- 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 reference traces in the ns-3.x-ref-traces directory. In most cases, the example programs whose traces were included in ns-3.x-ref-traces have a corresponding test called from the test.py program. It is still possible to write trace-based regression tests but they are now called from the test.py program.
- New BulkSendApplication sends data as fast as possible up to MaxBytes or unlimited if MaxBytes is zero. Think OnOff, but without the “off” and without the variable data rate. This application only works with SOCK_STREAM and SOCK_SEQPACKET sockets, for example TCP sockets and not UDP sockets.
- Extensions to the energy models: 1) a new Rakhmatov Vrudhula non-linear battery model, 2) additional support for modeling energy consumption in WiFi devices, 3) an example for how to add energy models to a WiFi-based simulation (in examples/energy/ directory).
- New methods to print IPv4 routing tables to an output stream.
- A replacement implementation for TCP for IPv4. TcpSocketBase now replaces TcpSocketImpl. There are subclasses defined for TCP Tahoe, Reno, NewReno, and the original RFC793 without congestion control.
- Energy support for UAN module and Li-Ion energy model. Now each network node can have an associated energy source from which it consumes energy. The user can specify a custom energy model for the underwater transducer, with default values set for WHOI acoustic transducer. Li-Ion battery model added into energy models folder.
- Destination-Sequenced Distance Vector (DSDV) routing protocol is a proactive, table-driven routing protocol for MANETs developed by Charles E. Perkins and Pravin Bhagwat in 1994. This implementation is for IPv4 routing and was contributed by ResilNets Research Group.
- A novel model to simulate LTE networks has been added. It focuses mainly on modeling the E-UTRA part of the system, with a particular attention on the aspects related to the channel, PHY and MAC layers. The most important features available at this moment are (i) a basic implementation of both the UE and the eNB devices, (ii) RRC and entities for both the UE and the eNB, (iii) an Adaptive Modulation and Coding (AMC) scheme for the downlink, (iv) the management of the data radio bearers (with their QoS parameters), the MAC queues and the RLC instances, (v) Channel Quality Indicator (CQI) management, (vi) support for both uplink and downlik packet scheduling, (vii) a PHY layer model with Resource Block level granularity, and (viii) a channel model with the outdoor E-UTRAN propagation loss model.
- Project documentation has been converted from GNU Texinfo to Sphinx.
