Mimo and Cooperative Mimo Comparison in Energy Constrained Wireless Sensor Networks

In Wireless Sensor Network commonly referred as WSN, the hubs or nodes are operated by batteries so that the energy utilization should be diminished, while fulfilling the given throughput and given requirement. The paper studies about the performance and energy consumption of cooperative MIMO and MIMO (multi input multi output) based communication. The average energy usage comprises circuit energy and transmission energy consumption. The comparison between the multi-inputmulti-output (MIMO) and cooperative MIMO techniques help us to choose the best scheme for energy constrained wireless sensor network application. The simulation result shows that energy efficiency of MIMO (multi-input-multi-output) and SISO (single-input-single-output) is better for longer distances and thud increase the system life time.
