In order to balance the number of outbound and inbound tasks of each aisle and improve the working efficiency of the multi-tier shuttle system, three principles of storage location assignment were put forward: the principle of minimum correlation degree, the principle of equalization of product items and the principle of equalization of tasks, which were expected to be followed when storing products...
The emergence of 5G wireless communication calls for new paradigms to satisfy the individuation and diversification of users' demands. In this paper, we construct the multicast groups under the guidance of user interest and then allocate the subcarriers and power to these groups in orthogonal frequency division multiple (OFDM) networks. Specifically, in order to maximize the social utility related...
In order to improve picking efficiency of the automatic picking system with preparatory picking buffer and solve the adaptation problem between order structure and equipment, a mathematical model of picking efficiency is established. The model is based on parallel picking. To solve the model, a heuristic algorithm is proposed for allocating picking tasks. The correlation between single order picking...
Machine-to-Machine (M2M) communications is regarded as an important enabler towards the realization of the Internet of Things (IoT). M2M communication also referred to as machine type communication (MTC) enables devices to communicate directly or via a network gateway over the cellular network without or with-limited human intervention. Most MTC devices are operated by batteries and it is very critical...
Virtual machine consolidation and scheduling influence directly the cloud cost and performance. They play an important role in cloud service granting helping to achieve execution efficiency, user Service Level Agreement (SLA) compliance, utilization of resources, energy saving, and the increasing profit of cloud providers. In this paper the authors propose the Optimization using Simulated Annealing...
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...
Though auction has been exploited to deploy services or allocate resources in the literatures, an efficient truthful auction mechanism is required to charge service providers as buyers for deployable locations as sellers in a Cloud-Integrated WOBAN(CIW)[1]. In this paper, we first design a truthful auction mechanism for service deployment in a CIW, which can be divided into two stages: the match between...
In the new Digital Economy, massive computer systems, often grouped in datacenters, serve as factories "producing" cloud services with massive consumption. However, to afford cloud services globally, we must address new research challenges in designing, operating, and using modern datacenters. We must also address challenges in educating and training the next generation of datacenter engineers...
An advanced dynamic spectrum allocation scheme based on fairness aware and fragmentation reduction is proposed to address the service fairness problem. Simulation results imply that the proposed scheme can greatly improve service fairness and reduce spectrum fragmentation.
The distribution and use of network resources should be evaluated in order to reduce the computational and financial costs incurred in the deployment and maintenance of the network. This work presents a methodology for cost-benefit evaluation of different regenerator placement and allocation techniques for elastic optical networks. The proposed methodology is applied in scenarios with dynamic traffic...
We present heuristic algorithms for the efficient resource partitioning in the NEPHELE datacentre optical interconnect. The algorithms aim to segment the network into smaller and isolated virtual datacentres (VDCs), where all racks are able to communicate at full capacity irrespective of their placement. Since the NEPHELE architecture relies on shared optical rings, the isolation of VDC traffic is...
Cloud computing is increasingly based on geographically distributed data centers interconnected by high performance networks. Application of Software Defined Networking (SDN) is studied as an emerging solution to support dynamic network resource management for distributed data centers (DCs) jointly with extensive use of Network Function Virtualization (NFV). SDN/NFV operation takes advantage of orchestration...
Edge cloud computing is a trending paradigm, which extends cloud computing by additionally utilizing computing resources at the network edge, e.g., at mobile base stations. Especially personalized services can be instantiated or migrated close to end users, which improves the latency and supports user mobility. However, the placement of the service chains is crucial for the performance of the services...
This paper evaluates the performance of the first-last-exact fit spectrum allocation policy for elastic optical networks. The first-last-exact fit spectrum allocation policy is intended to increase the number of aligned available slots and avoid small contiguous available slots, and hence suppresses the blocking probability. This policy separates the allocation of disjoint and non-disjoint connections...
Cloud computing has enabled provisioning of scalable and virtualized resources to organizations in an ubiquitous and on-demand manner. Likewise, configurable process modeling has enabled organizations to reuse their existing knowledge by sharing a reference process model between different tenants that can be customized according to specific needs. Nevertheless, there are some limitations in this context,...
This paper presents an architecture for digitally managing dc power distribution within a building using a network model, a system for simulating specific systems, and results from initial use of the model. The architecture implements the Local Power Distribution model [7] based on networks of nanogrids, with local prices as the mechanism for determining the direction, magnitude, and timing of power...
With cloud computing, the efficient management of resources is of great importance as an increased utilization of the available resources can result in higher scalability and significant energy and cost reductions. Experimental validation of novel resource management strategies is costly and time consuming, and often requires in-depth knowledge of and control over the underlying cloud platform. As...
Device-to-device (D2D) communication allows mobile devices to directly communicate with each other without infrastructures. It is considered as a promising solution to improve communication performance such as spectral efficiency and network capacity of the fifth generation (5G) wireless communication systems as well as LTE-Advanced (LTE-A) systems. It generally requires D2D discovery and data communication...
In recent years many organizations such as, Amazon, Google, Microsoft, have accelerated the development of their cloud computing ecosystem. This rapid development has created a plethora of cloud resource management interfaces for provisioning, supervising, and managing cloud resources. Thus, there is an obvious need for the standardization of cloud resource management interfaces to cope with the prevalent...
