摘　　要：由于无线传感网络中节点能够携带能量的有限,且能量补充复杂,所以如何高效利用无线节点的能量是无线网络面临的首要挑战。为解决上述问题,通过分析无线传感网络的特点和其能量损耗模型,提出了一种高效节能的跨层调度算法,仿真结果表明,算法能够很好的节约能量,同时降低数据传输延迟,最大化无线传感网络的生存时间。As the WSN nodes are limited in energy, and energy supplement is very complex, so how to use energy of the wireless node efficiently is the primary challenge faced by the WSN. In order to solve the problem proposed above, by analyzing the characteristics of WSN and its energy loss model, we propose a cross-layer energy-efficient scheduling algorithm. Simulation results are computed and the results are shown. The algorithm can save energy consumption efficiently and reduce data transmission delay. At the same time, the algorithm is able to prolong the lifetime of WSN.
