A graph based mobility model

[RBM-IT]

Hello everyone,

I want to assign to my nodes in ns-3 a graph based mobility model. 

I want to extract an area from a map (OpenStreetmap), generate a graph of (nodes(intersections) and edges(ways)), then generate mobility of nodes (people) moving on this graph.

I found works on this with SUMO but for Vehicles and not pedestrians.

I want to know if there is any mobility model in ns-3 that get closer to such scenario or i should generate this on my own?

Is there any mobility generator that facilitate this mission (bonnmotion ?) since my work is about an algorithm of scheduling and mobility models is just my input for my nodes.

Any recommandations are welcome :)

Thank you

Hi

Are you sure that pedestrians can not be simulated with SUMO, because from their website I get this:

Microscopic simulation - vehicles, pedestrians and public transport are modeled explicitly

For some reason their website is not working properly and redirects to a generic DLR page.

Try this cached version

Hi Kostantinos,

I looked on this before, but no clear tutorial. I even installed SUMO, this pedestrian feature is a new feature and nothing clear about it.

I will try to look more on it.

any other suggestions?

The most simple "street" model in Bonnmotion is the Manhattan model, where the map is a set of squares.

I'm not sure if the "Random Street" or the "Map-based Self-similar Least Action Walk" model lets you load a preconfigured map.

Hello Martin,

All of those models doesn't give the option to load a new map , they work on a predefined one.

I want to make my scenario as real as possible by using real map, the generate synthetic mobility traces on it.

Perhaps the WayPoint model in NS-3 could be useful.

You can create the waypoints from the nodes you have and define their order according to the edges you have.

Depending on the size of your scenario and nodes, this could potentially be time-consuming, but not unfeasible.

Thanks for your answers,

But i really want to do a real map based mobility.

SUMO has a problem with its website.. 

I don't want to lose a lot of time doing all the steps (loading OSM map, adding new model to bonnmotion then generating the trace to be used in my ns-3 simulation..))

Any further suggestions are welcomed, i will keep the issue as open..

regards
