Special Issue Information

Dear Colleagues,

Recent advances in computing hardware and machine learning algorithms have brought innovative development in a wide range of technologies, such as recommendation systems, self-driving vehicles, and chatbots, by addressing intractable challenges with traditional approaches. In this regard, the machine learning technique is expected to play an important role for dealing with the ever-increasing demand for connectivity in future wireless networks. There is a critical need to develop intelligent communication techniques and communication-aware machine learning techniques for mobile and sensor networks.

The objective of this Special Issue is to address, discuss, and present novel machine learning-based wireless communication techniques for future wireless networks. The topics of the Special Issue include, but are not limited to the followings:

  • Machine learning for Internet of things (IoT) and massive connectivity;
  • Machine learning for ultra-reliable and low latency communications (URLLC);
  • Machine learning for massive MIMO;
  • Machine learning driven novel waveform designs;
  • Machine learning for distributed communications;
  • Machine learning for communication resource allocation;
  • Machine learning for user scheduling;
  • Communication-aware federated learning.

Recently, federated learning (FL) has been receiving great attention as an effective machine learning method to avoid the security issue in raw data collection, as well as to distribute the computing load to edge devices. However, even though wireless communication is an essential component for implementing FL in edge networks, there have been few works that analyze the effect of wireless networks on FL. In this paper, we investigate FL in small-cell networks where multiple base stations (BSs) and users are located according to a homogeneous Poisson point process (PPP) with different densities. We comprehensively analyze the effects of geographic node deployment on the model aggregation in FL on the basis of stochastic geometry-based analysis. We derive the closed-form expressions of coverage probability with tractable approximations and discuss the minimum required BS density for achieving a target model aggregation rate in small-cell networks. Our analysis and simulation results provide insightful information for understanding the behaviors of FL in small-cell networks; these can be exploited as a guideline for designing the network facilitating wireless FL.

With the advent of the Internet of Things (IoT) era, a wide array of wireless sensors supporting the IoT have proliferated. As key elements for enabling the IoT, wireless sensor nodes require minimal energy consumption and low device complexity. In particular, energy-efficient resource scheduling is critical in maintaining a network of wireless sensor nodes, since the energy-intensive processing of wireless sensor nodes and their interactions is too complicated to control. In this study, we present a practical deep Q-network (DQN)-based packet scheduling algorithm that coordinates the transmissions of multiple IoT devices. The scheduling algorithm dynamically adjusts the connection interval (CI) and the number of packets transmitted by each node within the interval. Through various experiments, we verify how effectively the proposed scheduler improves energy efficiency and handles the time-varying nature of the network environment. Moreover, we attempt to gain insight into the optimized packet scheduler by analyzing the policy of the DQN scheduler. The experimental results show that the proposed scheduling algorithm can further prolong a network’s lifetime in a dynamic network environment in comparison with that in other alternative schemes while ensuring the quality of service (QoS).
