Abstract
Abstract A network for sensing, communicating and controlling employing a plurality of cells which communicate through packets. First cells are assigned an announcer function, others a listener function with at least one announcer or listener cell also performing the function of repeating at least some of the packets. The cells are organized into groups, each group being assigned a group function. Group identification numbers are included in the packets to allow the cells for a particular group to identify packets intended for it.
