Physics-Based Wireless Channel Propagation Models: Fundamental advances and integration with network protocol design

March 26, 2019 @ 2:00 pm - 3:30 pm

Co-sponsored by: Polygrames, STARaCom, IEEE section Montréal

Transforming metropolitan areas into “smart” cities requires the large-scale deployment of enabling information and communication technologies. From smart-grid monitoring to wireless control of mass transit systems, point of care and public safety applications, these technologies are based on geographically distributed wireless access points.
The financial feasibility of installing and maintaining such networks of access points, meeting standards for “green” (energy efficient) and safe (in terms of radiation exposure of the population) operation, depends on the availability of computational planning tools.
This talk will present recent research on computational electromagnetic techniques formulated to address some of these challenges.
– A hybrid technique, combining vector parabolic equation (VPE) and ray-tracing methods, which can model wireless propagation across entire railway networks, reserving the ray-tracer for complex station geometries, while applying the VPE method to long tunnel sections. Validation data have been provided by a 2.4 GHz measurement campaign in the rugged, complex environment of the London (UK) underground -one of the largest and most successful validation studies ever reported in the relevant literature.
– The integration of physics-based propagation models with network protocol design. For decades, these two areas have evolved as orthogonal areas in communication systems research. This fragmented approach does not exploit available efficiencies when planning and deploying communication systems. In an attempt to integrate the two areas, we harness the understanding of the underlying physics of electromagnetic propagation to enhance the robustness of network protocol design by deriving physics-based network-level performance metrics. To that end, we have recently integrated propagation models for tunnels with network protocol design for train communication systems, demonstrating the importance of accurately accounting for the physics of radio wave propagation to optimize the performance of wireless networks for train control. Such an integration will become even more important with the proliferation of wireless services and the emergence of 5G systems.
