Testing and reconfiguring the application based modulation suited for cognitive radio

Reconfiguration plays a vital role in resource utilization. The functional, interconnect testing of digital circuits is done using Boundary Scan Trainer (BST) kit. The faulty cores if replaced by spare ones in real time reduce the switching time. This procedure is implemented in wireless network system also. The proposed work focuses on wireless communication among nodes, grouping them as different clusters so as to form a virtual logic channel for each cluster, implemented using kernel customized, low power consuming hardware modules. A large number of simple low-power nodes are distributed in the field and transmit data in a secured manner.
