Paper Abstract

Identification (ID) systems utilizing visible light are an interesting topic, and have been attracting the growing attention of researchers recently. However, LED transmitters with a unique ID illuminate a limited coverage area, therefore, limiting the communication coverage. In order to extend the communication coverage, we proposed wireless mesh networks (WMNs) for relaying the information. Routing operations in WMNs might be challenging due to various factors. In this paper we analyze the link error probability and optical power loss. Based on our proposed network topology, we further found an effective scheme, multi-stage parallel interference cancellation (PIC), to alleviate the negative impacts due to interference which comes from multi-user data transmission.
