The integration of security mechanisms is facilitated by collaboration-oriented models of the functional system specification (i.e., by d...

In last few decades, there has been a wide demand of wireless sensor networks (WSNs) in extensive mission critical applications such as monitoring, industrial control, military, health and many more. The larger demand of WSN in mission critical applications makes it more prone towards malicious users who are trying to invade. These security assaults worsen the performance of WSN in large extent...
