ENERGY EFFICIENCY SIMULATION BASED ON VIRTUAL MIMO-BASED COOPERATIVE COMMUNICATION FOR WIRELESS SENSOR NETWORKS
RESUMO
For energy limited cooperative wireless sensor networks, an energy efficient virtual multiple input multiple output (MIMO) based communications architecture is proposed. The energy efficiencies of the proposed MIMO-based communications scheme are derived using analytical techniques while assuming a space time block coding (STBC) for the MIMO system. The communication system and the channel propagation parameters define the efficiency of the proposed system. In this paper, we investigate cooperative MIMO for fixed and variable rates. We propose energy efficient routing based on cooperative MIMO. In wireless sensors networks, the nodes are operating on batteries so that energy consumption must be minimized while satisfying given throughput and delay requirement. Simulations show that with proper design, Cooperative MIMO based routing is more energy efficient as compared to single input single output (SISO) for larger distances and prolong sensor network lifetime.
