Collusion attack in Optimised Link State Routing requires malicious node to be the only multipoint relay (MPR) node of the victim. After its initiation, the attack converges in [TC interval, Topology Holding Time]. A node having only one MPR sends scruple packets to its neighbourhood. Absence or limited presence of acknowledgement of scruple by three-hop neighbours indicates attack. Countermeasure is affected through forcing at least two nodes in MPR set of every node.
