Abstract
The required autonomy and the growth of the complexity of wireless sensor networks (WSNs) systems give the reconfiguration a big importance. Thus, the integration of reconfiguration scenarios (node level or network level reconfiguration) in the development cycle of WSNs system is required to offer an efficient reaction to environment variability. In this direction, existing model based design approaches of reconfigurable WSNs are limited to the design of behavioral reconfiguration techniques which bring adjustment of the system's parameters or update some functionalities. However, network reconfiguration which presents an important ability of networked systems for dealing with the network disconnectivity and power consumption, is still under-explored. In this context, we propose a high level model based design of WSNs applications using the UML/MARTE standard to specify network reconfiguration semantics. We define a new package named "NW_Reconfiguration". A case study on water distribution network is proposed to evaluate our proposed design approach.
