What is centmesh

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?


Ncsu s centennial campus a living laboratory

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”?
