Resumo
Context models that describe dynamic context-aware scenarios usually need to be frequently
updated. Some examples of situations that motivate these updates are the appearance
of new services and context providers, the mobility of the entities described in these
models, among others.
Generally, updates on models imply redevelopment of the architectural components of
context-aware systems based on these models. However, as these updates in dynamic
scenarios tend to be more frequent, it is desirable that they occur at runtime.
This dissertation presents an infrastructure for dynamic management of context models
based on the fundamentals of complex event processing, or CEP. This infrastructure
allows the fundamental abstractions from which a model is built to be updated at runtime.
As these updates can impact systems based on the updated models, this dissertation
identifies and analyzes these impacts, which are reproduced in a case study that aims
to evaluate the proposed infrastructure by demonstrating how it deals with the impacts
mentioned.
