Energy Efficiency about Collaborative MIMO Technology

摘要

Main energy consumption of wireless sensor nodes is used to send and receive data. To take measures to reduce sending and receiving energy consumption of nodes plays an important role in decreasing energy consumption of the whole network. Researches show that: under the requirements of the same throughput, sending the same information, dissipative energy of Multi-input multi-output (MIMO) systems are less than single-input single-output (SISO) systems. Therefore, introducing the MIMO technology in the wireless sensor networks (WSNs) can save the sending energy consumption of the network.
