Fig. 3. NS-2 showing the Abnormality and actions taken against certain nodes

The simulation scenario is maintained as in [10] for BIOSARP and SAID
comparison. When network has suffered attack by 10 malicious nodes, the power
consumption value increased. Once the AIS self-security measure starts functioning,
the energy consummation starts to reduce. And as soon as the malicious nodes stop
attacking, the power consumption comes to the normal situation as observe at 450th
sec in Figure 4.

Figure 5 shows the performance of BIOSARP as the number of compromised node
increases from 4 to 20. In Figure 5, the power consumption increases as the number of
