Self-adaptive Middleware in Ubiquitous Computing Environments
Qinma Kang · 2009
The inherent complexity of ubiquitous computing poses many new challenges for software infrastructure,which needs urgently the adaptive middleware.This paper proposed a self-adaptive middleware in ubiquitous computing environments,which is composed of the three meta-models,namely the interface,framework and context meta-models.The design and implementation on CAR component platform were presented.The interface meta-model provides access to the services and the internal information and state of a component in terms of asynchronous and synchronous interfaces.The context meta-model represents context information in component object and mask distribution problems in ubiquitous computing environment based asynchronous event notification.The framework meta-model classifies and mana-ges component,makes changes to middleware structures and behaviors according to the changing runtime environments.At last,the software system meets the dynamic self-adaptive requirement in ubiquitous computing environments.
