MiXiM Changelog

What's new in MiXiM 2.3

Mar 6, 2013
  • More work on getting better INET compatibility, now we are very close to integrate MiXiM into INET framework. (Many thanks to Rudolf Hornig)
  • Added type definition for the radioStateAttenuation collection, changed some return value definition to const ref. Using the MapUtils::incNextPosition method for calculating nextPosition. (Instead of adding ONE to calculating the nextPosition, we use the MapUtils::post operation now).
  • The default value for the constraint area is now derived from the playgroundSize parameter.
  • Some compiler fixes for gcc >= 4.7. nic.phy.sensitivity MiximRadio, BatteryAccess>MiximBatteryAccess , ChannelAccess>ConnectionManagerAccess
  • Some MacLayer adjustments to use common MiXiM layer concepts
  • Some Bugfixes

New in MiXiM 2.2.1 (Dec 15, 2011)

  • .cproject is now OMNeT++ 4.2 conform
  • renamed mobility coordinates from (x, y, z) into (initialX, initialY, initialZ) and
  • added meter-unit for it (as in INET)
  • constraintAreaMin[XYZ] and constraintAreaMax[XYZ] for mobility modules to specify
  • a specific random generation area for nodes (will be adjusted to playground area)
  • adjusted the example scripts and .anf files for WSNRouting, ieee80215a, and
  • ieee80215Narrow
  • fixed MoBAN emit/subscribe scope for position updates
  • small fix for SimpleBattery empty battery test
  • getAnalogueModelFromName() is now a const method
  • fixed typename-error for GCC

New in MiXiM 2.2 (Nov 21, 2011)

  • It is mainly a maintenance release whith focus on INET integration.
  • adjusted the OMNeT++ 4.2 API changes
  • modified deciders filterSignal method, parameters now are AirFrame pointer and the senders and receivers positions
  • completly removed BaseUtility and Blackboard; MiXiM uses now the OMNNeT++ signaling handling (registerSignal, subscribe, emit, ...)
  • receiveBBItem(...) methods should be replaced by receiveSignal(...).
  • Introduced new 2 types for MACAddress and NetwAddress, see SimpleAddress.h
  • This should solve some problems with inproper handling of same address type for different layers.
  • Added some value tests for infinity in mapping interpolation. (David Eckhoff)
  • Merge thermalNoise into attenuattion map for excluded AirFrame.
  • Ned INic definition was renamed to IWirelessNicUpperCtl (like INET IWirelessNic plus upper control gates)
  • Add sendReply switch to BurstApplLayer, to disable send reply for
  • BROADCAST_MESSAGE's.
  • Renamed introduced timing info methods in Signal ( getSignalLength() ->
  • getDuration(); getSignalStart() -> getReceptionStart(); getSignalStart() +
  • getSignalLength() -> getReceptionEnd() )
  • Signal now contains infos about the sending/receiption module/gate (getSendingModule;
  • getReceiptionModule). The info will be extracted/saved from AirFrame in BasePhyLayer at receiving.
  • Changed [Lower/Upper]Gate to [Lower/Upper]Layer.
  • handleAirFrame method gots an AirFrame as parameter, instead of cMessage.
  • renamed BasePhyLayer::sendControlMsg to BasePhyLayer::sendControlMsgToMac
  • refactored the NED files to simplify the usage and to make it more generic
