Data fusion on wireless sensor and actuator networks powered by the ZenSens system

Abstract

Wireless sensor and actuator networks (WSANs) provide sensor and actuator services through small smart nodes with very limited hardware and power supply. Information fusion must be considered a critical step in WSAN design, enabling energy saving, increasing data quality and deeper insight of the monitored environment. This study presents experimental results over real hardware on inner-node fusion in the context of the ZensSens system. ZenSens provides user-centric WSAN functionality, with IPv6 support at the sensor node level, automatic node attachment and suitable software tools for multi-channel access. This study presents some material about information fusion, the ZenSens system and possible solutions for inner-node information fusion based on real temperature sensor data. The approach proves the feasibility of inner-node fusion on constrained hardware with IPv6 support.
