Every common man has a smartphone and carries it everywhere. When people travel to any new place, in order to locate and find path to their destination, they use GPS in their smart phones. But GPS is not precise for small scale and does not work inside the buildings; therefore the need of indoor positioning arises. Our motivation behind the project is to come up with indoor navigation application that can help any new visitor to locate and find path to their destination easily inside the campus. Indoor navigation application uses BLE beacon. BLE beacon allows mobile application to determine their location on a micro- local scale. Beacon and smartphone use Bluetooth Low Energy technology for communication. Since it uses Bluetooth Low Energy for communication it consume very less battery power. Keywords: iBeacon, BLE, Smartphone, Android Application. I. INTRODUCTION In today's world technology has much influence on mankind. Human life is dependent on technology. People carry their smart phone wherever they go. Today, mobile phones are not just used for making calls and messaging but for many other purposes.

  • Mobility Improves the Security of Location Awareness in Wireless Networks
    Dissertation Mobility Improves the Security of Location Awareness in Wireless Networks Thesis approved by the Department of Computer Science of the University of Kaiserslautern (TU Kaiserslautern) for the award of the Doctoral Degree Doctor of Engineering (Dr.-Ing.) to Matthias Schäfer Date of Defense: June 29, 2018 Dean: Prof. Dr. Klaus Schneider PhD Committee Chair: Prof. Dr. Heike Leitte Reviewers: Prof. Dr. Jens B. Schmitt Prof. Dr. Christina Pöpper Dr. Vincent Lenders D 386 Abstract Mobility has become an integral feature of many wireless networks. Along with this mobility comes the need for location awareness. A prime example for this development are today’s and future transportation systems. They increasingly rely on wireless com- munications to exchange location and velocity information for a multitude of functions and applications. At the same time, the technological progress facilitates the widespread availability of sophisticated radio technology such as software-defined radios. The result is a variety of new attack vectors threatening the integrity of location information in mobile networks. Although such attacks can have severe consequences in safety-critical environments such as transportation, the combination of mobility and integrity of spatial information has not received much attention in security research in the past. In this thesis we aim to fill this gap by providing adequate methods to protect the integrity of location and velocity information in the presence of mobility. Based on physical effects of mobility on wireless communications, we develop new methods to securely verify locations, sequences of locations, and velocity information provided by untrusted nodes. The results of our analyses show that mobility can in fact be exploited to provide robust security at low cost.

But, along with the development of smartphone technology, the visually impaired people began using smartphones to help them engage in any activities. Estimote beacons are a small device that broadcast a Bluetooth signal that can be captured by a smartphone. This research contributions to provide the information to the visually impaired person in order to have easy use compatible with the smartphone since the Estimote beacons are used as a location awareness device to give the information about the surrounding environment. The systems were configured and programmed using android studio for indoor and outdoor locations. Based on the indoor result testing, it can be stated that the implementation of the Estimote beacon as a location awareness in indoor area, must be focused on the installation of the Estimote beacons. The installation must be set smoothly and the broadcast signal should not be overlap. The outdoor result testing indicates that the Estimote beacon signal is stable to receive on the smartphone at a distance 0 – 31.64 meters, begin unstable at a distance of 38.61 meter and become undetected at a distance of 79.79 meters.
