Aspects of Ambient Assisted Living and Its Applications
by a predefined protocol and interaction between actors and the system. The following
procedure is applied recursively for the subsystem.
1. Its architecture is defined by UML-RT context diagram
2. Its internal structure is described by composite structure diagrams
3. For each component in the subsystem
a. if the component is composite, then jump to step i
b. else, if the component is basic, then capture its timed behavior by timed state
diagram (Benghazi et al. 2012).
Figure 8.17 shows an example model setup using MEDISTAM_RT. It consists of two capsules C1 and C2 for which activity is defined. The system also considers the temporal consistency of the basic capsules and their protocols for coordination between them through
message passing. Thus, the behavior of the ports (edges of communication point) determines the pattern of interaction in time-constrained message passing to the environment.
8.11 Cognitive AAL
Cognitive architecture uses a distributed intelligent system for controlling and decisionmaking of an ambient intelligence system (Peter Ivanov et al. 2015). Neurodegenerative
diseases (Antonio Coronato and Giuseppe De Pietro 2012) are progressive and very hard to
diagnose in its early stages. Progressive impairment in the activities of daily living, as well
