A Doub-station Access Protocol based on CSMA/CA for Optical Wireless Networks
share
We propose a doub-station access protocol based on CSMA/CA (DS-CSMA/CA) for optical wireless local area networks (OWLANs), where two stations can transmit data frames to single destination at the same time, and the protocol can enable stations to avoid colliding with each other. Furthermore, we propose the state transmission model for DS-CSMA/CA and give the analysis of collision probability and throughput. We also propose the algorithm to optimize the parameters in proposed protocol. The result of numerical simulation shows remarkable enhancement of throughput for proposed protocol with optimal parameters compared to traditional CSMA/CA.
