ABSTRACT:
A network architecture that coordinates shared access to a wireless transmission medium while avoiding collisions between simultaneous transmissions even where network nodes cannot hear one another. There is also the capability of readily reconfiguring a wireless network to accommodate new nodes. In one embodiment, there is a hierarchy of master nodes that coordinate wireless transmissions by the other nodes. Since the need for retransmission is minimized, throughput is improved.
