Abstract

Location service, which provides current geographic positions of nodes, is one of the key elements of position-based routing schemes for ad hoc networks. In this paper, we define security threats of location service and propose a new secure location service protocol that uses self-signed locations. In our proposed protocol, nodes register their public keys in other nodes during the initialization phase and these registered keys are used to verify the locations of other nodes and to generate their self-signed locations. In this paper, we show that our protocol is robust against traditional attacks and new attacks that may occur in position-based routings. We also analyze the efficiency of our protocol using various simulations.
