mobile-ad-hoc-networks (manets) are self-configuring networks of mobile nodes, which communicate through wireless links. the infrastructure of a mobile ad hoc network (manet) has no routers for routing, and all nodes must share the same routing protocol to assist each other when transmitting messages. the main issues in manets include the mobility of the network nodes, the scarcity of computati...

In this paper, a comprehensive model for hub location-routing problem is proposed which no network structure other than connectivity is imposed on backbone (i.e. network between hub nodes) and tributary networks (i.e. networks which connect non-hub nodes to hub nodes). This model is applied in public transportation, telecommunication and banking networks. In this model locating and routing is c...

The recent emergence of multimedia applications has led to the deployment of various telecommunication technologies (e.g. IP, wireless) in addition to traditional PSTN (Public Switched Telephone Network) circuit switched networks. In this heterogeneous telecommunication world, users make calls without regard to the fact that the originating network may differ from the terminating network, and t...

The interaction between a complex socio-economic environment and the extremely fast pace of development of new telecommunication technologies and services justifies the interest in using multicriteria evaluation in decision making processes associated with several phases of network planning and design. Based on an overview of current and foreseen evolutions in telecommunication network technolo...

Routing in telecommunication networks rely on the definition of performance indicators called routing metrics. Popular routing metrics are the route throughput, end-to-end delay and jitter. However, in a delay tolerant network displaying link disruptions, these metrics may be questionable. This contribution proposes six metrics for characterising routes in a delay tolerant network. These metric...

The design of general finite multi-server queueing networks is a challenging problem that arises in many real-life situations, including computer networks, manufacturing systems, and telecommunication networks. In this paper, we examine the optimal routing problem in arbitrary configured acyclic queueing networks. The performance of the finite queueing network is evaluated with a known approxim...

In order to facilitate interoperability in a network composed of next generation lambda-switch-capable equipment, this document defines a standard lambda label format that is compliant with the Dense Wavelength Division Multiplexing (DWDM) and Coarse Wavelength Division Multiplexing (CWDM) grids defined by the International Telecommunication Union Telecommunication Standardization Sector. The l...

Today, Vehicular Ad Hoc Network (VANET) is an emerging technology. The routing problems in heterogeneous network become popular research area in the field of VANET for supporting different aspects of Intelligent Transportation System (ITS) applications. With the progress of wireless radio technology, telecommunication, various wireless specifications and protocols form the heterogeneous network...

The analysis of a bi-dimensional dynamic routing model for alternative routing telecommunication networks led to the identification of an instability problem in the synchronous path selection associated with the complex interdependencies among the coefficients of the objective functions and the computed paths for every node pair. In this paper an analytical model enabling to make explicit this ...
