工业物联网密集场景中的演进型时隙分配机制
|
摘要
随着工业无线传感器设备数量的增加,传统IEEE 802. 15. 4 CSMA/CA协议已不能满足工业无线传感器网络密集场景。为此,提出一种演进型时隙分配机制,为密集场景下的工业无线传感器网络提供合理的时隙分配策略。基于当前最大时隙数构建可分配的时隙集合,根据退避状态指数和随机退避数计算位置指数,从而得到时隙分配方程,并依据该方程分配时隙数。通过不断演进CSMA/CA协议,建立状态转移模型。仿真实验结果表明,该机制可提高密集场景中时隙分配的公平性和传输命中率,降低数据发送延迟。
With the increase of industrial wireless sensor devices numbers,the traditional IEEE 802. 15. 4 CSMA/CA protocol cannot effectively meet the industrial Wireless Sensor Network(WSN) dense scenario. Therefore,this paper proposes an evolved time slot allocation mechanism which can provide an effectively time slot allocation strategy for this scenario. A set of allocable time slots is constructed according to the current maximum number of time slots,the position index is calculated based on the backoff state index and the random backoff counter the time slot allocation equation is obtained. The state transition model is established by evolving the CSMA/CA protocol. Simulation expenimented results show that the mechanism can improve the fairness of the time slot allocation and the transmission hit rate in dense scenes and reduce the data transmission delay.
