Reliable Low Power Wide Area Networks-Aided Polar Code

Low Power Wide Area Network (LPWAN) has emerged recently as a new IoT technology that offers wide coverage connectivity with low power consumption.However, this extraordinarily wide range and low-power performance come at the expense of high latency and low data rate.In 2008, Erdal Arkan proposed a new technique in the forwarding error correction mechanism, called polar codes, which offer a unique advantage of achieving channel capacity with low encoding and decoding complexity, scalability, and a low error floor, making them a compelling choice for error correction compared to other techniques.We used the polar codes mechanism in the LPWAN protocol to enhance error rate and data rate transmission.The performance of our approach demonstrated that polar codes can achieve an improved bit error rate at low data rates compared to the Hamming code technique used in LPWANs.For example, at 125 kHz, the Polar Codes signal-to-noise ratio outperforms the Hamming code used in LPWAN by 18 db.We can observe that at Spreading Factor 8, the Signal to noise ratio showed a better performance for our new code, polar code, with LPWAN for an error rate of 10 -5 .
