Abstract:
This paper proposes a censored and ordered sequential collaborative spectrum sensing scheme for cognitive radio ad hoc network (CRAHN). The scheme uses the ordered of the sensing data reliability for enabling the Dempster Shafer theory of evidence sequential combination. A preceding censored process removes the nodes having insignificant sensing data to the broadcasting sensing result process. The advantage of ordered sequential and censored mechanism will help to reduces communication resources (the energy consumption, the coordination and overhead in control channel and the sensing result collecting time) while keeping the same sensing performance compared with the conventional centralized cooperative spectrum sensing.
