WINSE and error correction methods in WiMAX

Henrik Martikainen

WINSE is a WiMAX extension to NS-2 which is an open source packet
simulator. WINSE has been under development by WIMALE project here
at the MIT department since 2006 and it has a very wide range of
WiMAX features implemented even in a global scale. I have used the
simulator to study different error correction methods in WiMAX.
Errors are always present with wireless transmissions. WiMAX has
two error correction methods to provide an error free channel to
the applications. These are Automatic Repeat Request (ARQ) and
Hybrid ARQ (HARQ). In my presentation I will introduce WINSE/NS2
simulator, give a brief overview on ARQ/HARQ methods and show how
do they work in different situations.
