摘要
考虑一个多对一的传感器网络。在其中,一组传感器被放置在一个区域中用于监视该区域中的某一物理特性数值,一个中央基站收集这些数据并且构建对该物理现象的整体估值。给该网络定义了一个服务质量参数,并且提出了一种能够在满足给定的服务质量要求的基础上最小化网络中能量消耗的控制方案。理论推导和仿真实验均显示该方案有效并且能够快速收敛。
We consider a many-to-one wireless sensor network in which a large number of sensors are deployed to monitor a physical phenomenon in a local environment. A central base station is used to col- lect the observed data from the sensors to reconstruct the physical phenomenon After defining a quality of service for the network, we propose a control scheme for the network to satisfy any given quality of service requirement while minimizing the energy consumption in the network. Theoretical derivation and nu- merical experiments have shown that the scheme performs well and has a fast convergence rate.
