摘要
介绍了移动自组网的特点和802.11 DCF传输方式,论述了自组网的动态节能机制,提出了一种通过交换控制信息来预测最小发射功率的功率自适应调整MAC协议。仿真实验证明了该方案能有效降低系统的能量消耗,提高了网络的利用率。
This paper introduces the MANET and the transmission mode of 802.11 DCF protocol. The dynamic energy-save mechanism in Ad Hoc networks is discussed, and a new power-adaptive control protocol is proposed based on the exchange of the control information to estimate the minimal transmission power. The experiments prove that the protocol can efficiently reduce the energy consumption and improve the utilization of the network.
