Wireless Sensor Networks (WSNs) have limited energy resource which requires authentic data transmission at a minimum cost. The major challenge is to deploy WSN with limited energy and lifetime of nodes while taking care of secure data communication. The transmission of data from the wireless channels may cause many losses such as fading, noise, bit error rate increases as well as deplete the energy resource from the nodes. To reduce the adverse effects of losses and to save power usage, error control coding (ECC) techniques are widely used and it also brings coding gain. Since WSN have limited energy resource so the selection of ECC is very difficult as both power consumption, as well as BER, has also taken into consideration. This research paper reviews different types of models, their applications, limitations of the sensor networks, and what are different types of future works going to overcome the limitations.
