Mitigating the Problem of Packet Dropping & Energy Management in AD-HOC Wireless Network

Abstract

A mobile ad-hoc network (MANET) is a self-arranged network that consists of mobile routers connected by wireless channels. Anonymity communication is a great challenge in MANET. Though there are many anonymity enhancing techniques that have been introduced. These techniques are based on packet encryption to secure the communication anonymity. Still MANET is vulnerable to passive statistical traffic analysis attacks. There are two features of communication anonymity: end-to-end anonymity and source or destination anonymity. This proposed system is designed to discover the communication pattern without decoding the captured packets. First phase of the proposed system is to search the required node. The search is performed by using a heuristic approach. Second phase is to perform statistical traffic analysis. The purpose of this phase is to discover the data transmission of the searched node to its adjoining nodes. After implementing the statistical traffic analysis whether the searched node plays the role of source or destination is estimated. With the help of this estimation the traffic pattern is discovered. The utility of this proposed system is basically in military environment. In order to track the adversaries attack this system is utilized. The adversaries are not able to know that they have been tracked. This proposed system works passively and perform traffic analysis based on statistical characteristic of captured raw packets.
