Location privacy is an ever increasing concern as the pervasiveness of computing becomes more ubiquitous. This is especially apparent at the intersection of privacy, convenience, and quality of service in cellular networks. In this paper, we show the long term evolution (LTE) signaling plane to be vulnerable to location-based attacks via the timing advance (TA) parameter. To this end, we adapt the...
Wireless geo location is an increasingly relevant area of research as cellular technology becomes ever more ubiquitous. In this work we consider the timing advance parameter in Long Term Evolution cellular networks to this end. We also evaluate a previously introduced method of position estimation augmentation called Cellular Synchronization Assisted Refinement (CeSAR). We first develop the concept...
The vulnerability of cellular networks to location-based attacks via uplink timing management commands has been studied since the advent of GSM. However, the introduction of heterogenous networks as the answer to increasing demand for data throughput has resulted in a new vulnerability to such attacks. In this work, we propose Cellular Synchronization Assisted Refinement (CeSAR), an entirely passive...
Inferring user equipment (UE) location in cellular networks via uplink timing management presents attractive possibilities in an increasingly mobile-connected world. Power constrained mobile devices with ever more common applications that rely on location-based services demand an alternate solution to positioning than a Global Navigation Satellite System (GNSS) and its derivatives. In this paper we...
The maritime domain is important to the security, prosperity and vital interests of the global community. In order to protect these interests, governments require capabilities that provide situational awareness of the maritime domain. In [11] a spatiotemporal analysis approach is proposed that autonomously analyzes and classifies ship movement and possible intent at sea. The analysis focuses on detection...
Traditional approaches to pattern based positioning have proposed schemes specifically tailored for the area of interest in which they are employed. Many, when applied to a generic search environment, may not scale computationally due to either a very large tracking area, very fine granularity in the database, or both. Here, a novel framework for fingerprinting that utilizes a k-generation structure...
Recent advancements in low power micro sensors and wireless network technology have enabled a host of new sensor network applications. One such application is collaborative geolocation using time difference of arrival measurements from a wireless sensor network consisting of mobile ground or airborne sensor nodes. This paper introduces a two-stage geolocation scheme that begins in an optimal bearing...
