In this paper, we propose a topology control algorithm for constructing an energy-efficient spanning subgraph for a wireless multi-hop network. The constructed topology has the following properties: (1) it preserves a minimum-energy path between every pair of nodes; (2) it is biconnected, i.e., it can tolerate any one node failure and avoid network partition. Simulation results show that the constructed topology has a small average node degree, a small average transmission range and a constant power stretch factor.
