In Sybil attack, attackers use several identities at a time or they take-off identity of some trustworthy node present in the network. This attack can create lots of misinterpretation in the network like decrease the trust of legitimate node by using their identities, disturbs the routing of packets so that they cannot reach to its desired destination, and many more. Like this it disturb the communication among the nodes present in the network. Sybil attack is very much destructive for mobile ad-hoc network. In this research, we implemented the Lightweight Sybil Attack Detection technique which is used to detect the Sybil nodes in the network and also discussed the proposed work with implementation which is used to improve the existing Lightweight technique. Simulation tool used for the implementation is MATLAB.
