A Survey on Traffic Pattern Discovery in Mobile Ad hoc Network

Abstract

-Mobile Ad-hoc Network (MANET) is type of unguided network whose nodes are self-configuring and connected by wireless links. Anonymity communication is one of the major issues in MANET. Many anonymity enhancing techniques have been introduced based on packet encryption. These were designed for the protection of communication anonymity in mobile ad hoc networks. However, passive statistical traffic analysis attacks that can be vulnerable to MANET. The communication anonymity consists of two aspects: source/destination anonymity and end-to-end anonymity. In order to discover the communication pattern without decrypting the captured packets, this proposed system will be designed. The proposed system will first search the required node by using a heuristic approach. Then statistical traffic analysis will be performed to find the data transmission of the searched node to its neighboring nodes. After performing the statistical traffic analysis, the probability of the searched node being a source or destination will be determined.
