Abstract

The exponential growth in mobile devices has led to increasing demand for wireless services [1], and most of mobile data traffic is generated indoors [2], so people have a demanding need for fast wireless transmission indoors. However, The current radio frequency-based wireless communication spectrum is close to saturation[3], and it can’t meet people’s requirements in some specific scenarios, such as medical and industrial environments[4]. Therefore, alternative communication methods: Visible light communication (VLC), powerline communication, and fusion technologies, are considered to offload the overcrowded wireless spectrum bandwidth. In my thesis, I proposed a hybrid LiFi-PLC network. It uses VLC as an access network and the infrastructure of Power line communications (PLC) as a backhaul, which interconnects the VLC front-ends to the external networks. The envisioned hybrid network can provide communication without additional infrastructure costs due to the ubiquity of infrastructure. However, in the LiFi-PLC integration, some problems still exist, such as how to design the structure of the integrated network to reduce the modification of the indoor layout and how to reduce the complexity of the network protocol[5]. Besides, as there is no end-to-end analysis of such hybrid systems, the throughput analysis of the hybrid PLC-VLC network also needs to be performed. To verify the functionality and perform end-to-end analysis of the LiFi-PLC network, I modified the PLC and VLC modules proposed by [6] and [2] and tested The hybrid network in the ns-3 simulation environment with the parameters set according to the latest standard. The simulation shows that the hybrid network can achieve a stable throughput of 11Mbps in the test environment and an average throughput greater than 1Mbps in the case of 9 end users, which can meet the general requirements for indoor communication. The results showed that the envisioned LiFi-PLC network could be a promising alternative solution for wireless communication.
