Abstract
Broadband applications vary from entertainment, medicine, internet browsing, multimedia, voip, which are the essentials of internet of things (IOT). Various technologies s have been deployed for the provision of these applications. All except the power line communication (PLC) technology requires a new installation. The PLC technology utilises the existing electrical network as is medium. Hence, broadband applications are provided by connecting to the electrical power socketoutlets. The power network (powerline) degrades the broadband signal as it traverses the line, owing to the characteristics off the line which is not designed for broadband signal propagation. This degradation results in noise and attenuation. Cooperative fixed relaying have been deployed to mitigate the degradation. In this paper, deployment of multiple relays for the purpose of selecting the relay with the best channel characteristic was considered for the cooperative scheme in broadband over power line system performance upgrade. A selection algorithm using the best instantaneous SNR was developed. The relay with the best instantaneous SNR is selected for cooperation of the source modem with the destination mode. The channel capacity and attenuation performance were evaluated. Comparison of these metrics for the system was compared to those of the fixed cooperative relaying scheme and those of MIMO. The selective relaying scheme achieved an improved performance.
