1. An automotive sensor network system to detect communication faults in a communication link and avoid safety critical failure, the automotive sensor network system comprising:

  • a transceiver configured to receive at least one data-frame and a first package checksum from a source location, wherein the at least one data-frame includes a first data-frame checksum calculated at the source location;

    a source component configured to generate a determination of the source location from which the at least one data-frame is received;

    a data-frame decoder component configured to calculate a second data-frame checksum for the at least one data-frame by generating a first decoding method based on the determination of the source and compare the second data-frame checksum with the first data-frame checksum; and

    a package decoder component configured to calculate a second package checksum for a plurality of the data-frames received from the transceiver by generating a second decoding method based on the source location and compare the second package checksum with the first package checksum.
