LiFi attocell access networks will be deployed everywhere to support diverse applications and service provisioning to various end-users. The LiFi infrastructure providers will need to offer LiFi access points (APs) resources as a service. This, however, requires a research challenge to be solved to dynamically and effectively allocate resources among service providers (SPs) , while guaranteeing performance isolation among them and their respective users. This paper introduces an autonomic resource slicing (virtualization) scheme, which realizes autonomic management and configuration of virtual APs, in a LiFi attocell access network, based on SPs and their users service requirements. The developed scheme comprises of traffic analysis and classification, a local AP controller, downlink and uplink slice resources manager, traffic measurement and information collection modules. It also contains a hybrid medium access protocol and an extended token bucket fair queueing algorithm to support uplink access virtualization and spectrum slicing. The proposed resource slicing scheme collects and analyzes the traffic statistics of the different applications supported on the slices defined in each LiFi AP and distributes the available resources fairly and proportionally among them. It uses a control algorithm to adjust the minimum contention window of user devices to achieve the target throughput and ensure airtime fairness among SPs and their users. The developed scheme has been extensively evaluated using OMNeT++. The obtained results show various resource slicing capabilities to support differentiated services and performance isolation.

“…19,25 The goodput defined by Equation 11 depends upon the packet size, total packets transmitted, and the duration of the simulation. 19 The average throughput and the delay results are given in Table 2. The Wi-Fi link in comparison provides communication over a longer distance but has low goodput.…”

“…The results illustrated compare the FIGURE 5 Mobility of 2 network models in simulation performance of the VLC and Wi-Fi networks. 19,25 The goodput defined by Equation 11 depends upon the packet size, total packets transmitted, and the duration of the simulation. In Figure 6A, the goodput for OOK shows poor performance as the VLC link starts to deteriorate after about 6 m between the transmitter and the receiver.…”

Visible light communication (VLC) is the branch of optical wireless communi-cations that uses light-emitting diodes for the dual purpose of illumination and very-high-speed data communication. The main motivation behind the current work is finding alternatives to the saturated radio frequency spectrum, radio frequency security issue, and vulnerability to interferences. The current work is aimed at developing a module for the physical layer of a VLC-based ad hoc network in network simulation 3. The VLC physical layer module is developed by using the optical signal modules available in the network simulator.The work also includes modelling of VLC-based transmitter, wireless optical channel, and the optical receiver. Furthermore, the implementation and evaluation of the VLC-based physical layer is carried out over a typical ad hoc network under different performance metrics. The designed ad hoc network is also tested under Wi-Fi module followed by its comparison with corresponding ad hoc network under VLC module. The comparison is based on bit error rate curves, system throughput, and gain in received signal-to-noise ratio mainly.Finally, the suitability of different modulation schemes is also investigated in the current work for both Wi-Fi-and VLC-based ad hoc networks. KEYWORDS ad hoc networks, bit error rate (BER), Li-Fi, modulation SCHEMES, network simulator, NS3, OOK, PAM, PHY layer, throughput, visible light communication (VLC), VPPM, 5G mobile communication | INTRODUCTIONIn the past decade, there has been a drastic increase in the demand for high-speed data communication services (cellular networks, smart TVs, cloud-based computing, high-definition video calling, and live streaming). The existing radio frequency (RF) wireless technologies have been the forefront of telecommunication, revolutionizing the voice and data communication. 1 However, because of saturation of RF spectrum, security issues, vulnerability to interferences, and hazards of RF, low-cost and reliable technologies are required to provide efficient data communication. The discovery and growing use of light-emitting diodes (LEDs) have boosted the research in visible light communication (VLC) technology. 2 Visible light communication is becoming an emerging green technology aimed to providing high data rates for short-range communication and easy deployment in hospitals, planes, and areas where traditional RF systems are less preferred. 3 The VLC salient features include license and interference-free spectrum (430THz-790THz), extremely large bandwidth, inherent security, compatibility with existing technologies, and high efficiency for positioning purposes due to its line-of-sight (LoS) feature. 4

“…Nonetheless, VLC performance evaluation remains poorly investigated and VLC simulation tools are still missing. The main efforts on simulating VLC systems have focused on indoor channel simulation [13], or on the 802.15.7 PHY [14,15] and MAC [16] layers. These approaches rely on classical network simulation frameworks, such as those used for wireless and ad hoc networks, e.g.…”

The use of LED-to-camera communication opens the door to a wide range of use cases and applications, with diverse requirements in terms of quality of service. However, while analytical models and simulation tools exist for all the major radio communication technologies, the only way of currently evaluating the performance of a network mechanism over LED-to-camera is to implement and test it. Our work aims to fill this gap by proposing a Markov-modulated Bernoulli process to model the wireless channel in LED-to-camera communications, which is shown to closely match experimental results. Based on this model, we develop and validate CamComSim, the first network simulator for LED-to-camera communications.
