Abstract
An apparatus, method and computer readable device for providing spatial information in a sensor network. The sensor network comprises a plurality of sensors and a plurality of actuators, each sensors and actuators have a unique id and a known spatial location within a spatially-bounded zone and a database is provided for storing the location each sensor and actuator. A spatial-processor generates a plurality of context zones based upon the information contained in the location database to provide actuator coverage for the spatially-bounded zone. Each context zone is generated by assigning a subset of the plurality of sensors as a spatial boundary of each context zone and by deploying a subset of the plurality of actuators into one or more context zones. In operation, the spatial-processor determines if an actuator has failed in context zone and redeploys one or more actuators from another intersecting context zone to the context zone containing the non-operational actuator.
