Different types of Sybili attacks and their importance and properties for finding latest mechanism

Abstract

A Mobile Ad hoc Network (MANET) consists of a set of communicating wireless mobile nodes or devices that do not have any form of fixed infrastructure or centralized authority. The security in MANET has become a significant and active topic within the research community. This is because of the high demand in sharing streaming video and audio in various applications .Once MANET is setup it quickly facilitate communications in a hostile environment such as battlefield or emergency situation likes disaster rescue operation. In spite of the several attacks aimed at specific nodes in MANET that have been uncovered, some attacks involving multiple nodes still receive little attention. A reason behind this is because people make use of security mechanisms applicable to wired networks in MANET and overlook the security measures that apply to MANET. Furthermore, it may also have to do with the fact that no survey or taxonomy has been done to clarify the characteristics of different multiple node attacks. This paper addresses the mentioned gap by providing a proper definition and categorization of Sybil attacks in MANET. The whole simulation will take place in MATLAB environment. In the end performance is measured by using the parameters like network load and throughput.
