In this paper, the authors present various decoders for wireless sensor networks. Also reviewed many algorithms used for decoding purposes. Turbo codes have been recognized as a milestone in the channel coding theory. These are a class of error correcting codes that come closer to Shannon's limit than any other class of error correcting codes. Due to their outstanding error-correcting capabilities, turbo codes have been highly appreciated in wireless communications as well as in encoding and decoding algorithms. It mainly focuses on turbo decoder that is appreciable for wireless sensor networks. To reduce overall energy consumption, constant Log-MAP algorithm is used for decoding.
