NEW:

• Added a new module to model an "internet cloud". The component can be configured to model packet delay, datarate and drop probability between each input-output interface pair. The parameter matrix is provided as an XML configuration file. See the README file in src/nodes/internetcloud for further details.
• New SimpleVoIPReceiver/Sender applications that gather MOS (Mean Opinion Score) for measuring voice quality.
• Added HNA support to the Batman protocol (MANET)

CHANGED:

Applications:

• PingApp: Shows the configured destination address at the end of the simulation.
• TCPBasicClientApp: bugfix #611: simulation generated an ASSERT if numRequestsPerSession parameter value larger than 1.
• TcpApp: socket state is now shown on the GUI (in Echo, Sink and Session apps.)
• VoipTool: was renamed to VoIPStream (The actual module names are VoIPStreamSender/Receiver.)
  
  

Ethernet:

• Transmission channel's 'disabled' parameter is now correctly handled in EtherMacBase.

Ieee80211Mac:

• Better parameter processing in MAC: error is thrown if an undefined value is specified for the opmode or autoBitrate parameters.
• Added the Ieee80211Descriptor class to assign modulation speed and type for the different opModes.
• Bugfix: Default bitrate for opMode 'p' was incorrectly set.

BGP:

• Minor optimizations
• Bugfix: The text in specification "sets the ConnectRetryTimer to zero" means: restart this timer. The _connectRetryTime member now stores the timeout value.

Manetrouting:

• updated documentation
• replaced Uint128 with ManetNetworkAddress
• removed:
  • unused ManetTimer and BatmanTimer class
  • unused static variables
  • isIpLocalAddress(), uses isLocalAddress()
  • convertAddressToString()
  • getXPos(), getYPos() functions, you should use getPosition() instead.
• redesigned coordinate and speed storage and access. replaced double x,y with a Coord. getDirection() now returns the speed vector (as a Coord)
• getters returns UNSPECIFIED_ADDRESS if addrType==UNDEFINED
• merged sendToIp() code into a common base function sendToIpOnIface()

AODV:

• AODV's hand-written descriptors were replaced with generated ones.
• aodv_msg_struct.h: added getter methods expected by the generated descriptors removed hand-written aodv_msg_struct_descriptor.cc

Batman:

• Updated and expanded documentation
• Updated the code to match the latest available "batmand" version.
• Numerous optimizations
• Fixed several memory leaks
• Fixed routing table corruption and possible crash when multiple radios were used in a single host
• Fixed decapsulation of incoming packets. Now it checks for the type of decapsulated packet.
• Fix for a problem when aggregated batman packets were dropped erronously.
• Added HNA support. Nodes can advertise external networks, so traffic towards those networks can be routed correctly. Use the announcedNetworks parameter to specify multiple connected external networks.
• Added SourceModifier script to help the conversion from the original batmand code.
  • fixes spaces, tabs and empty lines
  • replaces some c-style structs to c++-style classes
  • replaces some batmand specified list manipulators with c++ code
  • replaces malloc/free with new/delete
  • removes prof_start()/prof_stop() calls

Examples:

• Added a new simulation with wired and wireless hosts exchanging UDP data via an AccessPoint. It shows how to use the IPv4NetworkConfigurator to mix wired and wireless networks.
• Fixes for BGP examples.
• New example to demonstrate HNA support in Batman.
• Hostautoconf examample moved to the adhoc folder.

Other changes:

• Uint128 class was removed. Use ManetNetworkAddress class instead.
• Visual changes in StandardHost/NodeBase: utility module icons are now smaller and wlan[]/PingApp[] modules are displayed in a row.
• NodeBase: it is possible to use mobility module even if numRadios = 0
• Added check for detecting too small netmask parameter value in HostAutoConfigurator
• PacketDump: TCP header option fix (dumped only in verbose mode.)
• Bugfix #620. The module pointer returned by a ModuleAccess class is now cached only if get() was used. For get(module) no caching is done.
• MACAddress: made the constructor explicit so we will not see unexpected implicit conversions in future
• IPv6Address: removed Uint128 related functions and added an additional constructMask() method
• headerserializers: compile fix for Visual C++ 10.0 and later
• Pcap now records on ALL interfaces by default (including external IFs). Added Enter_Method for better error reporting if a packet cannot be serialized. Also added an icon for PcapRecorder.
• Several TCP related fixes.
