The propagation simulator generates realistic propagation for mobile nodes operating in the urban environment. The propagation simulator takes the city map as input and generates a matrix of the propagation characteristics between all pairs of locations. Once the complete propagation matrix is determined, mobility tracefile is used as input and the propagation tracefile is generated. The propagation trace file provides the propagation between node pairs.

Some current features:

• The transmissions and reflections are modeled according to the beamtracing (a variant of raytracing) algorithm.

• The diffraction is modeled according to the uniform theory of diffraction.

• The simulator is capable of estimating key propagation metrics such as channel gain, delay spread, angle of arrivals and departures (for estimating doppler spread and for simulating directional antennae) etc.

• The propagation matrix is calculated for outdoor-outdoor, indoor-indoor, and outdoor-indoor locations.

• The indoor propagation is modeled according to the Attenuation Factor (AF) model.
