New computing paradigms like the Internet of Things (IoT) and the Web of Things (WoT) are making smart spaces more and more common. One of the problems in this context is to enable access to the resources of the smart spaces by the different entities that compose it, considering different access levels. This paper aims to present and simulate the use of an algorithm and an access policies specification language for shared resources in a ubiquitous computing scenario. The simulation was performed under the formalities of the Discrete Event Systems Specification (DEVS) in the MS4 Modeling Environment (MS4 Me). We were able to conclude that both the language and the algorithm are valid approaches to handle concurrent access to smart objects resulting from the smart spaces overlapping.
