A Survey on Real‐Time Communications in Wireless Sensor Networks
Wireless Communications and Mobile Computing, Volume 2017, Issue 1, 2017., 2017 Generally, various traffic requirements in wireless sensor network are mostly dependent on specific application types, that is, event‐driven, continuous, and query‐driven types. In these applications, real‐time delivery is one of the important research challenges. However, due to harsh networking environment around a node, many researchers usually take

ReSF: Recurrent Low-Latency Scheduling in IEEE 802.15.4e TSCH networks [PDF]
Ad Hoc Networks, 2018 Abstract The recent increase of connected devices has triggered countless Internet-of-Things applications to emerge. By using the Time-Slotted Channel Hopping (TSCH) mode of the IEEE 802.15.4e MAC layer, wireless multi-hop networks enable highly reliable and low-power communication, supporting mission-critical and industrial applications.
