SABAD: SELF ASSURED BLACK-HOLE ATTACK DETECTION ON AODV PROTOCOL IN MANET

Designing of a secure routing protocol is a challenging issue in mobile ad-hoc network (MANET) because of the lack of trusted centralized authority, easy eavesdropping, dynamic network topology and limited resources. The false alarm raised during malicious node detection prevents the genuine nodes, from their normal activities. If an adversary could succeed on generating false alarm and therefore isolates a number of nodes from the network which leads to a DoS attack. This paper proposes a defense mechanism called SABAD, against black-hole attacks on AODV protocol in MANET. SABAD considers all the major factors contributing for packet dropping to reduce false-alarm during black-hole node detection.
