Detection of Misbehaving Nodes Due to Outsider Attack in Wireless Sensor Network

Abstract: Wireless Sensor Networks (WSNs) are engaging technology for monitoring large regions at high spatial and temporal resolution. Hence the security of these sensor nodes must have the most top priority. The wireless sensor network can carry some secret information to the sink node in some sensitive applications. Packet dropping and modifying are the two most common attacks on wireless sensor networks. Till now, various algorithms are proposed to identify packet dropping, but no algorithm is proposed to catch those packet droppers and modifiers, which may again cause packet dropping and modifying. In this paper, we recommend a simple yet powerful scheme to catch packet droppers and modifiers. Keywords: Packet dropping, packet modification, intrusion detection, wireless sensor networks
