Analysis Of Sybil Attack Detection In Mobile Adhoc Network

Mobile ad hoc networks (MANET) is a very complicated distributed systems that comprise of mobile nodes in wireless network that can easily and freely arrange themselves into random and momentary ad hoc network topologies as per the situation in network. The changing topology and resource restriction are the main characteristics which pose a number of tasks for efficient and lightweight security protocols design. Centralized identity management is not present in case of MANETs. The requirements of a unique, distinct, and permanent identity each node are primary requirements for their security protocols, due to this Sybil attacks create a harmful threat to such networks. Many or single identity in ad hoc network, can be created by a Sybil attacker in order to release coordinated attack on the network or can change identities in order to make it weak for the detection process, thereby alter it in lack of accountability in the network. This is the research which will be implemented to detect the identities created by attackers illegitimate node with a lightweight scheme without using any extra hardware, like directional antennae or a geographical positioning system.
