This code is a modification and extension of ns-2 to support impulse radio UWB wireless networking. The two main components that are added to the plain ns-2 is the DCC-MAC layer (mac-ifcontrol.{cc,h}) and a model of an impulse radio UWB physical layer (interference-phy.{cc,h}) assuming time-hopping, pulse position modulation and convolutional code for channel coding. As such, concurrent transmissions are possible thanks to the use of time-hopping. Our physical layer computes the packet error rate for each packet based on a bit error rate (BER) computation. The BER is calculated with lookup tables that map a signal to interference and noise ratio (SINR) to the BER. We also add a propagation model for UWB channels.

• The latest version of our code runs with ns-2.29.

Installation

• In order to download and install the most up-to-date ns-2 code of the UWB MAC and PHY layers, follow the installation instructions.

NOAH Routing Agent

• Our code includes the NOAH routing agent. If you want to install and run NOAH separately, you can obtain it here. Yes, NOAH does work with ns-2.29 (and ns-2.30). Simply follow the instructions given. NOAH was written and is maintained by Jörg Widmer.

Documentation and Related Publications

• There is some documentation available. The documentation is far from exhaustive so do not hesitate to ask questions by sending an email to Ruben Merz.
• Here is a list of related publications with UWB and ns-2:
  • Article that describes our work on ns-2: "An Architecture for Wireless Simulation in NS-2 Applied to Impulse-Radio Ultra-Wide Band Networks" written by R. Merz, J.-Y. Le Boudec and J. Widmer (abstract and .pdf).
  • Article that describes the latest version of the DCC-MAC protocol: "A joint PHY/MAC architecture for low-radiated power TH-UWB wireless ad-hoc networks" written by R. Merz, J. Widmer, J.-Y. Le Boudec and B. Radunovic (abstract and .pdf).
