Detection and Prevention of the Sybil Attack in Wireless Sensor Networks using Modified RSSI Scheme

Abstract

The nodes in wireless sensor network are not taken care of once deployed to gather information from the hostile environments. This prompts the attackers to steal out the important information by launching various attacks. This paper considers Sybil attack where the attacker impersonates the ID of the genuine node. Earlier the RSSI based scheme has been used to safeguard the WSN against such types of attacks. This paper presents the modified version of the RSSI based scheme which is taken into effect by deploying the high energy sensor nodes. The proposed scheme outperformed the existing scheme in terms of packet delivery ratio and throughput
