Limited fidelity of simulators has prompted researchers to build wireless network testbeds for realistic testing. Unlike simulators, which have broad applicability, most of these testbeds are tailored to specific projects and cannot be used by a wider research community. Recognizing the growing importance of testbeds, this article is one of the first attempts to identify a comprehensive set of requirements for a general-purpose multihop wireless network testbed and the challenges therein. The issues range from initial testbed deployment and routine management to individual experimental configuration and data collection. We survey state-of-the-art wireless testbeds and highlight their salient features. The article is intended to provide an initial reference for researchers, application developers, and administrators dealing with various aspects of wireless network testbeds.
