While a growing number of Internet of Things (IoT) applications require reliable mechanisms to determine the precise location of remote devices, the aspects regarding the security of positioning algorithms should not be neglected. In this context, this paper proposes a physical-layer location verification method for IoT networks in which the concentrator node is assisted by several anchor nodes that are spread in the area of interest. We design an optimization problem to choose appropriately which anchor nodes should be triggered in the location verification process in order to minimize the activation rate of each anchor.

Abstract

While a growing number of Internet of Things (IoT) applications require reliable mechanisms to determine the precise location of remote devices, the aspects regarding the security of positioning algorithms should not be neglected. In this context, this paper proposes a physical-layer location verification method for IoT networks in which the concentrator node is assisted by several anchor nodes that are spread in the area of interest. We design an optimization problem to choose appropriately which anchor nodes should be triggered in the location verification process in order to minimize the activation rate of each anchor. The performance evaluation results show that the proposed policy achieves an activation rate reduction of the anchor nodes of at least 70%.
