Abstract

See full text

A network for sensing, communicating and controlling having a plurality of cells which communicate with packets. A packet requesting acknowledgements is transmitted to a plurality of destination cells. The transmitting cell listens for acknowledgements from the destination cells. The transmitting cell waits a predetermined period of time to receive the acknowledgements and then infers that a collision has occurred if a reply is not received from any of the destination cells. Different actions are taken by the transmitting cells as a result of the inference of collision as opposed to a case where the cell receives an acknowledgement from at least one destination cell.
