Layered Mobility Model Architecture

LEMMA is a mobility simulator based on the theoretical framework with the same name. The theoretical framework is described in this paper. The mobility simulator is discussed in details in our upcoming paper at CNS 09 - "Creating advanced mobility models with LEMMA".

Please, report any problems you may encounter. Do not hesitate to ask directly your questions. See the README file. You can browse the code here or get it via SVN:
svn checkout https://svnet.u-strasbg.fr/lemma/trunk lemma

Afterwards, you can run the example scenarios from lemma directory:
python2.5 src/scenarios/scenario_runner.py


The supported parameter are:

-h or --help	Display the help page.
-s or --scenario	Specify the scenario to execute. Possible scenarios are 1-12. Default is 1.
-n or --nodes	Specify the number of nodes to simulate. Defaults is 10.
-d or --duration	Specify the simulated time duration (in seconds). Default is 1000.
-o or --output	Where to output the resulting traces. Possible values are a directory or the standard output ("-"). Default is -.
-f or --format	Format of the output. Possible values are csv and ns2. Default is csv.
-m or --more-data	Output more (debug) information. This will cause some additional, layer-decision related information to be written to the output.
-v or --visualize	Enable 3D visualization module.
-j or --jsonrpc-server	Address or name of host to which to send mobility information via JSON-RPC. If not set, the JSON-RPC functionality is not used.
-p or --port	Port of JSON-RPC server.

Installation
You can install it with setuptools by simply doing: easy_install https://svnet.u-strasbg.fr/lemma/trunk
Please note, that you should install the VPython package manually.
If for some reason this does not work for you, try installing the following packages manually: In order to run it you have to install Python 2.5, SimPy NetworkX, simplejson (unless you are using Python 2.6 or later) and jsonpickle. Running a cooperative simulation requires the installation of ns-3-coop (see here for more information). If you want to try the 3D visualization you also have to add the VPython package.

You can see the development progress via our Trac system here. We are currently looking for an additional, dedicated developer for the system, so expect the development process to accelerate significantly in the comming months.
