Abstract: Various systems and methods for Internet of Things (IoT) network sensor fusion are provided herein. A system for providing sensor collaboration includes: a sensor command circuit to access first-tier sensor data from a first-tier sensor associated with a user; a risk assessment circuit to use the first-tier sensor data to determine a risk rating, the risk rating representing a potential risk to the user; a user context circuit to determine a user context from the first-tier sensor data, wherein the user context circuit and the sensor command circuit are to selectively access second-tier sensor data from a second-tier sensor based on the user context; and a rule evaluation circuit to access a rule database to identify a rule corresponding to the risk rating and user context, and execute the rule when the rule is identified.
