- Abstract:
- Monitoring of activities of elderly and intelligent decisions about their living environment is a key challenge in smart environments. In the case of such challenges, correctness of system performance is highly dependent on how the model is designed. In the ambient intelligence (AMI) modeling, formal modeling is one of the best approaches because it supports certainty. In addition, time, location and mobility in AMI are crucial requirements, particularly in emergency treatment services. Ambient calculus is a formalism for describing mobility, process migration and message transfer, but it cannot express metric time duration. In this paper we propose an extension of ambient calculus with time interval to have a more complete modelling of AMI and enhancement behavioral modeling in proposed calculus which support fundamental requirements. This approach accommodates for scenarios which have unknown end of time. Moreover, we express a case study using our proposed notations. In the end, we use of hierarchical timed automata (HTA) for symbolic semantics. In fact, our proposed calculus semantic rules are translated into HTA and we doing temporal and spatial verification of scenarios with our transformation semantic by one of the famous tools model checking UPPAAL
