Simone, You can place your antenna profile manifest file and your antenna profiles anywhere you would like on your system. I would recommend against writing to /usr/share/emane that is a system location which contains dtds and some sample XML. Typically we place our XML in a directory structure that corresponds with the experiments we are performing.
All you need to do is set the 'antennaprofilemanifesturi' parameter (user manual section 7.2.12) to the absolute file name of your manifest file. The contents of your manifest file should contain 'antennapatternuri' attributes that should be set to the absolute file name of your antenna patterns. Any manifest, profile or blockage file that you find in /usr/share/emane/antennaprofiles are there for illustrative purposes only. You do not need to define an antenna profile for an omni. You can configure your omni NEM to use a fixed antenna gain using the 'antennagain' parameter (section 7.2.2), set the 'antennaprofileenable' parameter to 'off', and set the 'antennaprofilemanifesturi' parameter to the absolute file name of your manifest file: NEM using Omni == antennagain=<GAIN or 0> antennaprofileenable=off antennaprofilemanifesturi=/absolute/path/to/your/manifest/file.xml The 'antennaprofilemanifesturi' is required since the omni NEM will be receiving traffic from an NEM using an antenna profile. The NEM using the directional antenna will set 'antennaprofileenable' to 'on', set 'antennaprofilemanifesturi' to the absolute file name of your manifest file, set 'antennaprofileid' to the appropriate profile and set the antenna pointing information using 'antennaazimuth' and 'antennaelevation': NEM using Antenna Profile == antennaprofileenable=on antennaprofilemanifesturi=/absolute/path/to/your/manifest/file.xml antennaprofileid=<PROFILE ID> antennaazimuth=<AZIMUTH DEGREES> antennaelevation=<ELEVATION DEGREES> Antenna patterns are difficult to create unless you are familiar with radiation patterns: https://en.wikipedia.org/wiki/Omnidirectional_antenna https://en.wikipedia.org/wiki/Radiation_pattern -- Steven Galgano Adjacent Link LLC www.adjacentlink.com On 06/06/2013 06:06 PM, smlabs wrote: > Hello, > > I understood the following steps. > I added also some questions where is not clear. > > 1) do I have to create a new folder in "/usr/share/emane" named "antenna > profile" as specified in in Listing 7.1? > I'm asking because I found in "/usr/share/emane/models/universal/xml" > antenna patterns and profiles.
