无线传感器网络功耗测试平台

A Power Test Platform for Wireless Sensor Network

一般针对无线传感器网络的测试往往注重单个设备的性能指标,这些测试比较单一,不能对如网络生存周期、数据传输延迟等指标进行测量,并且这些指标需要在被测网络节点之间相互协作通信的情况下完成。为改善测试方法,提出了一种解决无线传感器网络功耗测试平台,设计了一种测试网络,其包括测试设备和协调器,整个测试网络采用类似TDMA方式进行信道访问和时间同步,实现了对被测网络生命周期进行推算及通过各个设备状态的变化来验证网络的通信协议。

General tests for wireless sensor networks tend to focus on individual device performance, but these tests are relatively confined not only because they can not measure network life cycle and data transmission delay, etc., but because these metrics are dependent on the cooperative communication of network nodes. To improve testing methods, a platform for wireless sensor network is proposed, in which a test network is designed, including test equipment and coordinator. The test network accesses channel and synchronizes time using TDMA. On one hand, network life cycle can be calculated. On the other hand, the effect of communication network protocol is verified through the state change of equipments.
