摘要:

在本文中,我们研究了面向智慧城市、智能工厂和网联汽车等场景的物联网系统。为了在广域范围内以低功耗支持此类系统,无需有线充电基础设施的能量收集技术是实现网络长寿命的重要问题之一。考虑到根据节点和能源的分布,每个设备的位置以及所充入的能量可能并不均衡,最大化所有节点之间最小吞吐量的问题成为一个具有挑战性的 NP-hard 问题。为克服这种复杂性,我们提出了一种基于机器学习的中继拓扑算法,该算法采用一种新颖的反向传播速率评估方法来给出合适的学习方向,并提出一种迭代均衡时隙分配算法,能够利用能量充足的节点作为中继。为验证所提方案,我们在所建立的系统模型上进行了仿真,从而证实所提方案是稳定的,并且优于传统方案。

英文摘要:

In this paper, we examine the internet of things system which is dedicated for smart cities, smart factory, and connected cars, etc. To support such systems in wide area with low power consumption, energy harvesting technology without wired charging infrastructure is one of the important issues for longevity of networks. In consideration of the fact that the position and amount of energy charged for each device might be unbalanced according to the distribution of nodes and energy sources, the problem of maximizing the minimum throughput among all nodes becomes a NP-hard challenging issue. To overcome this complexity, we propose a machine learning based relaying topology algorithm with a novel backward-pass rate assessment method to present proper learning direction and an iterative balancing time slot allocation algorithm which can utilize the node with sufficient energy as the relay. To validate the proposed scheme, we conducted simulations on the system model we established, thus confirm that the proposed scheme is stable and superior to conventional schemes.
