一种基于任务的传感器-中心整体能耗模型

A Task Based Sensor-Centeric Model for overall Energy Consumption

Najmeh Kamyabpour, Doan B. Hoang

摘要:

传感器的资源有限,因此有效地管理资源以最大限度地利用资源是很重要的。传感器的电池是一个关键的资源,因为它单独决定了传感器网络应用的寿命。由于这些设备只有在能够与世界通信时才有用,因此传感器的无线电收发器作为I/O和昂贵的单元在其寿命中起着关键作用。该资源通常消耗传感器能量的很大一部分,因为它必须在大部分时间处于活动状态以通告网络中传感器的存在。因此,无线电组件必须处理其嵌入式传感器网络,其参数和操作对传感器的寿命有显着影响。在现有的能量模型中,考虑了硬件,但环境和网络的参数没有得到足够的重视。传统的网络架构的能耗组件往往被单独和分开考虑,它们之间的相互影响在这些方法中没有被考虑。在本文中,我们考虑所有可能的任务的传感器在其嵌入式网络,并提出了一个能量管理模型。我们将这些任务分为五种能源消耗成分。传感器的能量消耗(EC)是根据其能量消耗成分及其输入参数和任务建模的。因此,可以通过有效地管理和执行其组成部分的任务来减少传感器的EC。该方法可以有效地进行能量管理,并可用于指导能量有效的无线传感器网络的设计,通过网络参数化和优化。

英文摘要:

Sensors have limited resources so it is important to manage the resources efficiently to maximize their use. A sensor's battery is a crucial resource as it singly determines the lifetime of sensor network applications. Since these devices are useful only when they are able to communicate with the world, radio transceiver of a sensor as an I/O and a costly unit plays a key role in its lifetime. This resource often consumes a big portion of the sensor's energy as it must be active most of the time to announce the existence of the sensor in the network. As such the radio component has to deal with its embedded sensor network whose parameters and operations have significant effects on the sensor's lifetime. In existing energy models, hardware is considered, but the environment and the network's parameters did not receive adequate attention. Energy consumption components of traditional network architecture are often considered individually and separately, and their influences on each other have not been considered in these approaches. In this paper we consider all possible tasks of a sensor in its embedded network and propose an energy management model. We categorize these tasks in five energy consuming constituents. The sensor's Energy Consumption (EC) is modeled on its energy consuming constituents and their input parameters and tasks. The sensor's EC can thus be reduced by managing and executing efficiently the tasks of its constituents. The proposed approach can be effective for power management, and it also can be used to guide the design of energy efficient wireless sensor networks through network parameterization and optimization.
