Methods and apparatus perform location estimation among peer-to-peer devices. For the various methods, data of several different types, such as received signal strength, timing measurements, time stamps, actual transmit power, etc., is measured, stored, and propagated within a peer-to-peer network to enable each device in the peer-to-peer network to calculate positioning coordinates for one or more devices having unknown positioning coordinates.

Methods, computing devices, and systems that dynamically determine whether a service request is authorized or fraudulent are described herein. A computing device may receive a request from a user device, and a geographical location of the user device may be determined based on a signal received from the user device. A determination as to whether to activate the service or not may be made based on the determined geographical location of the user device.

The present application discloses an improved transportation matching system, and corresponding methods and computer-readable media. According to disclosed embodiments, a transportation matching system trains a predictive request model to generate a metric predicted to trigger an increase in transportation provider activity within the geographic area for a given time period. Furthermore, the system determines a predicted gap between expected request activity and expected transportation provider activity for the geographic area during a future time period, utilizes the predictive request model and the predicted gap to generate a metric for the geographic area, and generates an interactive map associated with a customized schedule for the geographic area and the future time period based on the generated metric.
