ON THE PERTURBATION OF LOCALIZATION NETWORKS USING RECEIVED SIGNAL STRENGTH

This paper considers the problem of source localization under received signal strength in the presence of an intelligent adversary. The adversary's goal is to redirect the location estimate to a specified location away from its true value by slightly perturbing each of the sensors' position measurements. This work takes the viewpoint of the adversary and determines the false positioning information to be injected using a semidefinite programming approach. Varying levels of control are considered where a penalty is imposed for corrupting certain sensors in the network. It is shown that the adversary can successfully achieve the desired redirection of the network's location estimate.
