Since its introduction to the public in 1994, the Global Positioning System (GPS) has been used in every aspect of our lives. While GPS works just fine most of the times, such as navigating an unknown city using a portable GPS unit or soldiers using it in the battle field, scenarios arise where GPS fails as a reliable positioning and localization system; like inside buildings and tunnels. Cooperative localization using cellular phones would solve this problem since there is a much higher number of information sources (other surrounding cellular users) that are much closer to the user, whereas the GPS system only has a limited number of information sources which are thousands of kilometers away. Spoofing, although not popular in GPS, is a topic of a few research papers. With the introduction of cooperative localization, spoofing will be easier to implement and harder to defend against. Not much research has been done to study the effects of spoofing attacks on cooperative localization networks. In this dissertation, it is shown that reliable positioning and localization is possible using cooperative localization through cellular networks. In addition, it proves that processing sufficient information from a number of information transmitting users can mitigate spoofing attacks on any network. This can be done by filtering out the extreme location estimations resulting from the spoofing attacks. Since Kalman filter helps in predicting the movement of mobile users, using Kalman filter for mobile network users significantly helped reduce the error in estimating the user’s location.

Location-aware technologies have the potential to revolutionize computing, cellular services, sensor networks, and many other commercial, military, and social applications. In wireless networks, accurate information about an agent's location can give meaning to observed data and facilitate the agent's interactions with its surroundings and neighbors. Determining the location of one or more agents, known as localization or positioning, is a fundamental challenge. Most existing localization methods rely on existing infrastructure and hence lack the flexibility and robustness necessary for large ad-hoc networks. In this thesis, we describe a framework for localization that overcomes these limitations by utilizing cooperation: the agents in the network work together to determine their individual locations. We derive a practical algorithm for cooperative localization by formulating the problem as a factor graph and applying the sum-product algorithm. Each agent uses relative positioning measurements and probabilistic location information from its neighbors to iteratively update its location estimate. We investigate the performance of this algorithm in a network of ultra-wideband (UWB) nodes, which are well-suited for localization due to their potential to measure inter-node distances with high accuracy. Realistic models of UWB ranging error, based on an extensive measurement campaign in several indoor environments, are incorporated into the localization algorithm. Using the experimental data and simulations, we quantify the benefits that cooperation brings to localization.

Modern day networking and computing systems rely increasingly on knowing the location of the user. These include state-of-the art technologies such as navigation of vehicles and robots, traffic planning, or light control in smart home environments. In the future, even more services will appear. The predominant localization technology currently uses satellite signals but this only works outdoors, is expensive, and consumes considerable power. Alternative localization technologies have been recently developed using optical, ultra-sound, or radar techniques. All of these require additional hardware components to work effectively. Radio-frequency (RF) localization is a technique that uses communication signals to perform the task without the need for any extra hardware. This monograph addresses the role of synchronization in radio localization and provides a comprehensive overview of recent developments suitable for current and future practical implementations. The material is intended for both theoreticians and practitioners and is written to be accessible to novices while covering state-of-the-art topics of interest to advanced researchers of localization and synchronization systems.
