Identification of Misbehaving Nodes that Can Drop or Modify the Packets in Wireless Sensor Networks

In wireless sensor networks the common attacks are Packet dropping and modification made by an attacker to disturb communication. Several solutions have been proposed to detect and protect from such attacks, but very few were succeeded. In order to give one effective and efficient solution to this problem, we propose a simple scheme, which can identify misbehaving forwarders or compromised nodes that drop or modify packets and filter the modified pockets. Effectiveness and efficiency of the scheme have been verified by conducting Extensive analysis and simulations
