针对目前无线Mesh网络尚未解决多网关接入时最小链路调度时间下限估计的问题,提出一种计算该时间下限的方法,其本质是基于资源分配的Pareto优化计算过程.采用拉格朗日方法进行求解,并通过Lyapunov函数找出基于最优速率的多网关接入的最小链路调度时间.该方法不仅能准确地计算出最小链路调度时间下限,并用于评估网络性能,还能优化无线Mesh网络上行链路调度速率,提高链路的吞吐量.
Aiming at the problem of the minimum link scheduling time lower bound estimation in multi-gateway access when the wireless mesh network is not yet solved, a method to calculate the lower bound of the time is proposed, which is based on the Pareto optimization process of resource allocation.Using Lagrange method And find the minimum link scheduling time of multi-gateway access based on the optimal rate through the Lyapunov function.This method not only can accurately calculate the minimum link scheduling time limit, and is used to evaluate the network performance, but also optimize the wireless Mesh network uplink scheduling rate, improve link throughput.
