基于QOS的Mesh网络调度算法

Network scheduling algorithm of Mesh network based QOS

为了实现具有QOS约束的Mesh网络任务调度,提出了一种满足QOS需求的Mesh网络调度方法。首先描述了Mesh网络的QOS约束并给出了数据包的调度方法。然后,在业务调度上提出了2层的调度方法,即根据业务优先级对队列进行调度,然后对节点根据等待时间和任务执行时间设定优先级,从而实现任务调度。仿真实验表明:文中方法能有效地实现Mesh网络任务调度,与其它方法相比,具有较小的网络延迟和较大的优越性。

In order to achieve task scheduling of Mesh network with QOS constraint, a Mesh network scheduling method based on QOS is proposed. Firstly, the scheduling method of Mesh network with QOS constraint is specified. Then, the two-layer scheduling method of business scheduling is proposed, namely, the queue is scheduled according to the priority and the node is scheduled according to the awaiting time and task executing time.The simulation experiment shows: this method can effectively achieve the task scheduling of Mesh network, and compared with the other methods, it has the shorter network time delay and bigger priority.
