DETECTING SYBIL ATTACK BASED ON RSS IN MOBILE AD HOC NETWORKS

Mobile Ad hoc Networks (MANETs) is an autonomous collection of mobile nodes that form a temporary network without any existing network infrastructure or central access point. Since MANETs require a unique, distinct, and persistent identity per node in order for their security protocols to be viable, Sybil attacks pose a serious threat to such networks. Sybil attacker can illegally claim multiple identities on single node and violate one-to-one mapping. There are various approaches to detect Sybil identities on network one of the promising solution is RSS (Received Signal Strength) based detection of Sybil attack this scheme detect Sybil identities without using centralized trusted third party or any extra hardware, such as directional antennae or a geographical positioning system.
