Low density parity check code in cooperative MIMO communication at wireless sensor network

Energy efficient data transmission is one of the key factors for energy constrained wireless sensor network. Cooperative communication explores the energy efficient wireless communication schemes between multiple sensors and data gathering node. In this paper, an energy efficient cooperative multiple input multiple output technique, which uses low density parity check codes, is suggested. The result shows that the suggested cooperative communication technique outperforms single input single output transmission with error correction code. Bit error rate analysis is also performed.
