Abstract:

Abstract： In practical wireless sensor networks, transmission channels are susceptible to interference, resulting in errors in the code. To ensure reliability of data transmission, we propose a simple and practical data transmission error correction scheme by integrating convolutional coding with interleaving technique. A flow chart is presented, and the approach is implemented on sensor nodes. The proposed method has low computation complexity, can resist high channel bit error, and is convenient to implement by software. Experimental results validate its effectiveness and practicality.
