A Wireless Sensor Network (WSN) is also considered as an adhoc network in which nodes are extended with sensing capability. The nodes of WSN are randomly deployed in harsh environment for detecting and tracking the passage of troops and tanks on a battlefield and measuring the traffic flows on roads. So, the sensing nodes are prone to different types of routing attacks. The various routing attacks are spoofed routing information attack, HELLO flood attack, sybil attack, selective forwarding attack, sinkhole/black hole attack and worm hole attack. These attacks disrupt the routing mechanism of...
