- Diffusion 3.2.0
- ---------------
- - Added support for blacklisting neighbor nodes to the Filter API. The
- two new API functions (addToBlacklist() and clearBlacklist()) were added
- to dr.cc and supporting code was added to the filter_core.
- - Added the first alpha version of RMST (Reliable Multi-Segment Transport).
- The sendRmst() API function was added to dr.cc. This filter is located
- in the filters directory and there are sample rmst applications in
- the apps directory.
- - Changed the node id environment variable from scadds_addr
- to node_addr.
- - Added support for emstar-class devices with the --with-emstar
- configure option.
- - Added --disable-stats and --with-emsim options to configure.
- --with-emsim is a super-set of --with-emstar, but also adds
- support running diffusion under emsim. It will try to detect
- if it's being executed under emsim and then get node and
- group ids from the corresponding environment variables. When compiled
- with --with-emsim, Gear will also try to get node location information
- from emsim's SIM_LOC environment variable.
- --disable-stats will remove all iostats code from the filter_core
- (and the two stats-related command-line options -s and -i).
- - Added the DiffPrintWithTime function. It works the same way as
- DiffPrint, but will print a timestamp before the message.
- - Added support for gear to forward messages to geographic points
- (in addition to regions).
- - Changed diffusion so it outputs stats to /tmp/diffusion-%d.out,
- allowing multiple nodes running on a single machine to create
- separate files (removed the ifdef for ns to it will do it also
- inside ns).
- - Changed the directory structure to group diffusion filters and
- applications in separate directories. Also moved stats.cc from the
- library to the filter_core directory.
- - Renamed gradient --> two_phase_pull and diffusion --> filter_core
- to avoid confusion. Some gear files were also renamed to match files
- in other directories.
- - Removed support for the old rpc_stats mechanism (from lib/drivers)
- Diffusion 3.1.3
- ---------------
- - Diffusion now compiles with GCC 3.1 without any warnings.
- - Updated the autoconf/automake scripts to work with autoconf 2.52,
- automake 1.6.3 and libtool 1.4.2. These versions are now required if
- users want to re-create the configure script. make dist now includes
- all other files (CHANGES, VERSION, COPYRIGHT, doc/*, and config/*).
- In addition, the --with-sh4 and --with-ipaq configure options were
- removed (the new autoconf version uses --host for cross-compiling).
- - Changed the sendPacket function in the WINSNG driver to print the
- destination node if it is not cached.
- - Fixed a bug in gradient.cc that caused positive reinforcements to also
- go to local sources.
- - Updated parameters in config.hh to optimize diffusion for the various
- supported radios.
- - Changed the iolog module to also output time information, allowing
- logs to be merged later offline if node's clocks are synchronized
- (this requires users to upgrade to Diffusion Visualization Tools 1.0.1
- as this release will not work with prior versions).
- - Merged a few ns related fixes from the ns distribution.
- - Updated push_sender and push_receiver to work with gear.
- - Added new addTimer function to the diffusion API. Old addTimer still
- works but it is now obsolete and support will be removed in future
- releases. Refer to the updated diffusion API document for more details.
- - Changed the event management functions in diffusion/library. There is
- a new class (TimersManager) that now controls the event queue. Changed
- all applications that use timers (diffusion, gradient, and gear) to
- use the new addTimer API.
- - removeTimer is now supported in ns.
- - Removed all timer references from config.hh in lib/main.
- - Changed gradient.cc not to forward data back to where it comes from.
- This will suppress duplicate traffic when we have a lot of cross
- subscriptions.
- - Improved debugging in Gear. All debug messages now have a timestamp.
- Diffusion 3.1.2
- ---------------
- - Fixed timing issue in dr.cc (ns related issue).
- - Added support for gear to work with push.
- - Added an iohook layer that allows code to work between diffusion core
- and the device drivers.
- - Added support for an iolog layer that logs incoming and outgoing
- packets as they are received/sent to the various device drivers.
- - Removed support for the BBN logger.
- Diffusion 3.1.1
- ---------------
- - Added support for the new Sensoria RF API (Tested with Sensoria
- software version 2.0.1).
- - Changed the filter add/update scheme so diffusion can be
- started after filters.
- Diffusion 3.1
- -------------
- - Revised GEAR to add support for all four operators (GE, GT, LE, LT)
- for declaring a closed geographic region.
- - Added support for PUSH in the library API and in the gradient filter.
- - Added push_sender and push_receiver to the pingapp directory. These
- are the 'push' versions of ping_sender and ping_receiver.
- - Removed agent1/agent2 from the distribution.
- - Changed the log filter to also print the packet size.
- - Included a revised (release 9.0) API document, with examples of
- PUSH and GEAR subscriptions/publications.
- - Diffusion now uses autoconf/automake. It simplifies configuring/
- compiling diffusion for the different hardware platforms and
- rf device options.
- Diffusion 3.0.7
- ---------------
- - Added the first alpha version GEAR in the apps directory. Diffusion
- now should be able to use geographic information to route packets,
- not requiring all interest messages to be flooded.
- - Changed the filter scheme so now each filter has to have a
- distinct priority (i.e. we don't support two filters with the
- same priority value anymore).
- - Merged SendMessage and SendMessageToNext into a single function,
- (SendMessage). It now allows filters to specify the next filter's
- priority and therefore allows filters to be bypassed.
- - Changed the message class not to include a copy of the raw packet
- anymore.
- - Changed all instances of FLAGGED_DATA to EXPLORATORY_DATA, in order
- to be consistent with the names used elsewhere.
- - Added functionality to the API allowing filters work to in a single
- thread mode. Added the doIt() and doOne() API functions to allow
- the application/filter to give up its thread (either permanently
- or just for a moment) for the library API to receive packets and
- manage timers.
- - Added the DiffApp class that applications and filters can derive
- from. It adds basic command line parsing code and keeps some of
- the library's interface code.
- - Fixed a bug in agent1/agent2 when running in multi-threaded mode
- (there's a lock inside libc that blocks fflush when also doing a
- getc).
- - Added the iPaq ARM platform to the supported systems (in config.mk).
- Diffusion 3.0.6
- ---------------
- - Added support for BBN's distributed logger.
- - Changed the diffPrint function to use the variable argument
- list syntax, as suggested by Peter Boettcher.
- - Renamed the agent applications to ping_sender and ping_receiver,
- and added some extra functionality to measure latency and packet
- loss.
- - Included the Steel Knight Applications (sk_sensorApp and
- sk_gatewayApp).
- - Fixed bug when receiving an incoming message from the MoteNIC.
- - Included the nested queries applications in the distribution under
- apps/nested.
- Diffusion 3.0.5
- ---------------
- - Changed several makefiles to ease code integration.
- - Changed diffusion statistics to include total number of messages sent
- to a neighbor (unicast + broadcast).
- - Changed some internal names to allow easier NS integration.
- - Added wrappers for time and output functions to allow distributed
- logging and easier NS integration.
- - Added option to support delayed positive reinforcement messages in
- response to an exploratory data message.
- Diffusion 3.0.4
- ---------------
- - Fixed the code to work when only a single data packet is sent in
- response to an interest message.
- - Added more randomization to the code so it works better when clocks
- are synchronized.
- - The distribution now includes a source routing filter that can be
- used to send a message along a pre-specified path.
- - Tuned diffusion parameters for optimal operation on the SensIT
- hardware.
- Diffusion 3.0.3
- ---------------
- - Diffusion can now use alternate ports (instead of the default 2000)
- with the new command line option '-p port'. Other apps will have to
- be changed to use this feature.
- - The '-s' command line option has been removed.
- - This version features an initial implementation of the device independent
- layer in diffusion along with diffusion drivers for the RPC, the MoteNic
- Wired UDP and UDP communication with local modules/apps. Everything has
- been moved to main/drivers.
- - Diffusion/and the API library now use dynamically allocated buffers for
- both incoming and outgoing packets.
- - Fixed the code to compile without warnings on gcc 2.97 (used to cross
- compile code for the new Sensoria nodes).
- - Fixed all Makefiles to include the config.mk configuration file.
- - The UDP driver now can support diffusion running on port other than
- 2000. The config file for the wired diffusion now accepts the port
- number along with the host ip address. This allows one to run multiple
- 'diffusion nodes' on a single machine.
- - Diffusion now has a driver for the WINSNG 2.0 nodes' radios.
- Diffusion 3.0.2
- ---------------
- - Removed all dependencies from the radiometrix library.
- It should compile fine now with Red Hat 7.1. This version
- of diffusion does not support the old 'userland' implementation
- of the radiometrix drivers.
- Diffusion 3.0.1
- ---------------
- - Initial release of diffusion 3.
