In this paper we study the impact of error control code (ECC) on characteristic distance in wireless sensor network (WSN). In WSN nodes are energy constrained and the goal is to design an energy efficient network. Characteristic distance is important for such network. We consider Bose, Chaudhuri and Hocquenghem and Reed-Solomon codes with different error correction capabilities. Characteristic distance is studied for single node and all nodes transmitting case when decoding is done at all intermediate nodes and only at the destination node. The results show that there is significant improvement in characteristic distance when decoding is done at all intermediate nodes.
