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.
