Abstract

Fully self-organized mobile ad hoc networks (MANETs) represent complex distributed systems that may also be part of a huge complex system, such as a complex system-of-systems used for crisis management operations.In this project, we will present our scheme that detects Sybil identities. In particular, our scheme utilizes the RSS in order to differentiate between the legitimate and Sybil identities. The proposed scheme can be applied to both scenarios of Sybil attacks, i.e., whether the new identities are created one after the other or simultaneously created. Our detection scheme can work as a standalone scheme, but could equally be deployed as an add-on to existing schemes, for example it could be incorporated into a reputation-based system, i.e., the detected Sybil identities from the MAC layer will be plugged into the reputation based system on network layer. Our proposed scheme does not use localization technique for Sybil attack detection and hence does not need any directional antennae or any GPS equipment.
