Smart optimisation of radio resource distribution techniques is crucial in improving the overall performance of Next-Generation Networks (NGNs). Since higher data rates, lower latency and increased fairness for users are the main goals, an efficient scheduling algorithm has to be used. In this paper an evaluation of the performance of an indoor network is realised using the Realistic Indoor Environment...
For the evaluation of station importance in transportation system of railway, firstly the weighted railway passenger bipartite network model was established according to the idea of the transport capacity between the different traffic units and connection relation between the traffic units and their stations. Based on previously mentioned network model, a resource allocation algorithm was proposed...
Although federated cloud computing has emerged as a promising paradigm, autonomous orchestration of resource utilization within the federation is still required to be balanced on the basis of workload assignment at a given time. Such potential imbalance of workload allocation as well as resource utilization may lead to a negative cloudburst within the federation. The analytical models found in the...
In this paper, an analytical model for assigning tasks to the actors is presented. The model is based on queuing networks and tries to minimize the network make-span in wireless sensor and actor networks. To achieve this goal, through a steady state analysis of the proposed model to solve equations and inequalities, the best distribution rates of tasks to the actors are calculated. It is shown that...
Anticipatory networking is a recent branch of network optimization that exploits contextual information to improve resource allocation decisions based on prediction. While some anticipatory networking concepts have been proposed in the literature, understanding of the potential real-world gains is so far very limited. Future mobile networks will likely integrate such mechanisms, and thus it is of...
One technique of solving energy consumption and performance issues in virtualized data centers consists in migrating the virtual machines between the physical hosts, in order to achieve either resource consolidation or load balancing. These migrations, however, may degrade the performance of the virtualized applications and of the servers and network involved in the migration process. A possible solution...
In recent years, photovoltaic (PV) penetration has significantly increased in distribution networks. In the future, it will be more and more important to predict how much and where PV will be installed. Existing agent-based PV diffusion models just considered the spreading of residential PV, but actually there is a large amount of non-residential PV such as industrial and commercial. Its effect should...
In this paper, we investigate the propagation coupling loss (captures all sources of attenuation between serving cell and mobile station (MS)) and geometry metric (GM) (downlink average signal-to-interference plus noise ratio) performance of mmWave cellular networks for outdoor and indoor MSs, considering urban micro (UMi) environments. Based on these studies, we identify effective mmWave frequency...
Petri nets prepare an effective method of computing minimal siphons and elementary siphons based on the concept of initial resource assignment on liveness for the class of generalized Petri nets, namely S4PR. At the point when consideration concentrates on the utilization of framework assets to flexible manufacturing system (FMS) can be viewed as an exceptional class of simultaneous of resource allocation...
In view of the fact that there is no comprehensive evaluation parameter of support equipment allocation efficiency, in this paper, we had a comprehensive consideration of the mean logistic delay time and the annual consumption cost of support equipment, and analyzed and constructed the optimization model of allocation efficiency from the perspective of cost-effectiveness with the constraint of satisfaction...
Public-private partnership (PPP) model has become an important solution of governments to provide infrastructures. In the execution of the PPP projects contracts, however, inevitably to renegotiate, which might affect the execution efficiency of PPP contracts. This paper built two PPP projects renegotiation bargaining game models of the private sectors and public sectors respectively through the analysis...
The ever-growing amount of textual data available online creates the need for automatic text summarization tools. Probabilistic topic models are able to infer semantic relationships between sentences which is a key step of extractive summarization methods. However, they strongly rely on word co-occurrence patterns and fail to capture the actual semantic relationships between words such as synonymy,...
Aiming at the inventory management problem of metro vehicle repairable spare parts, a two-echelon inventory model based on METRIC (Multi-Echelon Technique for Recoverable Item Control) theory is proposed. Firstly, analyze the state transition process of metro vehicle repairable spare parts. Secondly, establish the two-echelon inventory management model according to the inventory characteristics of...
We propose a dynamic portfolio rebalancing approach within the mean-risk framework, in which the riskaversion coefficient is adjusted according to market trend information captured by a technical indicator. We employ Gini's Mean Difference as the risk measure and the moving average as the technical indicator. We conduct a thorough empirical evaluation with a rolling horizon approach using the S&P...
An optimum resource partition decision model for a class of warfare command systems in conflicts of two opponents, where the total forces of operational side is not superior to the forces of enemy side, on the grounds of Lanchester square law equations has been developed. The issue on how to solve the maximum residual strength of the operational side against the enemy is thoroughly addressed. The...
In this position paper, we provide a discussion of the need for new mechanisms towards optimizing the performance of the firth generation (5G) wireless systems, and then we outline on-going research work and results in this direction. Initially we go over the recently proposed concept of network anticipation and then resource allocation, since these two themes form the core of the ACT5G research project...
Network slicing to enable resource sharing among multiple tenants-network operators and/or services-is considered a key functionality for next generation mobile networks. This paper provides an analysis of a well-known model for resource sharing, the ‘share-constrained proportional allocation’ mechanism, to realize network slicing. This mechanism enables tenants to reap the performance benefits of...
A lot of work on resource estimation has been carried out in the area of cloud computing. For example, some recent models assign resources based on the history of the users and the utilization of the cloud resource pool. Although these models have generally shown an increase in server utilization, they lack a cost-benefit analysis to know the profit margin obtained by the respective resource allocation...
We consider two-hop Device-to-device (D2D) relaying in multi-cell downlink networks. D2D relaying is envisioned to be a promising cell coverage extension technique, which can provide improved cell-edge performance without a dense infrastructure deployment. Relaying complicates the resource allocation and interference management in multi-cell networks. We first study the aggregate co-channel interference...
