“…To withstand mmWave channel impairments, the use of antenna beamforming using either analogue beamforming or hybrid precoding was studied in literature as given in [12,16,17]. For mmWave wireless local area network applications, variety of Wi-Fi/WiGig interworking schemes can be also found in the literature [4,[18][19][20].…”

“…Two promising technologies are introduced as key enablers for future fifth-generation (5G) networks and beyond, namely the millimetre wave (mmWave) communications and the nonorthogonal multiple access (NOMA) [1,2]. The communication in the mmWave band, 30-300 GHz, is introduced to highly boost the capacity of future 5 G networks by utilising the large swath of available spectrum in this band [3,4]. On the other side, NOMA aims to increase the spectrum efficiency of future 5 G networks via multiplexing multiple users' signals in the power/code domain using the same resource block, e.g.…”

The integration of millimeter wave (mmWave) and low frequency interfaces brings an unique opportunity to unify the communications and positioning technologies in the future wireless heterogeneous networks (HetNets), which offer great potential for efficient handover using location awareness, hence a location-aware handover (LHO). Targeting a self-organized communication system with autonomous vehicles, we conduct and describe an experimental and analytical study on the LHO using a mmWave-enabled robotic platform in a multi-radio environment. Compared to the conventional received signal strength indicator (RSSI)-based handover, the studied LHO not only improves the achievable throughput, but also enhances the wireless link robustness for the industrial Internet-of-things (IIoT)-oriented applications. In terms of acquiring location awareness, a geometry-based positioning (GBP) algorithm is proposed and implemented in both simulation and experiments, where its achievable accuracy is assessed and tested. Based on the performed experiments, the location-related measurements acquired by the robot are not accurate enough for the standalone-GBP algorithm to provide an accurate location awareness to perform a reliable handover. Nevertheless, we demonstrate that by combining the GBP with the dead reckoning, more accurate location awareness becomes achievable, the LHO can therefore be performed in a more optimized manner compared to the conventional RSSI-based handover scheme, and is therefore able to achieve approximately twice as high average throughput in certain scenarios. Our study confirms that the achieved location awareness, if accurate enough, could enable an efficient handover scheme, further enhancing the autonomous features in the HetNets.

“…In [21], a multi‐band MAC protocol for Wi‐Fi/mmWave WLANs was proposed, where FST between both bands was utilised to transfer the data communication session from the congested Wi‐Fi band to the mmWave band while considering mmWave path availability. In [22], conventional FST is utilised, where the multimedia service quality is adapted to either Wi‐Fi or WiGig links when FST occurs. In [23], power allocation and packet buffering were explored for video transmissions in FST Wi‐Fi/WiGig capable devices.…”

Novel fast session transfer decision‐making algorithm using fuzzy logic for Wi‐Fi/WiGig wireless local area networks

Fast session transfer (FST) is introduced by wireless gigabit (WiGig) standards to transfer the data communication session among wireless fidelity (Wi‐Fi) and WiGig channels based on the availability. In the conventional Wi‐Fi/WiGig FST decision‐making, the session of data transmission is transferred from Wi‐Fi to WiGig whenever it is possible regardless of the traffic loads on both bands and the expected WiGig blocking probability. Also, WiGig to Wi‐Fi FST occurs whenever the WiGig signal is lost even if the WiGig link is undergoing an instant path blocking. This results in Wi‐Fi/WiGig load imbalance as well as large average delay in user data delivery. In this study, a novel Wi‐Fi/WiGig FST decision‐making algorithm is proposed utilising fuzzy logic while considering the coverage probability of the WiGig link, the sizes of the users' remaining messages relative to the available data rates of both bands, and the probability of WiGig path blocking. Furthermore, a WiGig interruption‐classification methodology is proposed to detect the occurrence of the WiGig instant path blocking and then decide if it is better to wait for WiGig signal recovery or immediately transfer to Wi‐Fi. Simulation analysis demonstrates the effectiveness of the proposed Wi‐Fi/WiGig FST decision‐making algorithm, over the conventional one.
