Detection of Primary User Emulation Attack in Sensor Networks
Masud Rana, Mazed Rayhan Shuvo · 2018
In this paper, the spectrum sensing problem is solved using the localization defense model with proposed weighted least square algorithm. In this scheme, sensor nodes or secondary users cooperate together to detect and localize the attacker by comparing its location with the position of the primary user. Afterwards, the nonlinear output equations of localisation is linearised using the Taylor series. Finally, the weighted least square algorithm is proposed. The proposed method can effectively compute the optimal weighting factor to minimise the estimation error. Numerical simulation results are demonstrated.
