Abstract
A method includes monitoring, by a receiver of a first node, a portion of a spectrum. The method also includes receiving, by the receiver of the first node, a signal on a first frequency within a range of frequencies. The method additionally includes determining that the received signal is a link request from another node. The method further includes decoding a proposed link configuration from the link request. The proposed link configuration includes a proposed transaction frequency for a transaction to be sent to the first node from the other node. The proposed transaction frequency may be the same as or different from the first frequency. The method may also include determining, by a processor of the first node, whether the proposed link configuration is suitable. The method may additionally include receiving, by the receiver, at least one signal indicative of the transaction from the other node.
