1.2 COMPUTER AND INFORMATION SCIENCE
A description of ongoing work which aims to provide better quality propagation models for use in network simulators is provided in this paper. A 3D ray-tracing model is described which allows for accurate specification of a variety of wave scattering phenomena. Details of its parallelisation are given as well as a discussion of future work including the incorporation of a visibility algorithm. Results illustrate the increased realism obtained by using site-specific propagation models.
