Efficient Dynamic Data Flow and Black Hole Detection in Manet
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 7
Abstract
In Wireless networks, when data packets are being transferred between nodes from a specified node to destination, then source node checks for shortest path to reach destination. In this approach there may be a possibility of occurring attack called BLACKHOLE attack. In Black Hole attack, source node sends Route Request (RREQ) to its neighbor nodes to know which node contains shortest path to reach destination. So malicious node sends Route Reply (RREP) to source node that it has a valid route to destination and then responds with False Route Reply (RREP). Then Source node transmits data to the destination through this malicious node. Then the malicious node absorbs or drops the data packets that are destined for destination. In this, an approach is proposed to detect the malicious node along with Routing tables. It can also show the metric analysis like packets sent, packets Received, Dropped Packets etc. A Runtime frame work for dynamic data flow using Network Simulator2 (ns2) has been proposed to implement black hole attack.
