We consider the cross-layer design considering physical layer, MAC layer, and network layer to maximize the lifetime of energy-constrained wireless sensor network. Our solution is based on system model that considers reliability as well as physical layer (i.e., power control), data link layer (i.e., link scheduling) and network layer (i.e., routing protocol) jointly. To obtain more energy-efficient solution for lifetime maximization of wireless sensor networks, we enhance existing cross-layer model using energy-efficient MAC protocol and its energy-consumption model.
