An ultrasound tracking system is an inexpensive and accurate technique for indoor object tracking. In this paper, we describe an IEEE 802.15.4-based active tracking system that tracks multiple mobile objects effectively. We analyze the problems of the active tracking system with multiple objects and propose an adaptive beaconing algorithm as the solution. In our algorithm, mobile nodes overhear the beacon messages of other mobile nodes and adaptively adjust their beaconing periods to avoid a simultaneous ultrasound pulse. We implemented the tracking system in a real environment and measured the performance of the system. The experimental results show that our algorithm successfully works with multiple mobile nodes and improves performance on the success rate.

The paper contributes to the design and implementation of the ultrasonic positioning system based on new multifunctional hardware components, newly released. A moving object coordinates’ determination is described analytically and a matrix equation in respect to unknown coordinates with coefficients, measurement distances, is derived. Stages of data packet processing are formulated, and a pseudo pyramid of measurement distances is built. HX7TR multifunctional ultrasonic devises, transceivers, are used to implement the positioning system. A C# program source code for coordinate determination and 3D visualization is created. The algorithm for moving object coordinate computation, and its program realization as well as HX7TR ultrasonic devises can be used in development of indoor ultrasonic positioning systems embedded in IoT and robotics applications.
