控制与转发分离的工业无线网络资源调度技术

Resource scheduling technology based on separation of control and forwarding in IWSNs

工业无线传感器网络(Industrial Wireless Sensor Networks,IWSNs)作为一种新兴网络,是将原有封闭的网络体系解耦为应用平面、控制平面和数据平面.本文研究控制与转发分离的资源调度技术,描述控制平面的控制功能、数据平面的转发过程及IWSNs特有的协议栈跨层调度思想.以时间为维度,区分控制通道和数据通道,实现时隙级的控制与转发分离.实验结果表明:采用控制与转发分离的资源调度模式可以有效提高通信质量.

As emerging networks, industrial sireless sensor networks （IWSNs） disintegrate the o- riginal closed network system into application plane, control plane and data plane. This paper studies resource scheduling technology based on separation of control and forwarding and de- scribes the control function of control plane, the forwarding process of data plane and cros-layer scheduling of IWSNs protocol stack. Based on time dimension, this paper distinguishes control channel and data channel for transmitting control information. The experiment results illustrate that resource scheduling based on separation of control and forwarding could improve the commu- nication quality.
