感知数据的动态传输调度机制与算法研究

In recent years, wireless sensor networks are developing rapidly, and the sensory data transmission scheduling techniques for various kinds of data operations in sensor networks have been widely studied, which provide foundations for fast, collision-free data transmission. With the advent of the era of big data, the scale of sensory data is increasing at a high speed, making transmission scheduling techniques for sensory data more important. However, the existing transmission scheduling techniques are unable to adjust to the dynamic characteristics of wireless sensor networks, thus hard to be applied to various data transmission tasks in wireless sensor networks. The efficient, dynamic maintenance of transmission schedule becomes a challenging problem in wireless sensor networks. To solve this problem, this project aims to conduct a thorough study on the key techniques and theories of dynamic transmission scheduling for sensory data. On the premise of satisfying the application requirements, this project will design a suite of dynamic, adaptive mechanisms and algorithms for sensory data transmission scheduling, which includes task-oriented dynamic transmission scheduling, dynamic scheduling scheme in uncertain sensor networks, dynamic scheduling algorithms for full-duplex wireless sensor networks. On the basis of the research results above, this project will develop a system prototype for dynamic transmission scheduling of sensory data to verify the correctness and efficiency of the proposed techniques.

近年来，无线传感器网络发展迅速，针对传感网上各类数据操作的感知数据传输调度技术被广泛研究，为快速、无冲突地完成数据传输提供了基础。随着大数据时代的到来，感知数据的规模飞速增长，感知数据传输调度技术愈发重要。然而，现有的传输调度技术无法适应无线传感器网络的各种动态性特征，难以高效地应用于无线传感器网络的各种数据传输任务中。如何有效地对感知数据传输的调度计划进行动态维护是传感器网络面临的一个新的挑战性问题。为此，本课题拟对感知数据动态传输调度机制的关键技术和理论进行深入研究，在符合应用需求的前提下，设计出一套动态、自适应的感知数据传输调度机制及算法，包括面向任务的动态传输调度机制、不确定传感器网络上动态传输调度机制、全双工通信模式的传感器网络上感知数据动态传输调度算法等。基于上述阶段性研究成果，研制相应的感知数据动态传输调度系统原型，验证课题所提出方法的正确性和有效性。
