[Ns-developers] Latest release of NS-3 WiMAX module

[Jahanzeb Farooq]

Hi all,
I hereby announce the latest release (version 1.0) of the WiMAX module
for NS-3. A number of functionalities have been added since the last
release on May 28, 2008. Major new additions are outlined below very
briefly.

- Scheduling services, which includes all four scheduling services
defined by 802.16 standard, namely UGS, rtPS, nrtPS and BE. The uplink
scheduler has been updated to support these scheduling services. The
scheduler supports a simple FCFS based scheduling algorithms.

- Service flow management of service flows, which includes creation and
management of service flows of the four scheduling services.
SS-initiated DSA mechanism is supported in which SS requests the BS for
creation of a service flow, specifying the associated QoS parameters,
and BS then creates the service flow and the associated transport
connection. 

- Bandwidth management, which includes bandwidth request and grant
mechanism, a key feature of the WiMAX scheduler in which a service flow
requests the BS for bandwidth based on its needs and BS responds by
allocating the service flow with sufficient bandwidth. Besides this
bandwidth manager works together with the uplink scheduler to determine
total bandwidth available and allocation size for each service flow.

For a more detailed version of the additions and updates since last
release please refer to the README file under src/devices/wimax/.

At the time of last release the code only worked with the development
release of the IT++ library. The code has now been updated to work with
the stable version of the library. Currently it is working with the
stable version 4.0.4 and has been tested with the latest version 4.0.5
as well.

The code has been merged to the latest development version of NS-3
(ns-3-dev) a few minutes ago.

The code is currently located at the link below:
