  1. An extensible, programmable, open, real outdoor wireless network A teaching and research resource at NCSU Centennial centmesh.csc.ncsu.edu Welcome to the Centennial Mesh Network Testbed ! CoE Open House, March 2013 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 CentMesh?

  2. An extensible, programmable, open, real outdoor wireless network A teaching and research resource at NCSU Centennial centmesh.csc.ncsu.edu Welcome to the Centennial Mesh Network Testbed ! CoE Open House, March 2013 NCSU’s Centennial Campus – a “Living Laboratory”

  3. An extensible, programmable, open, real outdoor wireless network A teaching and research resource at NCSU Centennial centmesh.csc.ncsu.edu Welcome to the Centennial Mesh Network Testbed ! CoE Open House, March 2013 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… What is a “Mesh Network”?
