Release 3.23
============
Availability
------------
This release is available from:
http://www.nsnam.org/release/ns-allinone-3.23.tar.bz2
Supported platforms
-------------------
This release has been tested on the following platforms:
- Ubuntu 15.04 (64 bit) with g++-4.9.2
- Fedora Core 21 (64 bit) with g++-4.9.2
- Ubuntu 14.04 (64 bit) with g++-4.8.2
- Ubuntu 12.04.4 (32/64 bit) with g++-4.6.3
- CentOS/RHEL 6.6 (64-bit) with g++-4.4.7
- OS X Yosemite 10.10.3 with Xcode 6.3.1 and Apple LLVM version 6.1.0
- FreeBSD 10.1-RELEASE (64 bit) with clang-3.4.1
New user-visible features
-------------------------
- (network) CalculateTxTime has been declared obsolete.
CalculateBytesTxTime and CalculateBitsTxTime are to be used instead.
The return value is a Time, instead of a double.
- (mobility) Classes added for converting geographic to cartesian coordinates.
- (spectrum) TvSpectrumTransmitter models added to create television
transmitter(s) that transmit PSD spectrums customized by attributes such
as modulation type, power, antenna type, channel frequency, etc.
- (wifi) Several model improvements have been made. Access points now
establish BSSBasicRateSet for control frame transmissions. PLCP header
and payload reception have been decoupled for improved PHY modeling
accuracy. RTS/CTS with A-MPDU is now fully supported, and 802.11n
stations now support two-level aggregation.
Bugs fixed
----------
- Bug 1757 - RLC AM not using NACK_SN

Release 3.22
============
Availability
------------
This release is available from:
http://www.nsnam.org/release/ns-allinone-3.22.tar.bz2
Supported platforms
-------------------
This release has been tested on the following platforms:
- Fedora Core 21 (64 bit) with g++-4.9.2
- Ubuntu 14.10 (32 bit) with g++-4.9.1
- Ubuntu 14.04 (64 bit) with g++-4.8.2
- Ubuntu 12.04.4 (32/64 bit) with g++-4.6.3
- CentOS/RHEL 6.6 (64-bit) with g++-4.4.7
- OS X Yosemite 10.10 with Xcode 6.1.1 and clang-600.0.56
- FreeBSD 10.1-RELEASE (64 bit) with clang-3.4.1
New user-visible features
-------------------------
- (wifi) Support for MPDU aggregation has been added to the wifi model,
as well as a number of related example programs.
- (wifi) Added two combined power and rate control mechanisms to the
wifi module. The new mechanisms, PARF and APARF, are the first in the
wifi module to jointly control transmission power and data rate. Two use
case examples (PowerAdaptationDistance and PowerAdaptationInterference)
and a test case have also been added.
- (lte) In previous releases of the LTE module, the bearer release
functionality was only partially supported. As an enhancement, a
complete release bearer procedure is now implemented, which can be
invoked by calling the new helper method
LteHelper::DeActivateDedicatedEpsBearer(). The related output can be
seen through the stats collected at different layers like PDCP, RLC,
MAC, PHY. To support this implementation, an example and test suite is
added within the LTE module examples and tests folder.
- (wave) Additional support has been added for WiFi-based vehicular networks,
including the channel-access coordination features of IEEE 1609.4 and a
comprehensive VANET routing example that includes a Basic Safety
Message (BSM) packet generator application and associated statistics
counters. Together, these allow users to evaluate the performance effects
in a VANET of varying transmission and channel properties (e.g., packet
rate, message size, transmit power, propagation loss model, impact of
routing protocol traffic, etc.).
- (internet) It is now possible to print the Neighbor Cache (ARP and NDISC)
by using the RoutingProtocolHelper
- (stats) A new TimeProbe class has been added to hook the data collection
framework to traced values emitting Time objects
- (documentation) the callback function signatures for all TraceSources
is documented in Doxygen
- (utils) print-introspected-doxygen.cc has had several enhancements;
use -h to read the usage message for details.
- (core) TracedValue and TracedCallback function signatures are now documented,
which required changing the TypeId::AddTraceSource API.
Bugs fixed
----------
- Bug 1405 - RttEstimator improvements
- Bug 1551 - NS_LOG_COMPONENT_DEFINE inside or outside of ns3 namespace?
- Bug 1726 - WiFi Minstrel rate control algorithm doesn't save state
- Bug 1734 - TcpSocketBase produces spurious delayed ACKs
- Bug 1758 - Yans and Nist error rate models for 5/6 code rate 802.11n HT
- Bug 1770 - mesh test and example crash for 32-bit optimized builds
- Bug 1774 - compute signal power around channel, not across whole band, and fix LrWpanHelper to add a default PropagationDelayModel
- Bug 1791 - TCP Endpoint never deallocates when closing
- Bug 1801 - Setting Wi-Fi timing parameters through WifiMac attributes (documentation fix)

Release 3.21
============
Availability
------------
This release is available from:
http://www.nsnam.org/release/ns-allinone-3.21.tar.bz2
Supported platforms
-------------------
- Fedora Core 20 (32/64 bit) with g++-4.8.2
- Ubuntu 14.04 (32/64 bit) with g++-4.8.2
- Ubuntu 12.04.4 (64 bit) with g++-4.6.3
- Ubuntu 10.04.4 LTS (64 bit) with g++-4.4.3
- CentOS/RHEL 6.5 (64-bit) with g++-4.4.7
- OS X Mavericks 10.9 with Xcode 5.1.1 and clang-503.0.40
- FreeBSD 9.2-RELEASE (64 bit) with clang-3.3
New user-visible features
-------------------------
- The LTE module now supports the transport of the S1-U, X2-U and X2-C
interfaces over emulated links via the new helper class EmuEpcHelper.
- CommandLine can now provide a shorthand argument name for any
Attribute.
- Implemented support for Frequency Reuse algorithms in LTE module, as the
outcome of GSoC 2014 project.
The project also includes several sub-features, such as:
- implementation of Downlink Power Control
- implementation of Uplink Power Control
- new DL-CQI generation approach, which increases throughput if FR algorithms
are used
- seven options of Frequency Reuse algorithms: LteFrNoOpAlgorithm,
LteFrHardAlgorithm, LteFrStrictAlgorithm, LteFrSoftAlgorithm,
LteFfrSoftAlgorithm, LteFfrEnhancedAlgorithm, LteFfrDistributedAlgorithm
- updated RadioEnvironmentMapHelper. Now RadioEnvironmentMap can be generated
for Data or Control channel and for specified RbId, what is helpful when
using FR algorithms
- Added a CoDel queue model. CoDel queues measure and control the queue
traversal delay. The ns-3 implementation is a port of the Linux
implementation.
- Added support for TCP timestamp and window scale options, and added
ability to trace the TCP slow start threshold value.
- SimpleNetDevice and SimpleChannel (used for adding basic link effects
for testing of higher-layer protocols) have been extended to support
the option of broadcast or PointToPoint link semantics. The bandwidth
and link delay can be constrained, and it uses an output queue.
- SimpleNetDevice and SimpleChannel can be installed in a node through
a new helper: SimpleNetDeviceHelper.
- Implemented new PacketSocketServer and PacketSocketClient applications.
The primary use is in tests, to avoid using the ones from the
application module that also bring in a dependency on the internet module.

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 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.
Bugs fixed

- new TCP Westwood and Westwood+ models
- new FdNetDevice model and associated helpers. The FdNetDevice is able
to read and write from a file descriptor. Various helpers are provided
to associate this descriptor with underlying devices or sockets on the
host operating system, including a packet socket for emulation, and
tap devices including a version specialized for use on PlanetLab.
- ns-3-click: it's now possible to (i) have Click pull random numbers from
ns-3 and (ii) have ns-3 set "defines" in Click via the simulation file
(see src/click/examples/nsclick-defines.cc).
- Waf shipped with ns-3 has been upgraded to version 1.7.10 and custom
pkg-config generator has been replaced by Waf's builtin tool.
- create-module.py script has been updated to work with waf 1.7 and support
for creating modules with names containing dashes has been added.
- the M5 release of the LTE module by the LENA project has been
merged; please see src/lte/RELEASE_NOTES for more detailed info

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
- 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
-------------------------
- 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).

ns-3.14 release.
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
- Ubuntu 11.10 (32 bit) with g++-4.6.1
- Ubuntu 10.04.4 LTS (64 bit) with g++-4.4.3
- OS X Lion 10.7.4 with g++-4.2.1
- OS X Snow Leopard 10.6.8 with g++-4.2.1
- 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.
