An adaptive cooperative MIMO transmission scheme in WSN

An energy-efficiency adaptive transmission scheme was proposed for energy-constrained wireless sensor networks.The number of cooperative antennas at both the transmission and the reception sides and modulation methods were selected jointly with respect to the different transmission distances and wireless channel environment in order to minimize the total energy consumption.Compared with the existing cooperation MIMO transmission schemes,the results showed that the proposed scheme can further improve the energy efficiency of wireless sensor network and have certain reference value in theory.
