Vertical handover in optical wireless heterogeneous networks

Heterogeneous networks are now widely deployed to improve the coverage rate for large area and increase the communication capacity in small area coverage. Indoor optical wireless or Li-Fi satisfies high capacity demand in density scenario, without any interference to existing radio frequency communication. It brought new challenges to deal with handover for heterogeneous networks when optical wireless access attachment points existed. In this article, we introduced vertical handover and designed a vertical handover algorithm for a typical optical wireless scenario.
