Finite Geometry Permutation Decoding for Wireless Sensor Network Applications

2017 Sensors and materials  
In this study, we propose a novel coding method, called geometry permutation decoding (GPD), for square sensor topologies. The GPD algorithm provides a two-dimensional geometry construction and decodes information sequences based on this construction. The two-dimensional construction for square wireless sensor networks (WSNs) is suitable for employing channel coding, especially product codes and finite geometry codes, and for detecting multiple error patterns. A majority logic decoding (MLD) is

To improve the drawback of the less correcting capacity, the GPD algorithm not only gives better bit error rates at low decoding complexity but also provides a new solution suitable for decoding in two-dimensional WSNs. In particular, this decoding work in the two-dimensional WSNs is achieved over the bit level without a packet level so that the overhead in the network layer can be reduced.
