Abstract
Systems and methods for generating sensor tag locations expressed in a three-dimension global coordinate system from sensor tag locations expressed in three-dimensional local coordinate systems of mobile readers that read each tag and for updating the paths of each mobile reader are disclosed. In one embodiment, a method includes receiving sensor data from one or more mobile reader agents, receiving tag location data that describes the location of one or more sensor tags expressed in local coordinates of the subspace of the mobile reader agent that read the sensor tag, converting the tag location data into a global coordinate system that is common to all mobile reader agents, and updating one or more paths of one or more mobile reader agents to increase the coverage of reading tags in the subspace of the mobile reader agent.
