Wireless network parameters such as transmitting power, antenna height, and cell radius are determined based on predicted path loss. The prediction is carried out using empirical or deterministic models. Deterministic models provide accurate predictions but slow due to their computational complexity, they require detailed environmental descriptions. While less accurate, Machine Learning (ML) fa...

Background: The link prediction issue is one of the most widely used problems in complex network analysis. Link prediction requires knowing the background of previous link connections and combining them with available information. The link prediction local approaches with node structure objectives are fast in case of speed but are not accurate enough. On the other hand, the global link predicti...

This paper addresses a path loss prediction and optimization by means of Lee’s model for Jiza town, south of Amman city, Jordan. Data were collected from mobile companies in Jordan in the frequency band of 900, and 1800 MHz. The calibrated Lee’s, Hata, and Egli’s path loss models were compared with respect to the original collected data. It is found that for the 900 MHz Lee’s prediction model h...

This paper studies the impact of surrounding buildings on path loss and multipath delay spread for Personal Communication Services (PCS) operating inside of buildings. Measurements conducted inside three large office buildings in the San Francisco Bay area provide an extensive database for propagation models at 915 MHz and 1900 Wlz, and show variability in path loss and delay spread caused by m...

This Master thesis deals with wave propagation and starts with wave propagation basics. It briefly presents the theory for the diffraction over terrain obstacles and describes two different path loss models, the Hata model and a FFT-based model. The significance of this paper is that it gives the simulation results for the models mentioned above and presents a comparison between the results obt...

The research presented in this paper is a performance study of short-range NLOS ultraviolet (UV) communication system, using a Monte-Carlo-based system-level model, in which the channel parameters, such as the path loss and the background noise are experimentally measured using an outdoor UV communication test-bed. Various transceiver geometry and background noise condition are considered. Furt...

An algorithm is presented for online prediction that allows to track the best expert efficiently even if the number of experts is exponentially large, provided that the set of experts has a certain structure allowing efficient implementations of the exponentially weighted average predictor. As an example we work out the case where each expert is represented by a path in a directed graph and the...

Worldwide Interoperability for Microwave Access (WiMAX) is the latest broadband wireless technology for terrestrial broadcast services in Metropolitan Area Networks (MANs). WiMAX has potential success in its line-of-sight (LOS) and non line-of-sight (NLOS) conditions which operating below 11 GHz frequency. Estimation of path loss is very important in initial deployment of wireless network and c...
