Open problems
- How to deal with
scattering from vegetation
- How to deal with dynamic scenes (moving cars, etc )
- Deal with larger scenes. (WISE began to run out of steam
for models of large cities with 2-3 diffractions, and 5-10 reflections)
- Do predictions faster, possibly real-time
- Make more accurate predictions.
- Predict Interference
- Correctly model Antenna Patterns (not omnidirectional)
- Inverse Ray Tracing (determine transmitter location, given a set
of received signals)
- Determine best position for a UAV to provide coverage to multiple
soldiers in an urban environment.
