Abstract—Link reliability and transmitted power are two important
design constraints in wireless network design. Error control coding
(ECC) is a classic approach used to increase link reliability and
to 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.
