Aerial Adhoc Networks are the new class of wireless adhoc networks, where node motion is not restricted in 2D plane as in (VANETs) but rather a 3D plane as these wireless nodes may be mounted on board Unmanned Aerial Vehicles (UAV). Current research literature argues that since flights occur at high altitudes, Line of Sight (LoS) propagation models suffice for such wireless transmissions between nodes...
In this work several empirical propagation models have been studied based on many signal strength measurements in an indoor environment (Ophthalmology Specialized Hospital) using log-distance model for LOS (Line of Sight) area and MWM (Multi-Wall Model) for NLOS (Non Line of Sight) areas. The building is typical in Iraq (more than 85% of the buildings have this structure). It has two types of walls,...
The interior of a right-angled impedance wedge is a natural model of a corner reflector and is of interest in the development of wireless propagation models. Using a previously-developed solution for the diffraction of a plane wave by a wedge of arbitrary angle, the geometrical optics field is determined and the diffracted field is computed. If an impedance compatibility condition is not met, the...
