TMgen is a tool for generating spatial, temporal, and spatio-temporal traffic matrices. Generation is based on the Max Entropy model described in Spatiotemporal Traffic Matrix Synthesis by Paul Tune and Matthew Roughan, published in ACM SIGCOMM 2015.

Other, simple models (e.g., uniform, gravity) are also implemented for convenience.

• Random Gravity Model
• Modulated Gravity Model
• Non-stationary Conditionally Independent Model
• Spike Model
• Gravity Model
• Uniform Model

1. Install numpy and cython. (For example using pip install numpy cython)
2. Run pip install .

See http://tmgen.readthedocs.io/ for the docs.

To Paul Tune, Matthew Roughan, and Ari Pakman for their work in this space and for making their code available. This code is an adaptation of their Matlab versions MaxEnt and HMC
