Abstract
This paper deals with software validation of flexible discrete-event systems. A reconfiguration scenario is any run-time adaptation of the software execution according to user requirements. Nevertheless, since several behaviors can be redundant from an execution to another, using the object constraint language (OCL) is not useful to specify all constraints that should be satisfied by a system. We propose an extension of OCL named reconfigurable OCL for improving the specification and validation of constraints related to different execution scenarios of a system. An ROCL metamodel is proposed with formal syntax and semantics. This solution gains in terms of validation time and quick expressions of constraints. We apply the proposed extended language to reconfigurable wireless sensor networks to highlight the benefits of this contribution.
