Assuming wireless communication in scale-free networks, the local routing model can be extended with a novel approach which takes spatial information into account as well. The properties of the proposed model are analyzed in this paper also when the nodes of the network are moving along straight lines in the unit square.

Topology estimation method for telecommunication networks
Telecommunication Systems, 2018Network topology specifies the interconnections of nodes and is essential in defining the qualitative network behaviour which is known to be universal with the similar phenomena appearing in many complex networks in diverse application fields. Topology information may be uncertain, or several pieces of inconsistent topology information may exist.

Topology Discovery for Telecommunications-carrier Networks using Equipment Alarms
2020 21st Asia-Pacific Network Operations and Management Symposium (APNOMS), 2020As for the service assurance operation of telecommunications carriers, accurate information about a network topology which indicates the connection relationships between pieces of network equipment is necessary. However, the network of a telecommunications carrier has several hundreds of thousands of equipment, and its topology is frequently ...

A quantitative measure for telecommunications networks topology design
IEEE/ACM Transactions on Networking, 2005This paper proposes a new measure for network performance evaluation called topology lifetime. The measure provides insight into which one of a set of topologies is likely to last the longest before more capacity must be installed. The lifetime measure is not single valued, but considers growth as a function of a set of demand shifts (perturbation ...

Heuristic methods for topological design of telecommunication networks
European Transactions on Telecommunications, 2005AbstractThe paper addresses a generic topological network design problem. The target of the optimisation is to determine a network structure and a demand allocation pattern that would minimise the cost of the network, given a list of potential node locations and a list of admissible interconnections between these nodes. Since the problem is known to be

Topological Design of Two-Level Telecommunication Networks with Modular Switches
Operations Research, 2000In this article we propose a mixed 0-1 linear programming model for the topological network design problem with modular switches such as the ones that will be used in asynchronous transfer mode (ATM) frame relay and other broadband networks. The model includes the location of switches, their configuration with respect to ports and multiplexers, the ...

A quantitative measure for comparison between topologies of modern telecommunications networks
Globecom '00 - IEEE. Global Telecommunications Conference. Conference Record (Cat. No.00CH37137), 2002This paper proposes a new measure for network performance evaluation called topology lifetime. The measure provides insight into which one of a set of topologies is likely to last the longest before more capacity must be installed. The lifetime measure is not single valued, but considers growth as a function of a set of demand shifts.

Telecommunications network topological design and capacity expansion: Formulations and algorithms
Telecommunication Systems, 1993This paper formulates the network topology and capacity expansion problem in a telecommunications network and suggests a family of heuristics and a dual-based lower bounding procedure for solving it. They include schemes exploiting special subproblem structures, decomposition of the problem using Lagrangian relaxation, and a global search strategy ...

Topological clusterisation for fault management in large telecommunication networks
9th Asia-Pacific Conference on Communications (IEEE Cat. No.03EX732), 2004The work reported here is concerned with the process of arranging network topological information into clusters according to the relevant area of failure restoration. The clusterisation outcome is determined by employing "level structure" arrangement with reference to each possible failure scenario.
