Automatic Construction of Cognitive Radio Network

This paper presents a scheme for cognitive radio network construction. Incorporating the available spectrum, cognitive radio nodes automatically construct a local area network. The active cognitive radio nodes in an area form groups. Each group consists of a leader node, inter-group nodes and regular nodes. Inter-group nodes connect different groups to construct a network. Furthermore, the group leaders of different groups form virtual groups to facilitate the network management. The proposed scheme can also be used to construct large scale cognitive radio networks. Its applications include temporal network deployment in emergency situations and home appliance network construction.
