1. AAA/SWITCH Info Day 2010 Project Idea: A 4 -Mesh Thomas Staub and Torsten Braun University of Bern, Switzerland

2. A 4 -Mesh: Motivation Thomas Staub, 13.01.2010 Project Idea 2  Not all locations are sufficiently covered with broadband network services for research and daily operation.  Wireless Mesh Networks could enhance network coverage of the universities.

3. A 4 -Mesh: Motivation II  Broadband network access to campus networks in remote areas / in case of events  Research and applications in the following fields require broadband network access in remote areas: —Environmental monitoring —Agricultural monitoring —Weather monitoring —Biology —Surveillance of restricted areas —Avoidance and investigations of environmental offenses Thomas Staub, 13.01.2010 Project Idea 3  Cost-efficient network access, easily deployable, integrated in normal authentication and authorization infrastructure (SWITCHaai)

4. A 4 -Mesh: Goals  Easily deployable, cost-efficient, and functional wireless mesh infrastructure including: —Authentication and Authorization – Network node authentication (SWITCHaai / IEEE 802.11x) – Client authentication (SWITCHaai / IEEE 802.11x) – Authorization of users and administrators (SWITCHaai / eduroam) —Accounting – Traffic accountable to individual users – Monitoring network conditions (self-awareness) – Distributed accounting architecture —Auditing – Detection of inconsistent or erroneous node states, autonomous recovery / alarms – Increased network robustness and low maintenance costs by self- healing mechanisms Thomas Staub, 13.01.2010 Project Idea 4

5. A 4 -Mesh: Planned Activities  Indoor test beds (UniBE, UniNE) —Development networks  Outdoor test bed (Payerne – Neuchâtel) —Testing of A 4 -Mesh in a deployment for environmental research Thomas Staub, 13.01.2010 Project Idea 5

6. A 4 -Mesh: Planned Activities  Pilot network at UniBE (area of INSEL hospital) —Pilot with real users, integration in existing campus WLAN infrastructures  Public demonstrations  Publicly available source code Thomas Staub, 13.01.2010 Project Idea 6

7. A 4 -Mesh: Partners  Insitut für Informatik und angewandte Mathematik, UniBE  Institut d‘informatique, UniNE  IT services, UniBE  IT services, UniNE  SWITCH  We are currently searching for additional end users ( IT departments, environmental research, etc.).
