QoS参数的相关性研究对多约束条件下的QoS路由优化具有重要意义.本文结合仿真和理论分析,研究了移动ad hoc网络中三个重要的QoS参数——业务流的带宽、分组平均延迟、延迟抖动——的相关性问题,得到了这些参数问关系的解析表达式来.通过进一步的仿真验证,结果表明所得到的关系与试验结果相吻合.
It is important for multi-constrained QoS muting to study the pertinences of QoS metrics. This paper investigates the pertinence of bandwidth,average packet delay and delay jitter in mobile ad hoc networks by simulation and analysis. The formulations denoting the pertinence of these QoS metrics are obtained, and simulations are performed to validate correctness of these formulations. The simulation shows that the analytical results are consistent with simula- tion results.
