Amin Azari, Cicek Cavdar

摘要:

实现大规模节能物联网(IoT)连接是实现网络化社会的重要一步。虽然传统的广域无线系统高度依赖于网络侧协调,但信令中消耗的能量水平以及物联网设备数量的预期增加使得这种集中式方法在未来不可行。在这里,我们通过从过去的通信中学习,通过物联网网络的自我协调来解决这个问题。为此,我们首先研究适用于物联网通信的低复杂度分布式学习方法。然后,我们提出了一个学习的解决方案,以适应设备的通信参数的环境,以最大限度地提高能源效率和数据传输的可靠性。此外,利用随机几何工具,我们评估了建议的分布式学习解决方案对集中式协调的性能。最后,我们分析了能源效率之间的相互作用,通信的可靠性,对噪声和干扰的数据信道,并对对抗性干扰的数据和反馈信道的可靠性。仿真结果表明,与最先进的方法相比,使用所提出的学习方法可以显着提高物联网通信的能效和可靠性。这些使用轻量级学习实现的有希望的结果使我们的解决方案在许多低成本低功耗物联网应用中非常有利。

英文摘要:

Enabling large-scale energy-efficient Internet-of-things (IoT) connectivity is an essential step towards realization of networked society. While legacy wide-area wireless systems are highly dependent on network-side coordination, the level of consumed energy in signaling, as well as the expected increase in the number of IoT devices, makes such centralized approaches infeasible in future. Here, we address this problem by self-coordination for IoT networks through learning from past communications. To this end, we first study low-complexity distributed learning approaches applicable in IoT communications. Then, we present a learning solution to adapt communication parameters of devices to the environment for maximizing energy efficiency and reliability in data transmissions. Furthermore, leveraging tools from stochastic geometry, we evaluate the performance of proposed distributed learning solution against the centralized coordination. Finally, we analyze the interplay amongst energy efficiency, reliability of communications against noise and interference over data channel, and reliability against adversarial interference over data and feedback channels. The simulation results indicate that compared to the state of the art approaches, both energy efficiency and reliability in IoT communications could be significantly improved using the proposed learning approach. These promising results, which are achieved using lightweight learning, make our solution favorable in many low-cost low-power IoT applications.
