稳定度的QVAODV路由协议。QVAODV协议在路径寻找的过程中,通过带宽估计和链路稳定度的计算,从众多备选路径中选择出一条满足带宽需求和链路稳定度最好的路径来提供QoS保证。仿真实验结果表明,在相同实验条件下QVAODV协议在数据丢包率、平均端到端分组时延和平均路由开销性能方面与AVAODV协议相比均有提高。

| Abstract: | The proposed routing protocol QVAODV comes from AVAODV protocol and is added bandwidth estimation option and it based on bandwidth estimation and link stable parameter.In the process of path discovery in QVAODV protocol,it selects a path which satisfys bandwidth demand and the highest link stable parameter from many candidate paths to provide QoS guarantee by bandwidth estimation and the calculation of link stable parameter.Simulation results show that QVAODV protocol is better than AVAODV protocol in data loss rate,average peer-to-peer delay and average routing overhead under the same experimental conditions. |
