A Data Processing and Analysis Testbed for WSNs: Design and Implementation

In this paper, we design and implement a reliable data processing and analysis test bed (NESCTB) for wireless sensor networks (WSNs). It contains 36 wireless sensor nodes connected through Ethernet to a central server so that, with web interface, remote users are able to schedule tasks and monitor the nodes' operations online. In addition, reprogramming and data logging can also be provided via the wired network. Powerful data processing and analysis tools are developed for information searching and processing, real-time topology visualization, 2-D and 3-D viewing of statistical diagrams, snapshots and timing sequences. The tools can significantly improve user-friendliness and operability of the test bed. The application scenarios of the test bed are discussed and a validation experiment for the referred application case NESCSurge demonstrates the convenience and effectiveness of NESCTB.
