Abstract :

MANETs require a unique discrete and persistent identity per node in order for their security protocols to be viable, Sybil attacks pose a serious threat to such networks. A Sybil attacker can either create more than one identity on a single physical device in order to launch a synchronized attack on the network or can switch identities in order to weaken the detection process, thereby promoting lack of responsibility in the network. In this research, we propose a lightweight scheme to detect the new identities of Sybil attackers without using centralized trusted third party or any additional hardware, such as directional antennae or a geographical positioning system. Through the help of wide simulations and real-world test bed experiments, we are able to demonstrate that our proposed scheme detects Sybil identities with good precision even in the presence of mobility.
