【摘要】 低能量消耗是无线传感器网络数据传输中面临的设计挑战之一。分别对直接传输、多跳传输、混合传输以及能量平衡传输的总能量消耗进行了比较,并指出了它们各自的缺点,从而提出了一种基于可变范围传输策略的能量优化与能量平衡算法。仿真结果表明,该算法不仅明显降低了网络的总能耗,而且降低了网络中各个节点的能量消耗不平衡。更多还原

【Abstract】 Low energy assumption is one of design challenges for data transmission for sensor network. The total energy consumption rates of direct transmission, hop-by-hop transmission, direct-hop transmission and energy-balanced transmission are compared, and the drawbacks of the above transmissions is dentified respectively. Then, an algorithm between energy-optimized and energy-balanced by variable range transmission is presented. Simulation results show that the algorithm can not only minimize the total energy consumption obviously, but also keep the energy consumption balancing among the nodes.更多还原
