EFFICIENT TECHNIQUE FOR DETECTING MALICIOUS NODE IN WIRELESS SENSOR NETWORKS

Wireless sensor networks are typically installed in unprotected and harsh environments where security is a significant concern. In such insecure environments, wireless sensor networks are open to many physical and logical attacks. Wireless sensor network security is very important, as these types of networks usually trigger alerts that require sudden attention. There are misdirection attacks which occur due to the presence of malicious nodes within the paths. Due to this there is an increment of delay within the network. This paper focuses on identifying and isolating malicious nodes from the network, the selective forwarding attack within the network.
