Abstract MIMO two-way relay network is well known as a method for realization of high efficiency wireless relay network. In recent research studiis MIMO two-way relay network has maximum throughput in equidistant topology. But such a topology rarely exists in practical situation. In a non-equidistant topology, end-to-end network capacity evaluated at link bottleneck degrades severdy due to uneven SINR. In this paper, we focused on a non-equidistant topology at MIMO two-way relay network, and proposed three transmit power allocation schemes for balancing SINR. i.g., Centralized power allocation schemes(Power Allocation based on Perron-Frobenius Eigen-value, Power Allocation based on Optimization Problem, and Distributed Power Allocation), examine improvement of the flexibility of the network topology. In last, proposed schemes are evaluated using computer simulator.
