Observability and controllability of wireless software components

Abstract

Software components embedded in wireless devices are subject to behavior which cannot be fully and realistically predicted. This calls for a runtime management infrastructure that is able to observe and control the components' states and to make their behaviors explicit, tangible and understandable, in any case and at any time. In this paper, we propose a framework for remotely administrating the functional behavior of software components deployed on wireless nodes. This framework is based on components which are locally managed by internal managers on the wireless side. The controllable nature of components relies on executable UML models that persist at runtime. On the administration side, models are replicated and synchronized with the models that constitute the inner workings of the wireless components. © IFIP International Federation for Information Processing 2007.
