The need to guarantee a real-timed reconstruction, modification and repair of unrecoverable request-to-send/clear-to-send (RTS/CTS) sensitive data packets in a typical military standard (MIL-STD-1553) network protocol for an industrial internet of battle things (IIoBT) is an emerging area of research investigation. This paper presents a method to reconstruct unrecoverable data in military standard MIL-STD-1553 using Biezier curves. The proposed method approximates and reconstructs data that was unrecoverable by error correction code technique. The proposed method aims at achieving reliable MILSTD-1553 protocol, which works on the real-time distributed system where re-transmission is not an optimal solution. The transmitted data which is damaged and may be unrecoverable is reconstructed by using the Biezier curve approximation. This method gives a refined effect on the damaged data that are normalized on the real-time transmission while a robust Cloud-Fog methodology was embedded to ensure data accessibility as demonstrated in the simulation works.
