There has been a dramatic push to adopting wireless networking technologies and protocols (such as 802.11, ZigBee, WirelessHART, Bluetooth, ISA100.11a, etc.) into time-critical networks. End-to-end latency is critical to many distributed applications and services that are based on computer networks. Examples of such applications include telecommunications, power utility, financial services, and industrial automation. While performance measurement of wired networks has been extensively studied, measuring and quantifying the performance of wireless networks face new challenges and demand different approaches and techniques. In this paper, we describe a measurement platform based on the technologies of software-defined radio (SDR) and IEEE 1588 Precision Time Protocol (PTP) for measuring and evaluating the performance of wireless networks (including wireless sensor networks). By evaluating the performance metrics described in the paper, application behaviors based on robust time synchronization could be better quantified and evaluated.
