Special Issue Information

Dear Colleagues,

With the advent of 5G, agile machine-type communications (MTC) may finally become a reality. The three pillars of technological improvements: higher throughput, significantly increased number of connected devices, and especially lower latency are seen as major enabling factors in the wider deployment of mission-critical applications (MCAs).  These applications range from autonomous vehicles and drones, haptic communications over 5G,  electrical grid, and industrial automation to smart cities  and medical applications, and are typically characterized by the need for extremely reliable transport in addition to low latency and potentially high bandwidth. One of the main challenges for supporting MCA-type services lies in the creation of overall network architectures that adapt to fluctuating traffic patterns and enable overall high adaptability that spans not only the radio access layer and core network services but also extends to edge and core computing that are essential in supporting MCAs.

The objective of this Special Issue is to bring together state-of-the-art contributions related to 5G-based mission-critical applications and services covering topics such as the development and operation of MCA/M2M applications using the 5G service stack, the role of NFV and network slicing in mission-critical communications, exposing the network to the application (programmable RAN, core network interfaces, transport network configuration with SDN, etc.), over-the-top approaches to MCAs, transport protocols and APIs  for MCAs, testbeds to validate 5G MCAs, lessons from trials with MCAs, the impact of multiple operators and roaming in 5G applications, challenges from MCA regulation and governance, as well as security and privacy issues related to MCAs.

This Special Issue is connected to the activities in the European project 5GENESIS (under the umbrella of 5G PPP) and the US project COSMOS (under the umbrella of PAWR). An email to the Guest Editors with the tentative title and abstract is expected before submission.

In this paper, a new WHT-LWT-GFDM waveform obtained by combining Walsh–Hadamard Transform (WHT), Lifting Wavelet Transform (LWT), and Generalized Frequency Division Multiplexing (GFDM) is presented for use in next-generation wireless communication systems. The proposed approach meets the requirement of 5th-generation (5G) and beyond communication schemes in terms of low latency, low peak-to-average-power ratio (PAPR), and low bit-error rate (BER). To verify the performance of the presented waveform, PAPR and BER simulation results were obtained in additive white Gaussian noise (AWGN) and flat Rayleigh fading channels, and the performance of the proposed system was compared with conventional Orthogonal Frequency Division Multiplexing (OFDM), GFDM, and Walsh–Hadamard transform-based GFDM (WHT-GFDM). Simulation results show that the proposed waveform achieves the best BER and PAPR performances and it provides considerable performance gains over the conventional waveforms. Full article

With the emergence of 5G networks and the stringent Quality of Service (QoS) requirements of Mission-Critical Applications (MCAs), co-existing networks are expected to deliver higher-speed connections, enhanced reliability, and lower latency. IEEE 802.11 networks, which co-exist with 5G, continue to be the access choice for indoor networks. However, traditional IEEE 802.11 networks lack sufficient reliability and they have non-deterministic latency. To dynamically control resources in IEEE 802.11 networks, in this paper we propose a delay-aware approach for Medium Access Control (MAC) management via airtime-based network slicing and traffic shaping, as well as user association while using Multi-Criteria Decision Analysis (MCDA). To fulfill the QoS requirements, we use Software-Defined Networking (SDN) for airtime-based network slicing and seamless handovers at the Software-Defined Radio Access Network (SD-RAN), while traffic shaping is done at the Stations (STAs). In addition to throughput, channel utilization, and signal strength, our approach monitors the queueing delay at the Access Points (APs) and uses it for centralized network management. We evaluate our approach in a testbed composed of APs controlled by SD-RAN and SDN controllers, with STAs under different workload combinations. Our results show that, in addition to load balancing flows across APs, our approach avoids the ping-pong effect while enhancing the QoS delivery at runtime. Under varying traffic demands, our approach maintains the queueing delay requirements of 5 ms for most of the experiment run, hence drawing closer to MCA requirements. Full article
