Improving the QoS of Wireless and IoT Networks Employing Bit Coupled Recursive Encoder-Decoder Architecture

The paradigm of IoT and wireless networks consist of a large number of low-power devices communicating over unreliable wireless channels. These devices are often deployed in harsh environments where noise, interference, fading, and packet loss are common. Reliable data transmission is therefore a critical requirement in IoT systems. Error detection and correction techniques play a vital role in ensuring data integrity without excessive retransmissions. Among advanced channel coding techniques, Turbo codes are known for their near-Shannon-limit performance and are highly effective in correcting errors in noisy communication envionments. The proposed technique attains lower bit error rate performance compared to the conventional un-coded and hard coded counterparts. A comparative analysis with respect to the error rate has been done so as to evaluate the quality of service of the proposed work. The lower error rate of the proposed work ensures the high quality of service and trustworthiness of the IoT system.
