Defense mechanism against stealthy attack in wireless ad hoc network

The local monitoring and a wide variety of overhearing-based attack detection mechanisms cannot detect the stealthy attack. In the stealthy attack, the malicious behavior in an intermediate node disrupts the packet from reaching the destination. The malicious node impresses the nodes that perform local monitoring that it has performed the required routing process.
Stealthy Attacks in Wireless Ad Hoc Networks: Detection and Countermeasure (SADEC) can efficiently detect stealthy packet dropping attack using enhanced local monitoring mechanism. It maintains additional information of each neighbor about the route path, and adds some testing responsibilities to all neighbors. SADEC increases the number of monitoring neighborhoods to improvise the technique of local monitoring.

Solution in NS2

  • Four attacks in stealthy attack can be modeled in ns2.

  • Detection mechanism can be configured with the guard nodes that are common neighbor of successive nodes in the routing path.

  • Detection mechanism reduces the packet loss and increases the packet delivery ratio, throughput.
