无线传感器网络性能评价系统设计

Design of Evaluation System for Performance of Wireless Sensor Network

针对无线传感器网络的性能评价指标多样、缺乏统一标准的问题,设计了一种无线传感器网络性能评价系统。该系统包括频谱分析子系统、电流采集子系统和无线传感器监测子系统,能够对无线传感器网络的空中频谱特征、网络中节点的工作电流特征、网络丢包和吞吐量特性进行采集、统计与分析,实现对无线传感器网络的性能评价。

Aiming at the diversity of wireless sensor network performance evaluation indicators and the lack of unified standards,an overall evaluate system to assess the performance of wireless sensor network is designed.The system includes spectrum analysis subsystem,current acquisition subsystem and wireless sensor monitoring subsystem.The air spectrum,working current,network packet loss and throughout characteristics are acquired,counted and analyzed,and the performance evaluation of wireless sensor networks is realized.
