1. A method for dynamic spectrum allocation to a secondary communication system seeking to operate within the spectrum of a regulated primary communication system, the method comprising:

  • clustering a plurality of secondary devices based on an operating frequency utilized by each of the secondary devices;

    receiving sensing information from each of the clustered secondary devices, wherein the sensing information indicates at least one of an occupied channel frequency and an unoccupied channel frequency in the spectrum;

    determining at least one spectrum opportunity, in the spectrum, that is unoccupied by each of a plurality of primary devices based on the received sensing information; and

    allocating the at least one spectrum opportunity to at least one of the plurality of secondary devices.
