Dynamically Reconfigurable WSN Node Based on ISO/IEC/IEEE 21451 TEDS

Ubiquitous and plug-and-play are fundamental characteristics for the development of wireless sensor networks (WSNs). The ISO/IEC/IEEE 21451 family of standards has recently awakened its interest in this development, making easier the introduction of both characteristics in the design of wireless sensor nodes. Dynamic reconfigurability is also an exciting topic that is gathering interest for the development of embedded systems and smart sensor nodes in the last few years. The use of dynamic reconfiguration increases the scalability and heterogeneity capabilities of the sensor network. However, the ISO/IEC/IEEE 21451 standards do not handle dynamically reconfigurable nodes and previously proposed frameworks do not include this capability into novel wireless sensor nodes. In this paper, an ISO/IEC/IEEE 21451 transducer electronic data sheet (TEDS) architecture for the management of reconfigurable WSNs nodes is proposed. To test the node architecture and validate its capability, the proposed TEDS was implemented for an environmental sensor network.
