Detecting and Mitigating Smart Insider Jamming Attacks in MANETs Using Reputation-Based Coalition Game

Algorithm 3

Jammer exclusion from the coalition.

(1) Node checks node ’ reputation value after update.

(2) Node is tolerated until its reputation falls below

(3) Classify misbehaving nodes according to:

(4)  if   is below   then

(5)  Node sends an alarm message

(6)  All nodes change their channel of transmission

(7)  Accused node’s payoff reduces due to bad testimony

(8)  Node attempts to jam the communication channel that has the best transmission rate.

(9)  Jammer records little or no success because of the proactive step taken by the coalition.

(10)  Neighbors of node , blacklist him and exclude him from their small coalition.

(11)  Nodes with reputation greater than regroup again.

(12) else

(13)  No alarm is sent and nodes continue their transmission

(14) end if

(15) Nodes with greater than are retained

(16) Continue transmission
