Abstract: The topology control optimizes wireless networks by adjusting nodes transmission power or other performance index. Meanwhile, nodes in heterogeneous wireless network possess different features, which obstructs the optimization of wireless network with the traditional topology control algorithms developed from homogeneous networks. This paper proposed a kind of topology control model by introducing SINR into topology model, in order to solve the interference caused by nodes different transceiver gains. By adopting hierarchical clustering algorithm, new topology control strategy could improve the performance of heterogeneous wireless networks, which is supported by simulations.
