TKN Wireless Indoor Sensor network Testbed
Welcome
The TKN Wireless Indoor Sensor network Testbed (TWIST), developed by the Telecommunication Networks Group (TKN) at the Technische Universität Berlin, is a scalable and flexible testbed architecture for experimenting with wireless sensor network applications in an indoor setting. It provides basic services like node configuration, network-wide programming, out-of-band extraction of debug data and gathering of application data, as well as several novel features:
- experiments with heterogeneous node platforms
- support for flat and hierarchical setups
- active power supply control of the nodes
The self-configuration capability, the use of hardware with standardized interfaces and open-source software makes the TWIST architecture scalable, affordable, and easily replicable.
TWIST Instance at TKN
Overview
Our local TWIST instance is one of the largest academic testbeds for indoor deployment scenarios. It spans the three floors of the FT building at the TU Berlin campus, resulting in more than 1500 m2 of instrumented office space. Currently the setup is populated with two node platforms:
102 TmoteSky nodes
- 102 eyesIFX nodes
In the small rooms, two nodes of each platform are deployed, while the larger ones have four nodes. The setup results in a fairly regular grid deployment pattern with intra node distance of 3m.
