Decoy Black-Hole Attack
Sabeeha Mehtab, Aruna B. Dulloo · 2012
Mobile ad hoc networks are being widely deployed currently since they provide some features, which are difficult or impossibl e to be achieved by conventional networks. The application area ranges from the battlefield (sensor nodes in hostile territory) to general transportation that provide useful infrastructure during disaster recovery. Due to the great importance of MANET, security in ad hoc networks is a hot research area and already significant research is done in this field. The use of wireless links in an ad hoc network generates the possibility of link attacks from passive eavesdropping to active impersonation, message replay and message distortion. The Black hole attack is an active insider attack, where a malicious node uses the routing protocol to advertise as having the shortest path to nodes whose packets it wants to intercept. Wide research has been done in this area that motivated us to take this as challenge to integrate a better security solution into the existing AODV routing protocol.We have proposed a DAODV (Decoy Black-Hole AODV) algorithm uses a virtual and nonexistent address as a sender node to misguide and identify Black-Hole nodes. This algorithm works in proactive as well as reactive manner of defense architecture in MANET. Index Terms—AODV, BlackHole,MANET,RERR, RREP, RREQ, RREQ'. ————————————————————
