  A dataset, collected under an industrial setting, often contains a
significant portion of noises. In many cases, using trivial filters is not
enough to retrieve useful information i.e., accurate value without the noise.
One such data is time-series sensor readings collected from moving vehicles
containing fuel information. Due to the noisy dynamics and mobile environment,
the sensor readings can be very noisy. Denoising such a dataset is a
prerequisite for any useful application and security issues. Security is a
primitive concern in present vehicular schemes. The server side for retrieving
the fuel information can be easily hacked. Providing the accurate and noise
free fuel information via vehicular networks become crutial. Therefore, it has
led us to develop a system that can remove noise and keep the original value.
The system is also helpful for vehicle industry, fuel station, and power-plant
station that require fuel. In this work, we have only considered the value of
fuel level, and we have come up with a unique solution to filter out the noise
of high magnitudes using several algorithms such as interpolation,
extrapolation, spectral clustering, agglomerative clustering, wavelet analysis,
and median filtering. We have also employed peak detection and peak validation
algorithms to detect fuel refill and consumption in charge-discharge cycles. We
have used the R-squared metric to evaluate our model, and it is 98 percent In
most cases, the difference between detected value and real value remains within
the range of 1L.
