Heuristic algorithms in topological design of telecommunication networks

Journal of Telecommunications and Information Technology, 2003
The paper addresses the generic topological network design problem and considers the use of various heuristic algorithms for solving the problem. The target of the optimisation is to determine a network structure and demand allocation pattern that would minimise the cost of the network, which is given by fixed installation costs of nodes and links and ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective

Advanced Electronic Materials, EarlyView.
Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

3D models of switching patterns of switching plants on elements by Berezovsky [PDF]

Trudy Odesskogo Politehničeskogo Universiteta, 2018
A feature of modern switching structures, systems, networks (SSSN=3SN) is a two-dimensional (2D) topology that is used in many commercial systems. Traditional SSSN is regular, but static – do not correspond to the rapid dynamics of the development of ...

Fuzzy based load and energy aware multipath routing for mobile ad hoc networks [PDF]

, 2015
Routing is a challenging task in Mobile Ad hoc Networks (MANET) due to their dynamic topology and lack of central administration. As a consequence of un-predictable topology changes of such networks, routing protocols employed need to accurately capture ...
