Optical Switching based on Position-Tracking algorithm to Realize "Moving Cells" in a RoF Network

When today's commuters in the train want to access broadband multimedia services. However, the classical solutions such as WLAN and UMTS are not sufficient to provide a high bandwidth to train users. In this paper, we propose optical switching based on position-tracking (OSPT) algorithm to realize "moving cells" in a RoF network. The proposed OSPT algorithm can reduce the latency time and increase the channel utilization in the optical switching architecture in train communication network.
