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.

Abstract
High quality communications among a diverse set of cognitive radio (CR) nodes is permitted while minimizing interference to primary and other secondary users by employing Dynamic Spectrum Access (DSA) in a Dynamic Cellular Cognitive System (DCCS). Diverse device types interoperate, cooperate, and communicate with high spectrum efficiency and do not require infrastructure to form the network. The dynamic cellular cognitive system can expand to a wider geographical distribution via linking to existing infrastructure.

19. A bridge connecting a break in an Internet Protocol network, comprising 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, and where at least one PCN of said first group is in communication with said Internet Protocol network, and each 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. - View Dependent Claims (20)
