Incorporate mobility management into industrial wireless sensor networks

Abstract

Technologies dedicated radio infrastructure deployments are no longer adequate to ensure large-scale, low-cost, and reliable communications with the growing adoption of scattered wireless technologies for current services. The goal of this article is to allow the deployment of a radio network infrastructure for numerous client applications, hence building the Internet of Things (IoT), IEEE established IEEE 802.15.4e time slotted channel hopping (TSCH), an extremely efficient, reliable, and predictable time-frequency enabled medium access control (MAC) protocol for the industrial sector, on top of the low-power IEEE 802.15.4 radio. A MAC communication schedule may be constructed from an IEEE 802.15.4e TSCH communication schedule. The IEEE 802.15.4e TSCH definition, on the other hand, makes no mention of how such scheduling may be generated, modified, or maintained. It also has no jurisdiction over the unit in charge of these obligations. This means that the standard is missing the required scheduling mechanism. To meet this demand, several communication scheduling approaches have been presented in the literature. We first establish a novel decentralized communication scheduling approach called mobile scheduling updated TSCH (MSU-TSCH), which implies that network traffic can move in any direction rather than from leave nodes to the root, in this study. The MSU-TSCH algorithm tries to plan time slots by selecting the node that is nearest to the user. While selecting a nearby node, it seeks to assign a roughly equal quantity of dedicated time slots to each member node (or member neighbor). Other scheduling algorithms may not be able to construct better schedules with neighbor nodes as a consequence.
