ns-3 RELEASE NOTES
This file contains ns-3 release notes (most recent releases first).
All of the ns-3 documentation is accessible from the ns-3 website:
http://www.nsnam.org including tutorials: http://www.nsnam.org/tutorials.html
Consult the file CHANGES.html for more detailed information about changed
API and behavior across ns-3 releases.
Release 3.19
=============
Availability
------------
This release is available from:
http://www.nsnam.org/release/ns-allinone-3.19.tar.bz2
Supported platforms
-------------------
These platforms have been tested; others may work also:
- Fedora Core 20 (32 bit) with g++-4.8.2
- Fedora Core 19 (32/64 bit) with g++-4.8.1
- Ubuntu 13.10 (64 bit) with g++-4.8.1
- Ubuntu 12.04.3 (32/64 bit) with g++-4.6.3
- Ubuntu 10.04.4 LTS (64 bit) with g++-4.4.3
- OS X Mavericks 10.9 with Xcode 5.0.1 and clang-500.2.79
- OS X Mountain Lion 10.8.5 with Xcode 5 and g++-4.2.1
- FreeBSD 9.2-RELEASE (64 bit) with clang-3.3
New user-visible features
-------------------------
- Extension to UE measurements and improved handover algorithm models in LTE
module, as the outcome of GSoC 2013 project. The project also includes several
sub-features, such as:
- implementation of System Information Block Type 1 (SIB1);
- a new option for automatic UE attachment using Idle mode cell selection
procedure;
- improved configurability of UE measurements; and
- two options of handover algorithms for enabling automatic handover trigger
in LTE simulation: A2-A4-RSRQ and strongest cell (A3-RSRP).
- A new FixedRoomPositionAllocator has been added to the buildings
module. It allows one to generate a random position uniformly
distributed in the volume of a chosen room inside a chosen building.
- A new attribute ns3::LteRlcAm::TxOpportunityForRetxAlwaysBigEnough
allows to overcome the lack for re-segmentation in the RLC AM
implementation by assuming that the size of a TxOpportunity is
always big enough for the RLC AM PDU to be retransmitted.
- After some profiling, the code of LteMiErrorModel has been optimized
for speed, resulting in a significantly lower execution time of the
LTE model when used with the error model enabled.
- A new WiFi extension for vehicular simulation support is available in
the src/wave directory. The current code represents an interim capability
to realize an IEEE 802.11p-compliant device, but without the WAVE
extensions (which are planned for a later patch). The WaveNetDevice
modelled herein enforces that a WAVE-compliant physical layer (at 5.9 GHz)
is selected, and does not require any association between devices (similar
to an adhoc WiFi MAC), but is otherwise similar (at this time) to a
WifiNetDevice. WAVE capabililties of switching between control and
service channels, or using multiple radios, are not yet modelled.
- A new IPv6 over Low power Wireless Personal Area Networks (6LoWPAN) model
is available. Using ns-3's naming convention, the acronym is expanded
to SixLowPanNetDevice. The SixLowPanNetDevice is able to act as a
shim between IPv6 and a NetDevice, compressing IPv6 headers according
to RFCs 4944 and 6262. The SixLowPanNetDevice is meant to be used over
IEEE 802.15.4 NetDevices, but it can be used on other NetDevices as
well (see the manual for full details). This model precedes the
general availability of an 802.15.4 model, so must be run in conjunction
with a wired NetDevice model for now, or with experimental versions of
802.15.4 models.
- It is now possible to use Ipv6PacketInfoTag from UDP applications in the
same way as with Ipv4PacketInfoTag. See Doxygen for current limitations in
using Ipv[4,6]PacketInfoTag to set IP properties.
- Ipv[4,6]Interfaces not respecting the minimum MTU requirements (68 octects
for IPv4 and 1280 octects for IPv6) will be automatically set as Down.
- IPv6 addresses and routing tables are printed in a more conventional way,
closely matching the Linux "route -A inet6" command.
- Additional time units (Year, Day, Hour, Minute) were added to the time
value class that represents simulation time; the largest unit prior to
this addition was Second.
- A new parallel scheduling algorithm based on null messages, a common
parallel DES scheduling algorithm, has been added. The null message
scheduler has better scaling properties when running on some scenarios
with large numbers of nodes since it does not require a global
communication.

Release 3.18.2
==============
ns-allinone-3.18.2 was released to include a bake configuration file update
for Direct Code Execution. The ns-3 code in this release was unchanged
from that of ns-3.18.1.
Release 3.18.1
==============
This release is mainly to provide updated compiler support (clang/LLVM)
and fix the Python API scanning facility. A few additional bug fixes
and new features are described below.

access point. Use an attribute "EnableBeaconJitter" to enable/disable
this feature.
- A new FixedRoomPositionAllocator helper class is available; it
allows one to generate a random position uniformly distributed in the
volume of a chosen room inside a chosen building.
- Logging wildcards: allow "***" as synonym for "*=**" to turn on all logging.
- The log component list ("NS_LOG=print-list") is now printed alphabetically.
Bugs fixed

Release 3.15
============
Availability
------------
This release is available from:
http://www.nsnam.org/release/ns-allinone-3.15.tar.bz2
Supported platforms
-------------------
- Fedora Core 17 (32/64 bit) with g++-4.7.0
- Fedora Core 15 (64 bit) with g++-4.6.3

- FreeBSD 8.2 (32 bit) with g++-4.2.1
- Cygwin 1.7.9-1 with g++-4.5.3
New user-visible features
-------------------------
- A new random variable base class called 'RandomVariableStream', has been
introduced. This base class derives from ns3::Object, unlike the current
'RandomVariable' class which is a special type of object in the ns-3
system to date. By making this class derive from ns3::Object, it can be
handled with the Ptr class, can carry attributes, and can have its parameters
and initial state saved in the config-store subsystem. A new attribute
called "Stream" has been introduced for this class, to allow users to
better control the assignment of underlying pseudo-random sequences to
the RandomVariableStream objects (bug 101).

Release 3.14
============
Availability
------------
This release is available from:
http://www.nsnam.org/release/ns-allinone-3.14.tar.bz2
Supported platforms
-------------------
ns-3.14 has been tested on the following platforms. Not all features are
available on all platforms; check the Installation page on the project wiki.
- Fedora Core 17 (32/64 bit) with g++-4.7.0
- Fedora Core 16 (32/64 bit) with g++-4.6.3
- Fedora Core 15 (64 bit) with g++-4.6.3
- Ubuntu 12.04 (32/64 bit) with g++-4.6.3

- FreeBSD 8.2 (32 bit) with g++-4.2.1
- Cygwin 1.7.9-1 with g++-4.5.3
New user-visible features
-------------------------
- Transport protocol implementations (TCP, UDP) have been refactored to
support also IPv6 connections. Dual-stacked IPv6 sockets are implemented.
An IPv6 socket can accept an IPv4 connection, returning the sender's
address as an IPv4-mapped address (IPV6_V6ONLY socket option is not
implemented).
- The LTE code from the LENA project has been merged, bringing in a
significant redesign of the LTE module as well as many new features.
- An antenna module is now included, which includes different
radiation pattern models. See the corresponding new section of the
ns-3 models library documentation for details.
- A new buildings module is introduced which allows to model the
presence of buildings in a wireless network topology.
- New propagation models (OkumuraHata, ITU-R P.1411, ITU-R P.1238)
have been added
- The Dynamic Source Routing (DSR) MANET routing protocol for IPv4 was added.
- A Random Early Detection (RED) queue model has been added.
- Ipv6RoutingHelper is now in-line with Ipv4RoutingHelper concerning the RT
print functions. Various minor changes were made in Ipv6RoutingProtocol and
derived classes to make this possible.
- New "SendIcmpv6Redirect" attribute (and getter/setter functions) to
Ipv6L3Protocol. The behavior is similar to Linux's conf "send_redirects",
i.e., enable/disable the ICMPv6 Redirect sending.
- Longer and more descriptive names are used for error units in RateErrorModel
class and queue mode in Queue class. Attributes in those classes are also
changed for consistency. See API documentation for details.
- The netanim animator is now bundled with the release.

New user-visible features
-------------------------
- SpectrumChannel models now support the usage of single-frequency
propagation loss models based on the PropagationLossModel
class. These model can be used in conjunction with
the frequency-dependent propagation loss model based on the
SpectrumPropagationLossModel class already supported by
SpectrumChannel.
- Extend the attribute system extend the attribute system to store map
container objects in addition to vector containers. The ObjectMap
and related classes are patterned after ObjectVector.
- Support for IPv4 fragmentation has been added.
- Significant performance improvement for AODV in dense mobile scenarios
due to a fixed bug in RERR processing.
- WiFi traces that were named promiscuous are now renamed monitor, and
a separate flag for setting the interface to promiscuous mode has been
introduced. This disambiguates monitor mode from promiscuous mode.

Release 3.11
===========
Availability
------------
This release is available from:
http://www.nsnam.org/release/ns-allinone-3.11.tar.bz2
Supported platforms
-------------------
ns-3.11 has been tested on the following platforms. Not all features are
available on all platforms; check the Installation page on the project wiki.
- Linux x86_64 Ubuntu 11.04
- g++-4.5.2
- Linux i686 Ubuntu 11.04
- g++-4.5.2, g++-4.4.5
- Linux x86_64 Fedora Core 15
- g++-4.6.0
- Linux x86_64 Fedora Core 14

- OS X Snow Leopard
- g++-4.2.1
New user-visible features
-------------------------
- The build system has been modularized, and the source code reorganized,
to allow for modular libraries instead of a single monolithic ns-3
library. User programs now link a number of smaller, per-module
libraries depending on the dependencies expressed to the build system.
Source code is now being maintained in individual modules with
consistent directory structures.
- Python bindings have also been modularized, and the bindings are now
generated into a 'ns' namespace instead of 'ns3' for the old
(monolithic) bindings. By default the bindings are now modular, with
a backward compatibility layer for older programs.
- By default, example and test programs are disabled from the build.
Users can enable them via the use of a waf command at configure time,
or automatically through the use of a new .ns3rc file.
- int64x64_t is a new type which allows portable and easy to write arithmetic
calculations that require a high degree of fractional precision.
- An interface to the Click Modular Router and an Ipv4ClickRouting
class has been added, to allow a node to use Click for external routing.
- An interface to an OpenFlow software implementation distribution has
been added to allow the simulation of OpenFlow switches in ns-3.
- ns-3 coding style requirements have been applied to the entire coding
base, resulting in a large number of whitespace changes. The coding
style has been automatically enforced by running a style checking
program (utils/check-style.py) that uses the uncrustify (v. 0.58)
program to apply changes.
- Some documentation reorganization to split documentation between
the ns-3 manual (primarily focusing on the ns-3 core) and a new
"model library" document has been started.

Release 3.10
===========
Availability
------------
This release is available from:
http://www.nsnam.org/release/ns-allinone-3.10.tar.bz2
Supported platforms
-------------------
ns-3.10 has been tested on the following platforms. Not all features are
available on all platforms; check the Installation page on the project wiki.

- OS X powerpc Leopard
- g++-4.0, g++-4.2
New user-visible features
-------------------------
- NS-3 PyViz, a live simulation visualizer, has been added. The
visualizer interacts with a running simulation, such that it uses no
trace files. It can be most useful for debugging purposes, i.e. to
figure out if mobility models are what you expect, where packets are
being dropped, etc. There is also a builtin interactive python console
that can be used to debug the state of the running objects. Although
it is mostly written in Python, it works both with Python and pure C++
simulations.
- Wi-Fi MAC high classes have been reorganised in attempt to
consolidate shared functionality into a single class. This new
class is RegularWifiMac, and it derives from the abstract
WifiMac, and is parent of AdhocWifiMac, StaWifiMac, ApWifiMac,
and MeshWifiInterfaceMac. The QoS and non-QoS class variants are
no longer, with a RegularWifiMac attribute "QosSupported"
allowing selection between these two modes of
operation.
- Support for IEEE 802.11g (specifically, rates with Modulation
Class ERP-OFDM) has been added to the wifi module. The new
WifiModes have names of the form ErpOfdmRatexxMbps, where xx is
the rate in Mbps (one of 6, 9, 12, 18, 24, 36, 48, 54), and a
WifiPhyStandard enumeration WIFI_PHY_STANDARD_80211g has been
added to allow configuration of a Wi-Fi STA supporting ERP-OFDM,
HR/DSSS, and DSSS rates (which some call an "802.11b/g" station).
- Two attributes were added to WaypointMobilityModel. The first
"LazyNotify" (default false), if enabled to true, will suppress
course change notifications if there are no position updates.
The second, "InitialPositionIsWaypoint" (default false), if enabled,
will allow an initial call to SetPosition () (before any waypoints
have been added) to be treated as the first waypoint.
- Regression testing is now completely performed within test.py
rather than a separate "./waf --regression" that consults
