A Collaborative Approach for Monitoring Nodes Behavior during Spectrum Sensing to Mitigate Multiple Attacks in Cognitive Radio Networks

Algorithm 1

Final decision of spectrum sensing.

Initialization

: All reporting nodes including CH that have

: All reporting nodes including CH that have

: Number of SUs in a cluster

: Threshold value of the reporting node’s belief level

: Threshold value of the number of nodes that should

have the same sensing decision and is equal to

: Votes count of reporting nodes that have SR = 1 and initialized to zero

: Votes count of reporting nodes that have SR = 0 and initialized to zero

: Final sensing decision

: Function to calculate the votes count for each node

: Total votes for all nodes and initialized to zero
