Abstract

A communication system (100) dynamically manages a plurality of objects (105). Each object (120) has a communication device (145) placed within or in close proximity to the object (120) for communicating a plurality of object information (245). A group controller (220) communicates with the communication device (145) and takes over responsibility for communication within the communication system (100) for the communication device (145) when the object location (130) comes within a communication range of the group controller (220).
