Abstract

We present an effective way to design and implement Reed Solomon codes in traditional wireless sensor networks.They are usually regarded as inappropriate in sensor networks despite their efficiency in terms of link reliability, because of their computational complexity which can require an important amount of energy. We use Galois field, over which code are built, features to reduce code energy consumption. We show that code with small symbol size are more suitable in sensor networks than code with standard symbol size of 8. Finally we propose a smart code selection schemeto tend towards nearly optimal RS code, according to application requirements.
