A Revised Approach on Attack Identification and Handling in WSN
Abstract: Security is one of the most critical vectors for any network. When the network is an open adhoc network; this criticality also increases. Sensor network is one of such network that suffers from different kind of internal and external attacks. The internal attacks are more crucial for the network because it is done by the authenticated member nodes. These attacks affect the network by affecting the QoS parameters over the network. In this present; a layered architecture is presented to handle the internal attack in wireless sensor network and to provide the effective throughput over the network. The presented work is divided in three stages. In first stage; the network nodes are analyzed under the throughput; delay and energy consumption parameters. Based on this analysis; the first level critical nodes are identified. Now before deciding the nodes as the attacker nodes; these nodes are required to keep in observation. At the second stage; to observe the nodes; the effective monitoring node selection is defined in this work. To monitor each attacker nodes m observer nodes are identified under the coverage range and energy parameters. The analysis on these nodes is performed under different parameters such as PDR; energy loss; communication delay etc. Now at the third stage; the Dempster-Shafer theory will be applied on these parameteric evidence under different beliefs. Based on these belief oriented observation; the identification of the attacker node will be done. .
