Pairing Strategy for using Multiple Channels in Minimal Cell of 6TiSCH Network

Time Slotted Channel Hopping (TSCH) is a Medium Access Control (MAC) technology defined in the IEEE 802.15.4e standard. In IPv6 over the TSCH mode of IEEE 802.15.4e (6TiSCH) networks, the minimal cell for exchanging control packets operates on a single channel, leading to increased node synchronization time and inefficient network topology formation as the network scales up. So, we propose a pairing strategy, which enables the use of multiple channels in the minimal cell. We evaluated the pairing strategy in the 6TiSCH simulator. In congested scenarios, it constructs a more efficient topology compared to traditional 6TiSCH and Time-Variant RGB Mode (TRGB).
