Mean Holding Time in Sync of Lossy IEEE 802.15.4e TSCH Networks for Industrial IOT Applications

IEEE 802.15.4e network aims at providing highly reliable communication links via time slotted channel hopping (TSCH) technology for lossy wireless channels. In such network, all nodes remain synchronized via message exchange periodically to compensate for the clock drift. In this paper, we derive theoretical average time for a node to remain in synchronized status with its parent node under the noisy channel scenario. Carried-out simulation results verify the correctness of our derived theoretical results.
