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.

Claims

1. 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.

2. The network defined in claim 1 wherein each of said announcer cells and listener cells are associated with one or more groups with each group being identified with a different group identification number, however, where each of said announcer cells announce one of said group identification numbers for only a single one of said groups.

3. The network defined by claim 1 wherein one of said first plurality of cells in an announcer cell in two of said groups.

4. The network defined by claim 1 wherein one of said second plurality of cells is a listener cell in two of said groups.

5. The network defined by claim 1 or 4 wherein each of said cells is fabricated on a single silicon substrate.

6. The network defined by claim 1 wherein each of said cells includes a unique cell identification number and a terminal for enabling broadcasting of said unique cell identification number.

7. A network for sensing, communicating ,and controlling having a plurality of cells which communicate with each other through packets;

a first plurality of said being coupled to sense conditions and for transmitting packets indicating a change in said conditions;

a second plurality of said cells being coupled to control objects in response to predetermined ones of said packets;

said network being organized into a plurality of groups, each of said groups being assigned a unique group identification number, and each of said groups including at least one of said first cells and at least one of said second cells, said cells in each of said groups being programmed to perform group functions, each of said group functions being a common task carried out by said cells in said group, the information needed to carry out said group function being programmed into and distributed among said cells in said group, said packets including on e of said group identification number;

at least one of said cells being programmed to participate in carrying out of at least two of said group functions.

8. The network defined in claim 7 wherein at least on of said packets includes a member number, a different one of said member numbers being assigned to each of said cells in each of said groups.

9. The network defined in claim 8 wherein said packets include a system identification number.

10. The network defined in claim 7 or 9 wherein each of said cells is fabricated on a single semiconductor substrate.

11. The network defined by claim 7 wherein each of said cells includes a unique cell identification number and terminal for enabling broadcasting of said unique cell identification number.
