A reconfigurable WSN node based on ISO/IEC/IEEE 21451 standard

Ubiquitous and plug-and-play are fundamental characteristics in the development of Wireless Sensor Networks (WSNs). The ISO/IEC/IEEE 21451 standard has proven its interest in this development, making easier the introduction of both characteristics in the design of wireless sensor nodes. Re-configurability is a new subject that is gaining importance in the development of embedded systems and wireless sensor nodes in the last few years. Sensors re-configurability capability increases the scalability and heterogeneity abilities of sensor nodes. However, previous developed frameworks and standards do not support the implementation of these capabilities into novel wireless sensor nodes. This paper presents an ISO/IEC/IEEE 21451 based node architecture for WSN nodes that support the management of reconfigurable devices. The node is implemented in an Environmental Sensor Network to validate its interest and utility. Keywords—WSN, ISO/IEC/IEEE 21451, Re-configurability, PSoC.
