Efficient energy management is a major challenge in the operation of Wireless Sensor Networks due to their limited battery resources. In this paper, a cross-layer design (CLD) framework is proposed to jointly design the Physical layer and the DRMACSN MAC for Wireless Sensor Networks to achieve the energy conservation in the system. The system performance by combining adaptive modulation and the channel load blocking technique to maximize the network lifetime is provided. The simulation results show that the proposed CLD achieves significant energy saving as well as improved node lifetime.
