How can I determine my position by triangulation on known routers?

Question

Is there any open source software available? Basically, I just want to triangulate based on signal strength of routers whose location is fixed and known.

I realize there can be cases of interference, but let's just stick to listing known source code. Thanks.

Answer 1

I don't know of any trilateration software... someone should write an open source library.

Take a look at the trilateration formulas. They shouldn't be difficult to implement. The hard thing to do will be to put your points and the router points onto a grid, and the measurements you have for the locations of your routers should inform your decision on how to do that. Once you've mapped everything onto a grid, the formulas aren't complicated and shouldn't be difficult to figure out.
