1. A dynamic cellular-based cognitive system, comprising:

  • a plurality of cognitive radios each of which is configured to function as a picocell cognitive node (PCN) or a cognitive mobile terminal (CMT) depending on whether said cognitive radio senses the existence of a PCN,where a cognitive radio either establishes itself as a PCN if no PCN is sensed upon sending a registration request or registers itself as a CMT with a particular PCN upon receiving a response to a registration request;

    at least a first group of cognitive radios function as PCNs and at least a second group of cognitive radios function as CMTs,each PCN within said first group provides spectrum management within its respective cell, and each PCN within said first group managing inter-cell communications between one or more PCNs within said first group, andeach CMT with said second group function cognitively, and are configured for both direct intra-cell communications with another CMT or indirect intra-cell communications using the PCN to which it is registered.
