  • Method and apparatus for dynamic channel access within wireless networks
    Patent number: 7639663
    Abstract: The present invention protocol offers guaranteed Quality of Service (QoS) for a predetermined number of circuits in a highly dynamic, scalable network. The present invention protocol employs a Time Division Multiple Access (TDMA) reservation scheme to transmit deterministic data (e.g., image data) to a destination, while utilizing a Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) contention scheme to support non-deterministic data traffic. The protocol operates over a link-state based routing protocol that reliably floods routing and resource reservation information to the nodes in the network. Moreover, the present invention capitalizes on certain properties of a radio, such as a RAKE type receiver, to enable simultaneous re-transmissions of resource and route reservation information to constructively interfere and enhance the strength and range of the signal.
