Design of Traffic Pattern Discovery System in Mobile Ad Hoc Network

Mobile Ad-hoc Network (MANET) is a collection of loosely connected nodes through wireless links. The mobile nature and dynamic route formation of the network exposes it to variety of attacks. MANET finds its application in wide range of domains which includes military environment where confidentiality and detecting the activities of groups indulged in war crimes. This includes detecting the identity of anonymous nodes in the network. Traffic analysis type of passive attack on MANET aims to discover the identity of such anonymous nodes. Traffic Analysis attack monitors the packets communicated between the nodes and works fine if every packets are encrypted. The proposed system targets to disclose the identity of anonymous nodes in a MANET where Best-First Search is employed for route formation. The proposed work will find out the possibilities of a node being a sender or receiver for the analyzed traffic. The results can be obtained in matrix form where each row will refer to each node. The work completed up till now includes analysis of the traffic in static manner and finding out the source and destination of the packets transmitted. Network Simulator-2 (NS2) is used for simulating the results.
