Self-adaptable anti-interference scheme based on light-path blocking in an hybrid WiFi-VLC network.

Abstract

In this paper, a self-adaptable anti-interference scheme in a hybrid wireless fidelity (WiFi) and visible light communication (VLC) network is firstly proposed by light-path blocking. By human behavior characteristics, a user-device position relationship model is constructed to determine users' orientations. By the model, a strategy of choosing access points (AP) is present. By the strategy, communicating APs can be self-adaptively selected to match them with users' orientations. In the scheme, interference signals can be effectively blocked through the user's body to ensure normal communication. Finally,the effectiveness of the scheme has been demonstrated with simulations. Also, the scheme has its comparative advantages of not only saving energy, increasing SINR and lifting the availability of the hybrid WiFi-VLC network but also having faster response speed of network, higher efficiency of user access, easier implementation and lower cost.
