A network for sensing, controlling and communicating information. The network comprises a plurality of cells including a first cell for sending a packet of information, a second cell for receiving the packet of information and a plurality of repeater cells for repeating the packet prior to its arrival at the second cell. A method is described including the steps of generating a random number and including the random number in the packet; performing a calculation by the repeater cells of fields including the random number to generate a first number; storing the first number; performing a calculation on subsequent packets received by the repeater cells to provide a second number; comparing the second number to the first number; and rebroadcasting the subsequently received packet if the second number is different than the first number.
