Yunpeng Cheng · Modern Electronics Technique · 2010
The space-time block code of distributed virtual multi-antenna based on four cooperative nodes and a power-harvesting node is investigated and designed proceeding with the energy efficiency of the nodes and the reliability of the transmitted data in wireless sensor network(WSN).Considering the actual environment and the rigorous demand for the energy,the energy of the cooperative nodes,the improved algorithm that reselects dynamic cooperative nodes from the channel parameter and node energy residue condition is proposed and analyzed to improve the system performance.The theory and simulation show that the application of the distributed space-time codes in WSN is effective and feasible.
