A Modified Method for Preventing Blackhole Attack in MANETS

Black hole attack is one of the security threat in which the traffic is redirected to such a node that actually does not exist in the network. It's a real world analogy to the black hole in the universe in which things disappear. The node presents itself in such a way to the node that it can attack other nodes and networks knowing that it has the shortest path. MANETs must have a secure way for transmission and communication which is quite challenging and vital issue. Study of previous work concludes that works done on security issues in MANET were based on different reactive routing protocol but still there is needs to avoid Black Hole attack in MANETs. This research work proposed detection and mitigation technique to avoid black hole attack and improve the network performance. Performance of proposed solution is similar with original AODV and tries to maintain privacy of content.
