In this paper, we have proposed a hybrid adaptive coding and de- coding scheme for multi-hop wireless sensor networks (WSNs). Energy con- sumption and transmission reliability are used as performance metrics for multi-hop communications in WSNs. The presented scheme takes into account distance, channel conditions and correction codes performance to decide coding and decoding procedure, and considers Reed Solomon (RS) code and Low Den- sity Parity Check (LDPC) code to provide error protection on the transmitted data. The proposed approach aims to reduce the decoding power consumption and to prolong the lifetime of the network as well as improve the reliabil- ity of the transmission. Simulation results show that our performed scheme enhances both energy effciency and communication reliability of multi-hop sensor networks.
