A fast joining scheme based on channel quality for IEEE802.15.4e TSCH in severe interference environment

摘要

Time Slotted Channel Hopping is one of the access behavior technique defined in IEEE 802.15.4e standard. In this paper, we focus on TSCH's network formation process in severe interference environment. In a congested environment, the time to join the network increases and this leads to energy consumption and delay control signal for real-time system. To overcome this issue, we suggest Fast Joining scheme based on Channel Quality estimation(FJCQ). FJCQ provides short joining time even in severe congestion situations. The scheme is implemented in real nodes and shows its performance by comparison with other approaches.
