Issue Date: | 2015 | Journal: | IEEE CITS 2015 - 2015 International Conference on Computer, Information and Telecommunication Systems | Conference: | International Conference on Computer, Information and Telecommunication Systems, IEEE CITS 2015 | Abstract: | IEEE 802.15.7 is a physical and MAC layer standard for visible light communication (VLC). A slotted CSMA/CA MAC procedure is defined in the standard to coordinate optical channel access for multiple wireless devices. This CSMA/CA process does not provide any hidden node avoidance mechanisms, thus potentially leading to severe performance degradation in the presence of hidden nodes due to collisions. In this paper, we analyze the effect of hidden nodes on a VLC network in the star topology. We implement a simulator and analyze VLC performance in terms of parameters like end-to-end goodput and packet loss rate. The impact of the hidden node problem in network performance is evaluated by comparing simulation results. | URI: | http://hdl.handle.net/10553/43107 | ISBN: | 9781467369459 | ISSN: | 2326-2338 | DOI: | 10.1109/CITS.2015.7297726 | Source: | 2015 International Conference On Computer, Information And Telecommunication Systems (Cits)[ISSN 2326-2338], (2015) |
