Wireless Sensor Network (WSN) consists of large number of small sensor nodes to monitor physical or environmental conditions. The WSN depends on two major criteria: reliability of links and power consumption. Power supply in sensor nodes are often battery powered. Hence frequent service or sometimes replacement of sensor nodes is necessary. Error Correction Codes (ECC) is an efficient method to minimize the transmitted power. For the minimization of the power consumption of sensor nodes and to increase the lifetime of nodes, a systematic approach in finding suitable error correction codes for wireless sensor networks is followed in this paper.
