摘要: 针对一种移动基站协助数据收集模式,研究移动基站最佳缓冲区位置的设计问题,得出节点在发射半径r=R的情况下,当移动基站缓冲区的中心位于2/3 时,网络的总能量消耗最小,当中心位于1/2R时,网络的寿命最长。在r<<R的情况下,节点的发射功率可选择 中的一种传送数据,并给出通过插值作图法得到最佳基站缓冲区位置的设置与节点最佳发射功率的计算方法,相比采用固定功率发射方法,能够将网络寿命提高5倍。

Abstract: This paper aims at a mobile base station data collection mode, the best location of the buffer zone of mobile base station is studied. The conclusions include that when nodes radius of the transmitting r=R, the total energy consumption is minimize when the centre of the data buffer is located on 2/3R. The network longest life is expectancy when the centre of the data buffer is located on 1/2R. When the situation is r<<R, the transmitter power level of nodes can be chosen from . The optimal location of the buffer zone and transmitter power level are given. Compared with fixed-fired power method, this method can greatly improve network life.
