Abstract
Cooperative multiple-input multiple-output (MIMO) based communication architecture are used for energy efficient communication in wireless sensor networks. 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.
