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.

A network for sensing, communicating and controlling having a plurality of cells which communicate with one another through packets; a first plurality of said cells being coupled to sense conditions and for transmitting packets indicating a change in said conditions, said first plurality of said cells hereinafter referred to as announcer cells; a second plurality of said cells being coupled to control objects in response to predetermined ones of said packets, said second plurality of said cells hereinafter referred to as listener cells; at least one of said announcer cells and listener cells also performing the function of repeating at least some of said packets, hereinafter referred to as repeater cells; a first group of cells being programmed with a first group identification number, said first group including at least one of said announcer cells, one of said listener cells and one of said repeater cells, said cells in said first group being programmed to perform a first group function; a second group to cells being programmed with a second group identification number, said second group including at least one of said announcer cells, one of said listener cells and one of said repeater cells, said cells in said second group being programmed to perform a second group function; said first group of cells communicating among themselves with first packets, said first packets being initiated by at least one of said announcer cells in said first group and acted upon by at least one of said listener cells in said first group; said second group of cells communicating among themselves with second packets, said second packets being initiated by least one of said announcer cells in said second group and acted upon by at least one of said listener cells in said second group; whereby communication occurs among said cells in said first and second group to carry out said first and second group functions.
