ISO/IEC/IEEE 21451 Compliant Sensor Nodes for Energy-Aware Wireless Sensor Networks

Much attention is focused nowadays on the developing of energy-aware wireless sensor and actuator network (WSAN) and in particular on implementing network control algorithms by exploiting the ability of a sensor to reliably estimate and report its energy status at network level where energy-saving strategies can be implemented. This poses the attention on how a sensor may transfer information regarding its energy resources at network level in a standardized way. In this paper, we face the problem concerning the realization of energy-aware WSAN by using ISO/IEC/IEEE 21451 compliant sensor nodes. To this end, some guidelines on how exploiting the capability of the current version of the ISO/IEC/IEEE 21451 standard to obtain information about the energy-status of network nodes will be reported and, furthermore, some extensions for overcoming the existing shortcomings will finally be proposed.
