Energy requirements of MIMO-based limited-energy wireless sensor networks are analyzed and simulated in the presence of the worst case cochannel interference and under different propagation conditions. The analysis and simulations were compared between three different types of systems, SISO, MIMO and MIMO with CSI. Results demonstrate the robustness of MIMO based wireless sensor networks in spite of the strong cochannel interference that may exist.
