A Novel Security Model for Preventing Passive and Active Attacks in WSNs
Wireless sensor networks are widely used for various real time applications due to the technological innovations in this domain. The applications of WSN include monitoring wildlife habitat, military and civilian applications where monitoring is essential without human intervention. These applications need complete security as they are vulnerable to various kinds of attacks. The security and protection of data transmission in WSN are to be performed keeping the resources and life time of network in mind. The lifetime of WSN is less as the nodes are resource constrained.
