Dynamic allocation of spectrum sensing resources in cognitive radio networks

A wireless communication controller comprising:

• a cognitive engine for:
• receiving a first input comprising available spectrum sensing session time for performing spectrum sensing with respect to one or more primary systems;
• receiving a second input comprising a set of communications channels to be monitored in the spectrum sensing session time;
• receiving a third input comprising detection constraints associated with a plurality of available sensing nodes in a secondary network for performing the spectrum sensing;
• and
• receiving a fourth input comprising one or more policy definitions defining interference mitigation parameters for mitigating interference between potential transmissions of the secondary network on a communication channel in the set of communication channels and a wireless device in the one or more primary systems communicating on the communication channel;
• and
• a dynamic resource allocator communicatively coupled to the cognitive engine for:
• dynamically allocating spectrum sensing resources among a set of the plurality of available sensing nodes based on the first, second, third, and fourth input, wherein dynamically allocating spectrum sensing resources comprises at least one of:
• allocating based on a throughput requirement, generating a resource allocation table, calculating cost of spectrum sensing, or selecting available sensing nodes.
