【摘要】 在物联网环境下,需要对链路节点之间传输的实时任务进行优化调度,以提高物联网中传感节点的进程管理和内存管理效率。传统方法采用优先级列表控制的物联网环境下的实时任务传输调度方法,在资源分配过程中动态负载平衡性受节点的空间分布的影响较大,任务分配的准确性不高。因此,提出一种基于高效时分多址时隙分配的物联网环境下实时任务传输的分簇调度算法。设计物联网的实时任务调度模型,提取分簇任务信息流的时隙分配尺度特征作为传输指向性函数,设计高效时分多址协议,改进物联网环境下的实时任务协同分簇调度算法,通过高效的时分多址时隙分配,提高了实时任务传输分簇调度的均衡性和准确性。仿真结果表明,采用该方法进行物联网环境下实时任务传输的分簇调度时性能优越可靠。更多还原

【Abstract】 In the environment of Internet of things,it is necessary to optimize the transmission scheduling of the link nodes in order to improve the efficiency of process management and memory management of sensor nodes in the Internet of things.Traditional method adopts the priority list control of the Internet of things in the environment of real-time task scheduling method,so dynamic load balance is affected by the spatial distribution of nodes and the accuracy of task allocation is not high in the process of resource allocation.A clustering scheduling algorithm based on efficient time division multiple access time slot allocation for real-time task scheduling in Internet of things was proposed.The real-time task scheduling model is designed to extract the time slot allocation scale features of the cluster task information flow as the transfer direction function.Efficient time division multiple access protocol is designed and real-time task coordinated cluster scheduling in the Internet of things is improved,improving the balance and accuracy of real-time task scheduling.Simulation results show that when the proposed method is used to transfer the real-time tasks in the Internet of things the performance is superior and reliable.更多还原
