Random weather phenomena in free-space optical - FTTx communication system

In the last few decades, optical wireless communication became an essential technology in various applications. Researchers have paid more attention to achieving high bandwidth and low loss. However, the random weather phenomena cause attenuation of optical signals, thus will decrease the bandwidth in optical wireless communication. In this article, we investigate a hybrid free-space optical (FSO) and fiber-to-the-x (FTTx) communications link based on wavelength-division multiple access (WDMA) over different random weather phenomena that operate over different wavelengths. The performance of the hybrid FSO-FTTx system is evaluated under clear sky weather phenomena, heavy rain weather phenomena, and heavy haze weather phenomena based on BER and Q-Factor measurements. The results show that we can transmit 140 Gbit/s data over 9650 meters a hybrid link under the clear sky and heavy rain weather phenomena, 3950 meters over. Additionally, the transmission of 140 Gbit/s data can be achieved for 1450 meters under the heavy haze weather phenomenon

Using AI in wireless communication system for resource management and optimisation

The existence of Artificial Intelligence (AI) can be seen in everyday scenarios. Nowadays, the produced data by both machine and human is overwhelming in which exceeded the ability of humans to understand and digest to make decisions depending on that data. Thus, a hand of help from AI is needed to overcome such challenges. The 5G LTE communication system is a promising solution to provide a high user experience in terms of the provided speed, amount of data, and cost. However, and due to its complexity, the technology of LTE needs some improvement in terms of resource management and optimization. With the aid of AI, these two challenges can be overcome. In this paper, the AI represented by improved Q-learning algorithm with the Self-Organizing Network (SON) concept in LTE will be used to manage and optimize Handover (HO) parameters and process in the system. The ns-3 simulator result shows that AI managed to improve and optimize the LTE system performance

WLAN performance evaluation in different wireless access techniques (DCF, PCF, HCF)

IEEE 802.11x Wireless Local-Area-Network (WLAN) considered a powerful solution for the last mile wireless broadband(BB) access. WLAN becomes important element in 4G and 5G mobile networks because it can provide services to mobile users in areas not covered by eNBs. However, the 802.11 legacy protocol doesn’t support delay-sensitive services like VoIP because it adopts the best-effort method. In 2001 IEEE 802.11e standard was proposed to deploy QoS with new access techniques introduction. There are many parameters related to MAC layer which affect the WLAN network performance from the prospective of delay, and throughput. This study presents performance evaluation of voice traffic and FTP traffic in IEEE802.11 legacy protocol WLAN and IEEE802.11e WLAN via OPNET computer simulation. Network performance will be tested against different MAC access protocols and different MAC parameters
