The present invention combines NC-aware routing and TDMA-based MAC protocol for energy-efficient design in the wireless network, and provides a method thereof. An optimization model, which is a minimum energy consumption model (MECM), is formulated for minimizing the energy consumption for accomplishing a set of flow transmissions.
