This paper proposes CORNER a low computational cost yet accurate urban propagation prediction technique for ad hoc networks in urban scenarios and provides validation of the model through a side-to-side comparison of real experiments and simulations.Abstract:
Recent advances in portable technologies suggest that ad hoc networks will finally move out from the research and military harbors to the commercial world. In particular, vehicular safety and entertainment applications are mature for the market. Several major manufacturer are considering vehicular communications as an opportunity to increase the profitability and marketability of their vehicles. In this phase, simulations are essential to evaluate the performance of protocols and applications large urban Ad Hoc and Vehicular networks. This paper tackles on the long overdue issue of an high fidelity propagation model for urban ad hoc networks. In particular, we propose CORNER a low computational cost yet accurate urban propagation prediction technique for ad hoc networks in urban scenarios. We also provide validation of the model through a side-to-side comparison of real experiments and simulations.read more

Analytical formulae for path loss prediction in urban street grid microcellular environments
Q. Sun,Soon Yim Tan,Kah Chan Teh +2 more
TL;DR: Analytical propagation path loss formulae are derived based on the geometrical optics and diffraction theory and they take into account multiple reflections along street walls and diffractions around street corners with ground reflections neglected; i.e., a two-dimensional approach.
