Special Issue Information

Dear Colleagues,

Intelligent sensing has been receiving a lot of attention from the industry, academia and the general public due to its numerous applications in enhancing service delivery of businesses and improving socio-economic lives of communities. Accordingly, 5G cellular networks are being designed to support massive machine-type communication (mMTC) and enhanced Mobile Broadband (eMBB) applications, in addition to Ultra-Reliable and Low Latency Communication (URLLC). These KPIs will allow 5G networks to support up to 1 million devices per square kilometer and the huge amount of data that will be generated by intelligent sensors.

The proposed special issue will comprise of a collection of the latest high-quality technical research and industrial papers with novel results covering intelligent sensors for 5G-and-beyond networks. The main aim of this special issue is to provide a platform for the dissemination of major research challenges and achievements on this topic. Theoretical investigations as well as experiments/demos are welcome.

Potential topics include, but are not limited to

  • Communication algorithms, protocols, standards and architectures for IoT and sensor networks
  • Massive IoT/massive machine type communication
  • Low power wide area (LPWA) technologies such as NB-IoT, Lora, etc.
  • Data analytics for intelligent sensing networks
  • Novel geo-location techniques for intelligent sensors

Due to large spectral efficiency and low power consumption, the Massive Multiple-Input-Multiple-Output (MIMO) became a promising technology for the 5G system. However, pilot contamination (PC) limits the performance of massive MIMO systems. Therefore, two pilot scheduling schemes (i.e., Fractional Pilot Reuse (FPR) and asynchronous fractional pilot scheduling scheme (AFPS)) are proposed, which significantly mitigated the PC in the uplink time division duplex (TDD) massive MIMO system. In the FPR scheme, all the users are distributed into the central cell and edge cell users depending upon their signal to interference plus noise ratio (SINR). Further, the capacity of central and edge users is derived in terms of sum-rate, and the ideal number of the pilot is calculated which significantly maximized the sum rate. In the proposed AFPS scheme, the users are grouped into central users and edge users depending upon the interference they receive. The central users are assigned the same set of pilots because these users are less affected by interference, while the edge users are assigned the orthogonal pilots because these users are severely affected by interference. Consequently, the pilot overhead is reduced and inter-cell interference (ICI) is minimized. Further, results verify that the proposed schemes outperform the previous proposed traditional schemes, in terms of improved sum rates. Full article

The global bandwidth shortage in the wireless communication sector has motivated the study and exploration of wireless access technology known as massive Multiple-Input Multiple-Output (MIMO). Massive MIMO is one of the key enabling technology for next-generation networks, which groups together antennas at both transmitter and the receiver to provide high spectral and energy efficiency using relatively simple processing. Obtaining a better understating of the massive MIMO system to overcome the fundamental issues of this technology is vital for the successful deployment of 5G—and beyond—networks to realize various applications of the intelligent sensing system. In this paper, we present a comprehensive overview of the key enabling technologies required for 5G and 6G networks, highlighting the massive MIMO systems. We discuss all the fundamental challenges related to pilot contamination, channel estimation, precoding, user scheduling, energy efficiency, and signal detection in a massive MIMO system and discuss some state-of-the-art mitigation techniques. We outline recent trends such as terahertz communication, ultra massive MIMO (UM-MIMO), visible light communication (VLC), machine learning, and deep learning for massive MIMO systems. Additionally, we discuss crucial open research issues that direct future research in massive MIMO systems for 5G and beyond networks. Full article
