Comparisons of Energy Sources for Autonomous In-car Wireless Tags for Asset Tracking and Parking Applications

In this paper, the viability of MEMS accelerometers is investigated to measure vibration parameters related to different locations of a vehicle with respect to the automotive dynamic functions. The data is collected to compare the accelerometer performances in different locations on the vehicle, including on the hood above the engine, on the hood above the radiator fan, over the exhaust pipe, and on the dashboard. The power spectral density (PSD), together with the time and frequency domain results, confirm the strength and frequencies of the sources of vehicle dynamics. The frequencies obtained from the vibrations of the hood above the engine and radiator fan are approximately 44.18 Hz and 38 Hz, respectively. In terms of the vibration amplitude, the measured amplitudes are between 0.5 g and 2.5 g in both cases. Furthermore, the time domain data collected on the dashboard during driving mode reflects the road condition. Overall, the knowledge obtained from the various tests conducted in this paper can be advantageous for further control and development of vehicle diagnostics, safety, and comfort.

Nowadays, the crowded of cars leads to big challenges in many crowded cities. This leads to environmental pollution in addition to fuel consuming. In addition, it is very important to adapt all devices, vehicles, and objects to the environment of the internet of things (IoT). In this case, it is difficult to find the nearest and shortest suitable path for car parking place. This approach aims to minimize the time for finding the car parking as well as reducing the traffic congestion. The implemented approaches try to support the driver to find near suitable car parking. The implemented approach based on intelligent aspects to achieve the performance of car parking with the future environment of IoT. Localizing of the nearest car parking is an important issue in the future IoT.
