Changelog

WOSS changelog:

PLEASE NOTE: WOSS is in its development stage, API changes will be limited at minimum, but this cannot be guaranteed.

• v1.0.0
  • release version
• v1.0.1
  • woss::Coord, woss::CoordZ : latitude, longitude and depth are now double value (instead of woss::PDouble)
  • woss::ResPressureTxtDb, woss::ResTimeArrTxtDb : added a space_sampling feature
  • woss::WossDbManager : the managing of custom enviromental data has been reworked, check doxygen documentation and basic_samples
  • WossCbrModule class added
• v.1.1.0
  • World Ocean Atlas 2005 and 2009 SSP Databases : data from WOA2009 has been released; these files are fully compatible with the 2005 version code
  • woss::CustomDataContainer : bugs fixed
  • woss::Location: class for positioning added
  • WossPosition: new class added. WOSS now expect a WossPosition as Miracle Position class

    See also

    basic_samples for usage.

  • WossWpPosition : class has been reworked
  • woss::WossCreatorContainer : class has been added
  • woss::WossCreator, woss::BellhopCreator : interfaces expanded, they now handles custom values for woss::Location objects
  • woss::ACToolboxWoss : bugs fixed
  • woss::BellhopWoss : bugs fixed
  • woss::TimeReference, woss::TimeReferenceTcl : classes for providing WOSS a time reference
  • woss::RandomGenerator, woss::RandomGeneratorTcl : classes for providing WOSS a random numbers generators
  • WossRandomGenerator, WossRandomGeneratorTcl : hooks for NS2 random generators
  • woss::DefHandler : now can set and return a time reference and a random generator objects

    See also

    basic_samples for usage.

  • woss::SSP : class has been updated to work with woss::RandomGenerator
• v.1.2.0
  • woss::RandomGenerator : bug fixed
  • woss::WossManagerResDbMT : some bugs fixed in thread allocation
  • woss::ACToolboxWoss : bug fixed
  • woss::ResTimeArrBinDb, woss::ResTimeArrBinDbCreator, woss::ResPressureBinDb, woss::ResPressureBinDbCreator : classes for storing computed results in a binary file
  • ChannelEstimator, ChannelEstimatorPlugin : now works with MAC address instead of IP address to permit power control at MAC level. This now requires that only the MLL ARP table has to be filled instead of routing tables and ARP tables. Space sampling capability added
  • woss::Transducer : transducer definitions added
  • woss::TransducerHandler : transducer handler definitions added
  • woss::BellhopWoss : addded beam pattern capabilities
  • woss::BellhopCreator : added custom beam pattern capabilities

  • WossPosition, WossWpPosition : added support for dynamic vertical beam pattern orientation
  • UnderwaterMPhyBpsk : some tcl variables RENAMED

    See also

    UnderwaterMPhyBpsk, tcl samples

  • UwMPhyBpskTransducer, WossMPhyBpsk : added support for woss::Transducer, to properly simulate SPL and energy consumption
  • added beam pattern description of BTech, ITC, ITT, RESON transducers

    See also

    beam_pattern_page

  • test_aloha_no_dbs.tcl, test_aloha_with_dbs.tcl : now channel estimation process properly works
  • new tcl sample added

    See also

    samples subdirectory

  • doxygen basic samples page removed, all the comments are inline within the tcl files
  • NOTE: from version 1.2.0, the standard configuration of MIRACLE's MIV interface retrieves multiple arrivals from WOSS and computes interference using a Gaussian model or, equivalently, by summing all taps related to the interferers the same way as in Bellhop's "incoherent mode". In addition, if the interference level varies throughout the duration of a packet, the typically different error rates that result are separately accounted for in the computation of the overall packet error rate. This is the default version now.
    This change has been applied as part of the work for the CLAM project, funded by the European Commission, G.A. 258359.

• v.1.3.0
  • WossChannelModule : channel_eq_time_, channel_eq_snr_threshold_db_ and channel_symbol_time_ introduced, channel_time_resolution_ removed
    • the channel now coherently sums all taps at channel_symbol_resolution_
    • the attenuation threshold in db is calculated from channel_eq_snr_threshold_db_
    • the first tap that has txloss less or equal than the attenuation threshold is found. If the threshold is less than 0 then the threshold is set to 0, and the first tap is taken.
    • then all taps after the above tap + channel_equalization_time_ are incoherently summed if channel_eq_time_ == 0 no eq is done. if channel_eq_time_ < 0 then all taps are incoherently summed
    • all taps after channel_eq_time_ are not processed

  • Altimetry modeling has been introduced:
    • woss::Altimetry is the standard flat altimetry
