动态协作化学传感器网络的建模与性能分析
Modelling and Performance analysis of a Network of Chemical Sensors with Dynamic Collaboration
摘要：
被认为是使用有限的能源供应的化学传感器的无线网络的环境监测的问题。由于传统的化学传感器在主动模式下消耗大量的能量，因此在这种网络的能量消耗和检测能力之间的平衡的背景下出现了优化问题。采用基于“动态传感器协作”的协议：在没有任何污染物的情况下，大多数传感器处于睡眠（被动）模式;只有当需要更多信息时，才通过来自其邻居的唤醒消息调用（激活）传感器。本文提出了一个数学模型的网络化学传感器使用该协议。该模型为网络行为和接近最优的容量设计（能耗与检测）提供了有价值的见解。一个分析模型的环境，利用湍流混合捕捉混乱的波动，不稳定性和非均匀性的污染物分布，在研究中。假设化学传感器的二元模型（具有阈值检测的设备）。研究的结果是一组简单的分析工具，传感器网络的设计，优化和性能分析。
英文摘要：
The problem of environmental monitoring using a wireless network of chemical sensors with a limited energy supply is considered. Since the conventional chemical sensors in active mode consume vast amounts of energy, an optimisation problem arises in the context of a balance between the energy consumption and the detection capabilities of such a network. A protocol based on "dynamic sensor collaboration" is employed: in the absence of any pollutant, majority of sensors are in the sleep (passive) mode; a sensor is invoked (activated) by wake-up messages from its neighbors only when more information is required. The paper proposes a mathematical model of a network of chemical sensors using this protocol. The model provides valuable insights into the network behavior and near optimal capacity design (energy consumption against detection). An analytical model of the environment, using turbulent mixing to capture chaotic fluctuations, intermittency and non-homogeneity of the pollutant distribution, is employed in the study. A binary model of a chemical sensor is assumed (a device with threshold detection). The outcome of the study is a set of simple analytical tools for sensor network design, optimisation, and performance analysis.
