1. A method for establishing communications between a plurality of nodes, comprising:
- determining a set of frequencies used to search for neighbor nodes, said determining further comprising;
providing a key;
generating a list of possible frequencies;
using the key, seeding a hashing function; and
using the hashing function, ordering the list of possible frequencies,wherein each of the plurality of nodes determines the set of frequencies autonomously based at least in part on spectrum awareness data; and
performing an adaptive control channel initialization operation using at least one frequency from the set of frequencies to detect one or more neighbor nodes and when the one or more neighbor nodes are detected, establishing an adaptive control channel with the one or more of the detected neighbor nodes.

Abstract
Establishing communications between a plurality of nodes includes determining a set of frequencies to search for neighbor nodes, and performing an adaptive control channel initialization operation to detect zero or more neighbor nodes. If one or neighbor nodes are detected, an adaptive control channel with one or more of the one or more detected neighbor nodes is established.

11. A wireless node configured to communicate with one or more other wireless nodes, comprising:
-
an interface configured to send and receive signals; and one or more processors, where one or more of the one or more processors are configured to; determine a set of frequencies used to search for a plurality of neighbor nodes, wherein each of the plurality of nodes determines the set of frequencies autonomously based at least in part on spectrum awareness data; provide a key; generate a list of possible frequencies; using the key, seed a hashing function; and using the hashing function, order the list of possible frequencies, and perform an adaptive control channel initialization operation using at least one frequency from the set of frequencies to detect one or more neighbor nodes and when the one or more neighbor nodes are detected, establish an adaptive control channel with the one or more of the detected neighbor nodes. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A system for establishing communications between a plurality of nodes, comprising:
-
means for determining a set of frequencies used to search for neighbor nodes, said means comprising; providing a key; generating a list of possible frequencies; using the key, seeding a hashing function; and using the hashing function, ordering the list of possible frequencies, wherein each of the plurality of nodes determines the set of frequencies autonomously based at least in part on spectrum awareness data; and means for performing an adaptive control channel initialization operation using at least one frequency from the set of frequencies to detect one or more neighbor nodes and when the one or more nodes are detected, establishing an adaptive control channel with the one or more of detected nodes.
