Distributed Channel Hopping Radio listening Synchronization Device and Method Using Rendezvous Chain Based

摘要

The present invention provides a TSCH-based rendezvous chain that exchanges ERB (Enhanced Rendezvous Beacon) packets before joining the network to form a rendezvous chain, and each communication node device divides and listens to channels to increase the probability of receiving EB packets. A packet reception module that changes a reception channel, manages EB/ERB packets, receives ERBs, and transmits EB packets to rendezvous neighbors; a transmission channel change and EB priority. An EB transmission module that manages a channel vector table; a channel vector management module that manages a channel vector table and stores it in a channel vector table by modifying when a channel is divided; manages the rendezvous neighbor table according to the channel vector determination result of the channel vector management module, It includes a rendezvous neighbor management module for adding and deleting rendezvous neighbors and managing rendezvous neighbor information; an ERB transmission module for managing ERB packet transmission by changing a transmission channel.
