What is CentMesh ?
• CentMesh : a project to build a versatile, open source shared resource on campus
• Provide an active testbed to support research and instruction on wireless networks
• Part of NCSU’s “Living Laboratory” vision

What is a “Mesh Network”?
• Multihop wireless• Stationary backbone – mobile routers and clients• Some nodes have Internet access – other share• Advantages: Cheaper, less infrastructure, more agile
deployment, more intelligence in network• Potential: Metro area, municipal networks, tactical,
vehicular, smartgrid, healthcare…

• Homemade !– Built by NCSU student researchers– Guided by NCSU faculty– Funded by Army Research Office and NCSU– Operationalized by Institute of Technology of
Next Generation (ITng), NCSU
First (shoestring) attempt at mobile nodes – didn’t work too well !

What is CentMesh made of ?
• Commodity PCs and WiFi cards – no proprietary• Open source community software• Open source software designed and built by NCSU
student and faculty researchers• Currently at 14 poletop and rooftop nodes, 8
mobile nodes, 5 labbench nodes

How did we design CentMesh ?
• Modular programming library• Clear separation of data, control, management
functions• Easy to innovate in some or many parts, keep
others unchanged
