Self-Organization and Self-Recovery System of Sensing Datas Based on LED Light Communication

In order to meet the special demands of sensing informations transmission in Internet of things,based on the lighting function of LED(Light Emitting Diode),the communication function of visible light,the self-organization and self-recovery functions of optical-fiber network basing infomation transmission are introduced.A new method for system nodes design and a Linux driving method for information links on sublayer was proposed,the route discovery algorithm and the implementation procedure of network protocols were discussed in detail.Finally,in the Embedded environment,the procedures of Ad Hoc network and self-coordination were programmed to debug and test the system.The experimental data verify the feasibility and completeness of the system architecture,transmission procedure and the core algorithm which establishes the theoretical basis for pratical research and development.
