On the Performance of a Cooperative PLC-VLC Indoor Broadcasting System Consisting of Mobile User Nodes for IoT Networks.

A novel mixed cooperative relay assisted indoor power line communication - visible light communication (PLC-VLC) system for indoor broadcasting purpose consisting of mobile end user nodes for Internet of Things (IoT) network is presented in this study. Here, the PLC link acts as a backbone system to the VLC link by connecting to the latter with the help of decode and forward (DF) relay. The channel gain of the VLC systems is considered to be a function of user mobility which is modeled using random waypoint (RWP) mobility model. We present novel expressions for probability density function and cumulative distribution function for the equivalent end to end instantaneous signal to noise ratio (SNR) for this cooperative system. Using these derived statistics, we further evaluate the performance of the system under consideration in terms of link failure probability and average bit error rate. [ABSTRACT FROM AUTHOR]
