Create a friend finder application for smartphones! The application allows the user to choose a friend from his friend-list, for which to get notified as soon as he is in his vicinity. The application is entitled to use the smartphone’s positioning methods (e.g., GPS, Cell-ID, WiFi) to track users in the background. Subscribing for friend finder scenarios is performed via the Positioning Enabler Platform.


  • Analyze state of the art technologies and algorithms from research
  • Implement API required by the user to subscribe for friend finder
  • Implement user authentication and authorization
  • Implement server vicinity reasoning algorithm
  • Implement user notification method


  • Android Development
  • Java Application Server (J2EE)
