Abstract

This work reports an image encoding scheme that distributes low-density parity-check (LDPC) encoding over a prime field of order q, GF(q), on a wireless sensor network (WSN). In the scheme, we divide the input data into several small parts, which are then distributed to multiple nodes to perform a LDPC encoding task in a cluster. We conducted extensive computational simulations to verify our method and found that the LDPC codes over GF(4) achieve a fair trade off between the bit error rate (BER) and power consumption criteria. As a result, the proposed scheme of using LDPC codes over GF(4) not only solves the energy balance problem by sharing processing tasks but also increases the data quality.
