Power Consumption Benchmarking of TinyOS Applications with A Dedicated Measurement Adapter

Wireless sensor networks need to operate as long as possible under battery power, which makes reducing node power consumption a primary design goal for wireless sensor networks. In order to better understand power consumption characteristics of sensor nodes, it is necessary to establish power consumption benchmarking for typical example applications. To achieve this goal, this paper designs a dedicated adapter board for power measurement and uses it to perform power consumption tests on typical TinyOS example applications. Experimental results show that using the proposed adapter, not only can the overall power consumption of sample applications be quickly analyzed, but also the details of voltage and current changes can be deeply understood.
