<p> |

ns-3 is an evolving system and there will be API or behavioral changes |
|
17 |
from time to time. Users who try to use scripts or models across |
|
18 |
versions of ns-3 may encounter problems at compile time, run time, or |
|
19 |
may see the simulation output change. </p> |
|
20 |
<p> |
|
21 |
We have adopted the development policy that we are going to try to ease |
|
22 |
the impact of these changes on users by documenting these changes in a |
|
23 |
single place (this file), and not by providing a temporary or permanent |
|
24 |
backward-compatibility software layer. </p> |

The goal is that users who encounter a problem when trying to use older |
34 |
code with newer code should be able to consult this file to find |
|
35 |
guidance as to how to fix the problem. For instance, if a method name |
|
36 |
or signature has changed, it should be stated what the new replacement |
|
37 |
name is. </p> |
|
38 |
<p> |
|
39 |
Note that users who upgrade the simulator across versions, or who work |
|
40 |
directly out of the development tree, may find that simulation output |
|
41 |
changes even when the compilation doesn't break, such as when a |
|
42 |
simulator default value is changed. Therefore, it is good practice for |
|
43 |
_anyone_ using code across multiple ns-3 releases to consult this file, |
|
44 |
as well as the RELEASE_NOTES, to understand what has changed over time. |
|

47 |
This file is a best-effort approach to solving this issue; we will do |
|
48 |
our best but can guarantee that there will be things that fall through |
|
49 |
the cracks, unfortunately. If you, as a user, can suggest improvements |
|
50 |
to this file based on your experience, please contribute a patch or drop |

<li>DSR link layer notification has changed. The model originally used |
192 |
"TxErrHeader" in Ptr<WifiMac> to indicate the transmission |
|
193 |
error of a specific packet in link layer; however, it was not working |
|
194 |
correctly. The model now uses a different path to implement |
|
195 |
the link layer notification mechanism; specifically, looking into the |
|
196 |
trace file to find packet receive events. If the model finds one |
|
197 |
receive event for the data packet, it is used as the indicator for |
|
198 |
successful data delivery.</li> |

<li>In the MobilityHelper class, the functions EnableAscii () and EnableAsciiAll () were changed to use output stream wrappers rather than standard C++ ostreams. The purpose of this change was to make them behave analogously to other helpers in ns-3 that generate ascii traces. Now, the file stream that is open in MobilityHelper is closed nicely upon asserts and program exits.</li> |

<li>Sending a packet through Ipv4RawSocket now supports checksum in the Ipv4Header. It is still not possible to manually put in arbitrary checksum as the checksum is automatically calculated at Ipv4L3Protocol. The user has to enable checksum globally for this to work. Simply calling Ipv4Header::EnableChecksum() for a single Ipv4Header will not work.</li> |

<li> In the spectrum module, the parameters to SpectrumChannel::StartTx () and SpectrumPhy::StartRx () methods are now passed using the new struct SpectrumSignalParameters. This new struct supports inheritance, hence it allows technology-specific PHY implementations to provide technology-specific parameters in SpectrumChannel::StartTx() and SpectrumPhy::StartRx(), while at the same time keeping a set of technology-independent parameters common across all spectrum-enabled PHY implementations (i.e., the duration and the power spectral density which are needed for interference calculation). Additionally, the SpectrumType class has been removed, since now the type of a spectrum signal can be inferred by doing a dynamic cast on SpectrumSignalParameters. See the <A href="http://mailman.isi.edu/pipermail/ns-developers/2011-October/009495.html" >Spectrum API change discussion on ns-developers</A> for the motivation behind this API change. |

<p>Unit test case DoRun() functions no longer return a bool value. Now, they don't return a value at all. The motivation for this change was to disallow users from merely returning "true" from a test case to force an error to be recorded. Instead, test case macros should be used. |

<p>The method InterferenceHelper::CalculateTxDuration (uint32_t size, WifiMode payloadMode, WifiPreamble preamble) has been made static, so that the frame duration depends only on the characteristics of the frame (i.e., the function parameters) and not on the particular standard which is used by the receiving PHY. This makes it now possible to correctly calculate the duration of incoming frames in scenarios in which devices using different PHY configurations coexist in the same channel (e.g., a BSS using short preamble and another BSS using long preamble). </p> |

<p>WifiMode now has a WifiPhyStandard attribute which identifies the standard the WifiMode belongs to. To properly set this attribute when creating a new WifiMode, it is now required to explicitly pass a WifiPhyStandard parameter to all WifiModeFactory::CreateXXXX() methods. The WifiPhyStandard value of an existing WifiMode can be retrieved using the new method WifiMode::GetStandard().</p> |

To accommodate support for the radiotap and prism headers in PCAP traces, the interface for promiscuos mode sniff in the wifi device was changed. The new implementation was heavily inspired by the way the madwifi driver handles monitor mode. A distinction between TX and RX events is introduced, to account for the fact that different information is to be put in the radiotap/prism header (e.g., RSSI and noise make sense only for RX packets). The following are the relevant modifications to the WifiPhy class: |

<li> class NetDevice has added a pure virtual method that |
|
1881 |
must be implemented by all subclasses: |
|
1882 |
<pre> |
|
1883 |
virtual void SetPromiscReceiveCallback (PromiscReceiveCallback cb) = 0; |
|
1884 |
</pre> |
|
1885 |
All NetDevices must support this method, and must call this callback |
|
1886 |
when processing packets in the receive direction (the appropriate place |
|
1887 |
to call this is device-dependent). An approach to stub this out |
|
1888 |
temporarily, if you do not care about immediately enabling this |
|
1889 |
functionality, would be to add this to your device: |
|
1890 |
<pre> |
|
1891 |
void |
|
1892 |
ExampleNetDevice::SetPromiscReceiveCallback |
|
1893 |
(NetDevice::PromiscReceiveCallback cb) |
|
1894 |
{
|
|
1895 |
NS_ASSERT_MSG (false, "No implementation yet for |
|
1896 |
SetPromiscReceiveCallback"); |
|
1897 |
} |
|
1898 |
</pre> |
|
1899 |
To implement this properly, consult the CsmaNetDevice for examples of |
|
1900 |
when the m_promiscRxCallback is called. |
