Abstract
The present invention relates to a system and method for providing power management to sensing nodes in a sensor network. A system may include a plurality of sensing nodes, each sensing node connected through a power management device to an external power source, such as a powered node of another network, for managing power from the external power source to the sensing node. Beneficially, a plurality of power management devices allow for a sensor network of fixed or mobile wireless sensing nodes or sensor gateways to make use of power from an external source such as an another network e.g. an existing emergency lighting system or other similar powered building system. Thus for example, a sensor or group of sensing nodes and their associated power management devices may be integral with or co-located in proximity to powered nodes of these other networks. An intelligent power management device connected to at least one of the sensing nodes may provide for power policy management to sensing nodes based on monitoring power conditions such as available power, power level status, and information obtained from the sensing nodes indicative of network conditions, detecting a change therein, and regulating power to the sensing node depending on the change.
