The problem of routing virtual circuits according t o dynamic probabilities in virtual circuit packe t switched networks is considered. Queueing network models a r e introduced and performance measures a re defined. A decentralized asynchronous adaptive routing methodology, based on learning automata theory is presented. Every node in the network has a stochastic learning automaton as a router ...

A mobile ad hoc network (MANET) is a wireless network that uses multi-hop peer-topeer routing instead of static network infrastructure to provide network connectivity. MANETs have applications in rapidly deployed and dynamic military and civilian systems. The network topology in a MANET usually changes with time. Therefore, there are new challenges for routing protocols in MANETs since traditio...

One of the most important problems for distribution companies is to find the best locations for depots and to find proper routes for transportation vehicles and to optimize supply network. This study intends to develop a model for the problem of location-routing in post offices. So, a new Bi-Objective Location-Routing Problem for Locating Town Post Office and Routing Parcels is defined. This pr...

Problem statement: In this study, an attempt had been made to compare the performance of the reactive ad-hoc routing protocols using OPNET modeler with respect to increasing number of nodes in the network. Approach: In present study, we compared various reactive routing protocols such as Ad hoc On-demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Temporally Ordered Routing Algorit...

-Consider an optical network which employs wavelength-routing crossconnects that enable the establishment of wavelength-division-multiplexed (WDM) connections between node pairs. In such a network, when there is no wavelength conversion, a connection is constrained to be on the same wavelength channel along its route. Alternate routing can improve the blocking performance of such a network by p...

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...

An efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. The implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. According to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses Fuzzy Inference Systems to select cluster head. The alg...

This paper presents a novel routing scheme for wireless mobile networking which is adaptive to the mobile traffic patterns. We propose a concept called ‘‘friend network” to accommodate the need for effective routing information update. Our routing scheme has the advantages of minimizing network bandwidth consumptions, providing optimal routing, and addressing network security concerns at the sa...

How should ows through a network be organized, so that the network responds sensibly to failures and overloads? The question is currently of considerable technological importance in connection with the development of computer and telecommunication networks, while in various other forms it has a long history in the elds of physics and economics. In all of these areas there is interest in how sim...

Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile hosts forming a temporary network without the aid of any stand-alone infrastructure or centralized administration. Most of the proposed MANET protocols do not address security issues. In MANETs routing algorithm is necessary to find specific routes between source and destination. The primary goal of any ad-hoc network routing prot...
