The communication using visible light is the new trend in communication field where the different coloured light or different intensity of light is used to communicate. Why the visible light communication is more important in this era? It is because the already existing communication method has some difficulties and interference. The most of the existing communication systems uses radio frequency. In radio communication, information's such as sound, images are carried by radio waves. But this Radio Frequency [RF] communication has some disadvantages. It suffers from interference and high latency issues and the RF communication requires a separate setup for transmission and reception of radio waves. For overcoming these limitations, a new method is adopted ie, Visible Light Communication [VLC].
Recently, Consensus based Clock Synchronization (CCS) algorithms have gained much attention in wireless sensor networks due to its simplicity, distributed nature and robustness. Time synchronization in all networks either wired or wireless is important. It allows for successful communication between nodes on the network. It is, however, particularly vital for wireless networks. Wireless time synchronization is used for many different purposes including location, proximity, energy efficiency, and mobility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
