To foster the further developments in this direction, the stratified model of the Internet of Things infrastructure has been proposed. There are distinguished three hierarchical layers: the lowest one is represented with web services, the intermediate one-with usage scenarios, the upper layer-with applicability domain of the Internet of Things solution. The model is based on the Temporal Logic of Actions and corresponding TLA+ formalism. To check the specification, created with respect to the proposed model, the TLC model checker has been used. Two approaches to automated TLC-verification have been utilized-model checking by way of breadth-first search and by way of depth-first search. The smart home scenario has been considered. ER -
