Update to version 2.35
ns-2.35 Released on Nov 4, 2011
* Provide fixes to the Tmix traffic generator, mainly to the one-way
TCP implementation, but some changes to the Full-TCP version as well.
Tmix with one-way TCP now performs comparably to Tmix with Full-TCP (albeit
with longer running times and higher memory consumption). Includes
contributions from David Hayes and DongXia Xu at Swinburne and relevant
updates to the documentation and tests.
* Add Marcello Caleffi's Multi-path Dynamic Address RouTing (M-DART)
protocol.
* Add Sidney Doria's Datagram Congestion Control Protocol (DCCP)
implementation.
* Added the SYN_immediate_ack flag so that a DelAckSink agent will
immediately ACK the first (SYN) packet sent by a TcpAgent. The patch contains
changes to tcp-sink.{cc,h}, ns-default.tcl, and affected validation tests.
All validation tests that use the syn_ in TcpAgent were set to
SYN_immediate_ack=false except for the delayed test in test-suite-simple.tcl.
* During long simulations (30-60 minutes), ns would sometimes abort with the
message "TcpAgent: negative RTO!". The problem was that TcpAgent::t_backoff_
was overflowing and becoming negative, since it was doubled each time a
backoff was triggered but maxrto_ prevented the time between doublings from
growing beyond 60 seconds.
* This patch adds support for using one-way TcpAgents with the Tmix traffic
generator, which previously only worked with FullTcp agents.
* Protocol for Unified Multicasting Through Announcements (PUMA)
has been added. PUMA is a distributed, receiver initiated, mesh based
multicast routing protocol.
* A new SCTP patch from Nasif Ekiz and the University of Delaware team.
* added support for Non-Renegable Selective Acknowledgements (NR-SACK).
To enable NR-SACKs, set useNonRenegSacks_ tcl bindable variable to 1 at
both the data sender and the data receiver.
* Concurrent Multipath Transfer with Potentially Failed(CMT-PF) extension
is default now. To use CMT, set useCmtPF tcl bindable variable to 0
at the data sender.
* added new feature to support a limited size send buffer at the data
receiver. Send buffer size can be specified by setting initialSwnd_ tcl
bindable variable to desired value. By default, the variable is set to
0 which means there is no constraint on the send buffer.
* congestion window (cwnd) updates are now done as specified at Section 7.2.1,
7.2.2 and 7.2.3 of RFC4960. Also the number of missing reports to trigger
fast retransmits is reduced to three as specified in RFC4960.
* bug fix. A bug discovered by Eduardo Ribeiro and Igor Gavriloff regarding
to memory deallocation is fixed.
* new validation tests for NR-SACKs and limited send buffer size are added to
the test suite.
ns-2.34 Released on June 17, 2009
* bugfix for 802.11Ext model (from Felix-Schmidt-Eisenlohr and team)
* mac/wirelessPhyExt:
* the power monitor class is responsible to continously track the sum of all
reception power values of all frames arriving in parallel and of the noise
floor. In the earlier implementation this cumulated power was only decreased
in situations where no packet arrived. Otherwise, powers were always further
summed up, leading to a wrong setting of this variable, and in consequence,
a wrong behavior of physical packet reception calculations. Furthermore, the
busy/idle signalling was not correct.
* Add AOMDV (On-demand Multipath Distance Vector Routing in Ad Hoc Networks)
implementation from Marcello Caleffi
* Collection of bug fixes for 802.11Ext model (from Felix-Schmidt-Eisenlohr
and team)
* mac/mac-802.11Ext:
* feedback to higher layers on transmission failure: xmit_failure_data_ is
delivered when a unicast packet was finally not sent successfully- corrected
NAV update: in case a NAV is active and a new NAV is advertised an updated
only occurs in case the new NAV takes longer than the one already running
- bugfix: corrected backoff handling when 0 backoff slots are selected:-
bugfix: resolved memory leak on broadcast packet transmission- duplicate
suppression support: reactivate the feature of duplicate detection on MAC
layer as it was done in earlier versions
* code cleanup: removed TxTimer_t class
* bugfix: ACK frames: explicitly set basic modulation scheme
* mac/wirelessPhyExt:
* update of modulation table: new threshold values are taken for the different
modulation schemes due to newer measurements
* bugfix: resched() instead of sched() in PowerMonitor::expire()
* code cleanup: removed friend class PowerTimer
* code cleanup: updated comment in recordPowerLevel()
* new implementation of PowerMonitor (PowerTimer class now obsolete)
* clarification of CSThresh variable (see below)
* mac/channel.cc: for wirelessPhyExt only: correct calculation of distCST,
using PowerMonitorThresh_ as the critical borderline power and including
antenna gains.
* tools/ranvar.cc: - bugfix: resolved memory leak in Erlang distribution
* Bug fixes for 802.11 infrastructure code, posted by Ilango Purushothaman.
* Patches for better memory management - use standard C++ lists to maintain AP
and client tables, memory leaks fixed in AP scheduling queue
* Triggering of handoff in Ad-hoc mode - Bug reported by Mayur - Resolved by
adding an if condition for checking the 802.11 mode.
* Note: The following traces changed as a result of this, but were verified
by Ilango: ./test-all-wireless-infra ./test-all-wireless-infra-mobility
./test-all-wireless-shadowing ./test-all-wireless-lan-aodv
./test-all-wireless-gridkeeper ./test-all-wireless-lan-newnode
* Import Tmix synthetic Internet traffic generation tool
* Disable string literal warning for gcc version > 4.2

Update ns to 2.27 and take maintainership.
Changes:
- Changed list-based improvement to allow changing of
channels. Previously only a single (static) list of nodes
maintained. Now list of nodes maintained for each channel. Maybe
extended for mobilenodes with multiple netif (talking to multiple
channels) once the multiple netif support is in place.
- Added validation test-suite for RNG in ns.
- Added modified version of setdest from U. of Michigan. Also added an
argument to setdest API that defines the version of setdest being
used.
- Change the name of dumbPolicy to nullPolicy for consistency with
diffserv documentations (suggested by Alexander Sayenko
<sayenko@cc.jyu.fi>)
- Added list-based improvement to ns-2. Code contributed by Valerie
Naoumuv (naoumov@inf.ethz.ch). The improvement involves maintaining
a doubly-linked list to organise mobilenodes based on their
X-coordinates. When sending a packet only those neighbor nodes are
considered who are within a circle corresponding to the
carrier-sense threshold energy level, below which a node cannot hear
the packet. Improvement on original version where all nodes in
topology is considered. considerable gain in run-time performance-
goes down by about 4 to 20 times, depending on the size of the
topology. The larger the topology and greater the no of nodes,
greater the improvement seen with the list-based implementation. Pl
see relevant papaer "simulation of large adhoc networks", appeared
at MSWiM'03, san diego, USA for details.
- Added script <color-event.pl> that takes event/color pairs and
colors pkts in nam output files in order to highlight nam events.
- Modified ns to build with tcl/tk8.4 and new otcl/tclcl (release
pending).
- Diffusion documentation added to ns-manual.
- Diffusion changes made includes (1)Added tcl example scripts for 2
phase-pull, push, 1 phase-pull and gear (with push and 2pp)
scenarios. For gear and other node-position dependent routing in
diffusion, need to have a callback to update node positions. since
the routing filter (like gear) is init'ed before node positions are
assigned gear doesn't get the correct node positions, hence the
callback is required. callback would also be reqd to support node
movements in diffusion in future. For now start gear filters (in
tcl scripts) after node positions are assigned to nodes. This will
go away once callbacks are implemented. (2)Added fix suggested by
Andreas Koepke <koepke@ee.tu-berlin.de> for overflow problem in
lib/main/tools.cc
- Added worm model to support simulations of Internet worm attacks.
This model supports different abstract levels in simulations. It
simulates a detailed sub-network at packet level, and the rest of
the Internet with an analytical model (SIR). It supports two worm
scanning behaviors: random and local-preferred.
- Added event tracing function for simple-mac and 802.11. It was
contributed by <a href="mailto:singal@nunki.usc.edu">Sushmita</a> to
support wireless animations.
- Added directory for nam animations under ns/tcl/edu. Each
subdirecotry contains on animation, including short description,
simulation script, trace file, and nam trace. These animations are
ready to use in classroom. The current three animations are
contributed by Sushmita <singal@nunki.usc.edu> as the outcome of her
directed research project.
- Integrated support for infrastructure mode in 802.11 MAC. The code
was was written by Mike Moreton
- Fixed bug (reported by Fred Stann) in diffusion3 that caused
overflow while reading time ( > 2147 sec).
- New module Delayer for introducing delay variation and channel
allocation delay. This is useful for modeling the effects of
wireless links. Validation tests in "./test-all-links". Code
contributed by Andrei Gurtov.
- Ported SCTP into ns-2. It was actually ported into ns-2.26 by
Armando L. Caro Jr. <acaro@@cis.udel.edu> and his group at PEL, Univ
of delaware. The implementation includes a test-suite-sctp and doc
for sctp (see chapter on SCTP in ns-manual).
- Added APIs for diffusion filters to node-config command. See
tcl/ex/diffusion3 for examples. Also changed UIDs in common pkt
hdr. It now reflects pkt_num_ as in diffusion message hdr.
- Adding ts_resetRTO_ to TCP to control whether or not a
timestamp-enabled sender unbacks a backed-off RTO after making a
valid RTT measurement from an acknowledged, retransmitted packet.
Validation tests are in "./test-all-tcpOptions" in "tcl/test":
"./test-all-tcpOptions timeouts_sack2" (with ts_resetRTO_ true)
"./test-all-tcpOptions timeouts_sack3" (with ts_resetRTO_ false).
The suggestion and initial code for this change are from Andrei
Gurtov. Also adding exitFastRetrans_ to TCP, to fix a problem
with clean exits from Fast Recovery. Set to false for the old buggy
behavior, or set to true for the new good behavior. The default is
true. "./test-all-tcpOptions timeouts_reno_noexitFR" shows the old
behavior, and: "./test-all-tcpOptions timeouts_reno" shows the fixed
new behavior. The problem was that data was sent in response to dup
acks even after Fast Recovery was over. From a bug report by Andrei
Gurtov.
- Improved portability for C++ namespaces
(required for gcc-3.2 where the standard C++ libraries like iostream
are in namespace stl only).
- Added trace support for smac. The "mactype" info stored in
simulator is used to trace data as well as mac pkts (smac or
802.11).
- Ported diffusion3.2.0 into ns. A lot of changes: all applications
re-categorized under gear, ping and rmst. Filters have a separate
dir. gradient now replaced with one-and two-phase-pull-filter under
filter_core.
- Changed the defaults for Agent/TCP/Newreno's newreno_changes1_ and
partial_window_deflation_ to "1", to reflect RFC 2582.
- Adding avoidReordering_ to DelayLink, set to true to avoid
reordering when changing link bandwidth or delay. The code was
contributed by Andrei Gurtov, and the validation test is in
./test-all-links in the directory tcl/test. The default is for
avoidReordering_ to be false, for no change in past behavior.

Update to version 2.35
ns-2.35 Released on Nov 4, 2011
* Provide fixes to the Tmix traffic generator, mainly to the one-way
TCP implementation, but some changes to the Full-TCP version as well.
Tmix with one-way TCP now performs comparably to Tmix with Full-TCP (albeit
with longer running times and higher memory consumption). Includes
contributions from David Hayes and DongXia Xu at Swinburne and relevant
updates to the documentation and tests.
* Add Marcello Caleffi's Multi-path Dynamic Address RouTing (M-DART)
protocol.
* Add Sidney Doria's Datagram Congestion Control Protocol (DCCP)
implementation.
* Added the SYN_immediate_ack flag so that a DelAckSink agent will
immediately ACK the first (SYN) packet sent by a TcpAgent. The patch contains
changes to tcp-sink.{cc,h}, ns-default.tcl, and affected validation tests.
All validation tests that use the syn_ in TcpAgent were set to
SYN_immediate_ack=false except for the delayed test in test-suite-simple.tcl.
* During long simulations (30-60 minutes), ns would sometimes abort with the
message "TcpAgent: negative RTO!". The problem was that TcpAgent::t_backoff_
was overflowing and becoming negative, since it was doubled each time a
backoff was triggered but maxrto_ prevented the time between doublings from
growing beyond 60 seconds.
* This patch adds support for using one-way TcpAgents with the Tmix traffic
generator, which previously only worked with FullTcp agents.
* Protocol for Unified Multicasting Through Announcements (PUMA)
has been added. PUMA is a distributed, receiver initiated, mesh based
multicast routing protocol.
* A new SCTP patch from Nasif Ekiz and the University of Delaware team.
* added support for Non-Renegable Selective Acknowledgements (NR-SACK).
To enable NR-SACKs, set useNonRenegSacks_ tcl bindable variable to 1 at
both the data sender and the data receiver.
* Concurrent Multipath Transfer with Potentially Failed(CMT-PF) extension
is default now. To use CMT, set useCmtPF tcl bindable variable to 0
at the data sender.
* added new feature to support a limited size send buffer at the data
receiver. Send buffer size can be specified by setting initialSwnd_ tcl
bindable variable to desired value. By default, the variable is set to
0 which means there is no constraint on the send buffer.
* congestion window (cwnd) updates are now done as specified at Section 7.2.1,
7.2.2 and 7.2.3 of RFC4960. Also the number of missing reports to trigger
fast retransmits is reduced to three as specified in RFC4960.
* bug fix. A bug discovered by Eduardo Ribeiro and Igor Gavriloff regarding
to memory deallocation is fixed.
* new validation tests for NR-SACKs and limited send buffer size are added to
the test suite.
ns-2.34 Released on June 17, 2009
* bugfix for 802.11Ext model (from Felix-Schmidt-Eisenlohr and team)
* mac/wirelessPhyExt:
* the power monitor class is responsible to continously track the sum of all
reception power values of all frames arriving in parallel and of the noise
floor. In the earlier implementation this cumulated power was only decreased
in situations where no packet arrived. Otherwise, powers were always further
summed up, leading to a wrong setting of this variable, and in consequence,
a wrong behavior of physical packet reception calculations. Furthermore, the
busy/idle signalling was not correct.
* Add AOMDV (On-demand Multipath Distance Vector Routing in Ad Hoc Networks)
implementation from Marcello Caleffi
* Collection of bug fixes for 802.11Ext model (from Felix-Schmidt-Eisenlohr
and team)
* mac/mac-802.11Ext:
* feedback to higher layers on transmission failure: xmit_failure_data_ is
delivered when a unicast packet was finally not sent successfully- corrected
NAV update: in case a NAV is active and a new NAV is advertised an updated
only occurs in case the new NAV takes longer than the one already running
- bugfix: corrected backoff handling when 0 backoff slots are selected:-
bugfix: resolved memory leak on broadcast packet transmission- duplicate
suppression support: reactivate the feature of duplicate detection on MAC
layer as it was done in earlier versions
* code cleanup: removed TxTimer_t class
* bugfix: ACK frames: explicitly set basic modulation scheme
* mac/wirelessPhyExt:
* update of modulation table: new threshold values are taken for the different
modulation schemes due to newer measurements
* bugfix: resched() instead of sched() in PowerMonitor::expire()
* code cleanup: removed friend class PowerTimer
* code cleanup: updated comment in recordPowerLevel()
* new implementation of PowerMonitor (PowerTimer class now obsolete)
* clarification of CSThresh variable (see below)
* mac/channel.cc: for wirelessPhyExt only: correct calculation of distCST,
using PowerMonitorThresh_ as the critical borderline power and including
antenna gains.
* tools/ranvar.cc: - bugfix: resolved memory leak in Erlang distribution
* Bug fixes for 802.11 infrastructure code, posted by Ilango Purushothaman.
* Patches for better memory management - use standard C++ lists to maintain AP
and client tables, memory leaks fixed in AP scheduling queue
* Triggering of handoff in Ad-hoc mode - Bug reported by Mayur - Resolved by
adding an if condition for checking the 802.11 mode.
* Note: The following traces changed as a result of this, but were verified
by Ilango: ./test-all-wireless-infra ./test-all-wireless-infra-mobility
./test-all-wireless-shadowing ./test-all-wireless-lan-aodv
./test-all-wireless-gridkeeper ./test-all-wireless-lan-newnode
* Import Tmix synthetic Internet traffic generation tool
* Disable string literal warning for gcc version > 4.2
