Mitigation of Sybil Attack on A Campus Network (CANET) Using Inter-Arrival Time Threshold and Physical Address Comparison

Abstract

A particularly detrimental attack ravaging campus and ad hoc networks is the Sybil attack, where a node illegally claims more than one identity, targeting honest and genuine nodes, thereby weaken or disrupting the system. This research work aimed at designing a mitigation mechanism to combat the attack on a Campus network (CANET). Setting threshold and checking for IP address spoofing by comparing nodes physical addresses is the focus of this work. The success of the algorithm is validated by simulation, and quality of service is guaranteed with regards to the detection rate and packet delivery ratio.
