Abstract

The emerging area of body area networks (BAN) imposes challenging requirements on hardware and software to achieve the desired lifetimes for certain devices such as long term medical implants. In this paper, we propose a novel approach to the measurement and characterisation of the energy consumption of BAN devices. The approach uses a low cost energy auditing circuit and addresses the problem of accurately measuring low-level current consumption. This new technique will allow precise and analytical measurements of systems and components in terms of energy. This will help circuit designers minimise power consumption in BAN devices. Software engineers might use this approach to validate and optimise embedded code. Network engineers can optimise network parameters to reduce the power consumption of a single node. Adoption of the proposed technique will aid the development of ultra-low power wireless BANs. Results are presented on current characterisation for two wireless motes.
超低功耗无线体域网络的电流特性
新兴的身体区域网络(BAN)对硬件和软件提出了具有挑战性的要求,以实现某些设备(如长期医疗植入物)的预期寿命。在本文中,我们提出了一种测量和表征BAN器件能耗的新方法。该方法采用低成本的能量审计电路,解决了精确测量低电平电流消耗的问题。这项新技术将允许在能量方面对系统和组件进行精确的分析测量。这将有助于电路设计者将BAN器件的功耗降至最低。软件工程师可能会使用这种方法来验证和优化嵌入式代码。网络工程师可以通过优化网络参数来降低单个节点的功耗。采用所提出的技术将有助于超低功耗无线ban的发展。给出了两种无线粒子的电流表征结果。
