Ad Hoc网络中的动态反馈功率控制方法
Dynamic Feedback Power Control Method in Ad Hoc Network
摘要
Abstract
Traditional Ad Hoc networks transmit data with fixed maximum power, this working mode seriously affects the node and the network's lifetime which is limited by the energy stored in mobile node. To address the issue, this paper proposes to observe the linear change of Signal to Interference Ratio(SlR) of receiving node to calculate the required transmitting power of sending node, so as to dynamically adjust the transmitting power. Simulation results show that this method can effectively reduce the energy loss of nodes and increase the network lifetime.关键词
