Universal Path Gain Laws for Common Wireless Communication Environments

Wireless Communication Protocols for Distributed Computing Environments

The distributed computing is an approach relying on the presence of multiple devices that can interact among them in order to perform a pervasive and parallel computing. This chapter deals with the communication protocol aiming to be used in a distributed computing scenario; in particular the considered computing infrastructure is composed by elements (nodes) able to consider specific applicati...

Path Loss Measurements for Wireless Communication in Urban and Rural Environments

Corresponding Author: Yahia Zakaria Engineering Research Division, National Research Center, Dokki, P.O. 12622, Cairo, Egypt Email: [email protected] Abstract: Path loss models are useful planning tools that allow the designers of wireless communication networks to achieve optimal levels for the base station deployment and meeting the expected service level requirements. In this study variou...

Modeling Urban Environments for Communication Aware UAV Path Planning

The presented work introduces a graph based approach to model urban (or otherwise cluttered) environments for UAS utilization beyond line-of-sight as well as out of direct R/F range of the operator’s control station. Making the assumption that some a priori data of the environment is available, the proposed method uses a classification of obstacles with respect to their impact on UAV motion and...

Universal laws for hierarchical systems

Organisms are hierarchically organized, both structurally and behaviorally, where one level is defined to be above another level if the objects from the latter are combined together to make objects of the former level. I say that such a pair of levels is a combinatorial system. To understand organisms will require appreciating the relationships between all pairs of adjacent hierarchical levels ...
