Anomaly detection of the NAV attack in MAC layer under non-time and time-constrained environment

This paper proposes and investigates an anomaly detection of the NAV attack under time-constrained and non-time constrained environment in MAC layer. Time-constrained environment refers to the condition in which the attack is for a particular time interval in the transmission while for the non-time constrained environment it is for the whole transmission period. We present simulation and analytical results showing that the NAV attack can under perform the standard 802.11 MAC protocol. Further no approach has been explicitly specified to detect this attack. This is a simple method to detect the NAV attack using Glomosim
