The Matlab model allows the evaluation of WiFi performance. It is based on the work by Baras et al. for multihop ad hoc networks (https://ieeexplore.ieee.org/document/4586081).
The other model is written in C and estimates the performance of reliable transport over a multihop network. It is based on the DTSN protocol developed by Marchi et al. (https://ieeexplore.ieee.org/document/4381601).
