Abstract: Systems and methods are disclosed for the operation of a network of cognitive radios in a dynamic network topology. The systems and methods make use cross-layer communications to input parameters required by network services into a reasoning engine, which in turns processes the parameter the parameter information and reports linguistic results to the network services. The cross-layer communications are leveraged to shift network service functionality to the MAC or PHY Layers. Route discovery functionality is shifted from routing services down to the MAC or PHY Layers. The route discovery functionality is implemented by a process to elect a relay node based on the number of available channels that each of the source node neighbors has available to communicate with other neighbors.

Abstract: A method of allocation transmission channels of a frequency band to has each of a plurality of remote stations monitor all channels of the frequency band in its area for the presence of transmissions from stations not part of the network. Each remote station transmits its clear channel list to a master station that aggregates the clear channel list into a reservation map, or map of channels that are clear to all stations in the network. The master station then transmits the reservation map to all stations of the network. The individual stations use the channels of the reservation map to transmit information to the master station. Preferably transmission is accomplished using frequency hopping using a set of channels selected from the reservation map.

Abstract: A network of stations uses bandwidth assigned to primary users on a secondary user basis. The stations having a status of needing to send information indicate a need for transmission access by transmitting, simultaneously with transmissions indicating a need for transmission access from other stations of the network, an indication of status to a master station. Each station indicating need for transmission access transmits that indication of status on a respectively different frequency. The master station then grants access to the transmission bandwidth to the requesting stations.
