    • Disclosed are an apparatus and a method for determining transmission power of a node. The apparatus for determining transmission power of a node includes a function calculation unit to calculate a relation function between a wireless signal transmission distance of the node and a data throughput of the node (transmission distance-data throughput function) using a time delay at a physical layer, a time delay at an MAC layer, and a time delay at a network layer using the wireless signal transmission distance of the node as a variable; a transmission distance determination unit to determine the wireless signal transmission distance of the node using the transmission distance-data throughput function and a threshold data throughput required for the node; and a transmission power determination unit to determine the transmission power of the node using the determined wireless signal transmission distance of the node. The time delay at the network layer corresponds to a ratio of a maximum possible wireless signal transmission distance to the wireless signal transmission distance of the node serving as the variable.
    • 公开了一种用于确定节点的传输功率的装置和方法。 用于确定节点的发射功率的装置包括:功能计算单元,用于使用物理上的时间延迟来计算节点的无线信号传输距离与节点的数据吞吐量之间的关系函数(传输距离数据吞吐量功能) 层,MAC层的时延,以及使用节点的无线信号传输距离作为变量的网络层的时间延迟; 传输距离确定单元,用于使用所述传输距离数据吞吐功能和所述节点所需的阈值数据吞吐量来确定所述节点的无线信号传输距离; 以及发送功率确定单元,用于使用所确定的所述节点的无线信号传输距离来确定所述节点的发送功率。 网络层的时间延迟对应于最大可能的无线信号传输距离与作为变量的节点的无线信号传输距离的比率。
