Distributed Radio Listening Synchronization Using Rendezvous Chain Based on TSCH

The TSCH mode of IEEE 802.15.4 is adopted as a network stack of IETF Working Group 6TiSCH for IoT environment with high reliability, low power and excellent network characteristics. In the TSCH network forming the network through frequency channel hopping, a fast network synchronization is possible by using the parallel rendezvous scheme which exchanges packets before synchronization the network. In this paper, we propose a distributed radio listening synchronization scheme that induces fast network formation by forming a rendezvous chain that divides the network radio listening channel based on the parallel rendezvous technique.
