Selection of error control/correction codes in wireless sensor network

Error control coding (ECC) is a classic approach used to increase link reliability and lower the required transmitted power. It provides coding gain, resulting in transmitter energy savings, at the cost of added decoder power consumption. But the choice of ECC is very critical in the case of wireless sensor network (WSN). Since the WSNs are energy constraint in nature, both the BER and power consumption has to be taken into count. This paper develops a step by step approach in finding suitable error control codes for WSNs. Several simulations are taken considering different error control codes and the result shows that the RS(31,21) fits both in BER and power consumption criteria.
