structural characteristics and spatial distribution of major farming systems in mountain environment of the iranian plateau as well as their developments in the past few decades have been studied by statistical analysis. using this new approach, towards the study of natural resource allocation methods in mountains of iran, the following resulted: land and resource use practices have followed a ...

The paper underlines the main advantages and drawbacks of IP routing. Some possibilities for resolving of routing problems are analyzed. A motivation for the use of Soft Computing Technologies (SCT) and Multiple Protocol Label Switching (MPLS) protocol for solving network routing problems is shown. The basic concept of the MPLS networks are described. Some definitions of Soft Computing Agents (...

Within the last 15 years, a variety of unsolved problems of interest primarily to operations researchers, computer scientists, and mathematicians have been demonstrated to be equivalent in the sense that a solution to any of them would yield a solution to aH of them. This class of problems, known as NP-complete, contains many long-standing problems of scheduling, routing, and resource allocatio...

Network routing –being a central part of our everyday life, which increasingly depends on internet services– is highly distributed. It must provide for a variety of different services, each accommodating different requirements. Thereby, the access to network services is often very different between multiple users or agents, who are nonetheless expecting the same quality, e.g., regarding speed o...

We present an approach to resource allocation in telecommunications networks based on the interaction of self-interested agents which have limited information about their environment. A system architecture is described which allows agents representing various network resources, potentially owned by different real-world enterprises, to coordinate their resource allocation decisions without assum...

Dynamic routing in WDM (Wavelength Division Multiplexing) networks is achieving increasing interest due to the expected traffic growth for future optical networks. This contribution concentrates on network performance issues occurring for network operation under dynamic traffic load. In this context, routing strategies play a central role. We show that a new strategy achieves very good performa...

My Ph.D. research is focused on the resource allocation problem in wireless networks in the presence of flow-level dynamics. The resource allocation problem is a key problem in wireless networks due to limited bandwidth and extensive noises and interferences. I first investigated the scheduling problem in wireless cellular networks, and developed throughput-optimal scheduling algorithms, for si...

The TEFID framework for Traffic Engineering in Future Internet Domains is outlined. The framework provides QoS and GoS by a set of inter-dependent traffic control and resource allocation functions. Traffic engineering relies on a relationship between three models: traffic model, network model, and performance model. The objective is to achieve fair and efficient sharing of resources among the n...

Missing link prediction of networks is of both theoretical interest and practical significance in modern science. In this paper, we empirically investigate a simple framework of link prediction on the basis of node similarity. We compare nine well-known local similarity measures on six real networks. The results indicate that the simplest measure, namely common neighbors, has the best overall p...

This paper investigates the centralized resource allocation with centralized structures by using the data envelopment analysis-ratio (DEA-R) models. To this end, it proposes a method to determine the resource allocation of centralized structures such that the ratio of inputs to outputs are minimized.
