RWiN: New Methodology for the Development of Reconfigurable WSN

This paper presents new challenges for the development of reconfigurable wireless sensor networks (RWSNs) that adapt dynamically their behaviors to their environment under different properties. An RWSN is a set of networked nodes that execute reconfigurable software tasks for the control of local sensors. We propose a new design methodology named RWiN of an RWSN using unified modeling language (UML) to analyze, construct, develop, and verify easily RWSN architectures. For that, we formulate a metamodel of RWSN based on UML to describe a zone-based architecture that uses a communication protocol for the optimization of distributed reconfigurations. To control the design complexity, we model each agent of this architecture by nested state machines. To verify the temporal constraints by communicating agents, each one is modeled by a timed automaton. The paper's contribution is applied to a case study, which is simulated with TRMSim-WSN and UPPAAL environment to expose the originality of this new architecture.
