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.

IoT网络中由移动用户节点组成的PLC-VLC合作室内广播系统的性能研究

这项研究提出了一种新颖的混合协作中继辅助室内电力线通信-室内广播目的的可见光通信（PLC-VLC）系统，该系统由用于物联网（IoT）网络的移动最终用户节点组成。在此，PLC链接通过VCL链接通过解码和转发（DF）中继与VLC链接充当骨干系统。VLC系统的信道增益被认为是用户移动性的函数，它是使用随机航点（RWP）移动性模型建模的。我们为这种协作系统的等效端到端瞬时信噪比（SNR）提供了概率密度函数和累积分布函数的新颖表达式。使用这些衍生的统计数据，
