Automated Analysis of MUTEX Algorithms with FASE

In this paper we study the liveness of several MUTEX solutions by representing them as processes in PAFAS s, a CCS-like process algebra with a specific operator for modelling non-blocking reading behaviours. Verification is carried out using the tool FASE, exploiting a correspondence between violations of the liveness property and a special kind of cycles (called catastrophic cycles) in some transition system. We also compare our approach with others in the literature. The aim of this paper is twofold: on the one hand, we want to demonstrate the applicability of FASE to some concrete, meaningful examples; on the other hand, we want to study the impact of introducing non-blocking behaviours in modelling concurrent systems.Comment: In Proceedings GandALF 2011, arXiv:1106.081

An Integration Platform for Private Assisted Houses

A Private Assisted House aims to define a novel care model focusing on the changing needs of people to promote active life expectancy. This raises the need of personalization in the design and development of Smart Home, so starting from users requirements we stress the need of integration suitable to support such changing requirements. In this paper we discuss Private Assisted House integration platform focusing on its conceptual model and reference architecture. The platform is defined around a set of smart objects managed by a home gateway that communicate with a Cloud Center. This organization provide two kinds of processing: (i) local to the house, and (ii) remote. The local processing involves events, triggers, commands and automations managed directly for the gateway. The remote processing implies communication from the house to the Cloud Center that can provide intelligence to the house using high-level applications that use data correlation to perform specific tasks
