“…The work by Xu et al (2021) proposed successive interference cancellation using a multicontention queue that reduces wasted time due to channel contention in CSMA/CA. The performance of OFDMA-based CSMA/CA techniques for multiuser access was presented by Dube and Walingo (2020) and the results showed better throughput and delay in lossy communication links.…”

A resource sharing in power line communications (PLC) for the home network is restricted by the channel assignment techniques which decide who has the right to gain access to send data. The channel assignment techniques include contention-free and contention-based. The former requires high synchronization due to the deterministic round-trip time. Besides, contention-based utilizes CSMA/CA techniques that allow stations in a network to compete for channel access and are suitable for decentralized network topology. However, a trade-off exists between the number of stations required to gain access versus system efficiency. Whilst some research has been carried out on CSMA/CA resource sharing techniques that allow only one user to transmit, there is very little work done on multiuser access to optimize system efficiency and reduce collisions in a network. The purpose of the current study was to review the CSMA/CA techniques for resource sharing to improve system efficiency in power line communications. In carrying out this study, a systematic literature review methodology to evaluate different related works and determine the most suitable approach to allow multiuser channel access was used. The study further demonstrated the impact multichannel access has on system efficiency. In addition, the study provides recommendations for future research.

With the development of technology, the 5th-generation mobile communication technology is becoming more and more mature, and the LTE wireless network is in the peak of application. Although the current wireless propagation model has good adaptability, the prediction accuracy of signal propagation in various specific environments is low; therefore, the wireless propagation model needs to be corrected. The LTE wireless network propagation model was optimised by using the neural network algorithm and corrected by combining with the actual geomorphic characteristics of the experimental area so as to improve the accuracy of simulation prediction of the signal in the service coverage area by the propagation model and provide reference for wireless network planning.
