This paper is concerned with the resource allocation problem for a multiservice network link with unicast and multicast connections. The objective is to allocate capacity on the link such that the carried load is maximized. We develop an approximate method to solve the problem and also present an estimation of its accuracy and some numerical results.
Resource allocation is an important issue in cognitive radio systems. It can be done by carrying out negotiation among secondary users. However, significant overhead may be incurred by the negotiation since the negotiation needs to be done frequently due to the rapid change of primary users' activity. In this paper, a channel selection scheme without negotiation is considered for multi-user and multi-channel...
Dissemination control is concerned with controlling electronic resources even after they have been delivered to a legitimate recipient. This paper proposes a secure resource dissemination system framework in which resource providers and recipients are interacted mutually in an anonymous, accountable, and trustworthy way, while security constraints on diverse resources can be continuously protected...
It has become a hot research topic in manufacturing system that manages the manufacturing system's life cycle resources uniformly, normally and effectively, realizes the sharing of remote and heterogeneous resources and optimizing the allocation of the manufacturing resources. The modeling and resource management approach of Resource Space Model (RSM) meet the needs of the requirements of managing...
HLA-based simulations, as any distributed computing application, can undergo critical performance issues due to load imbalances on large-scale, heterogeneous, non-dedicated distributed systems. Such imbalances are produced by HLA simulation entities that can dynamically change their computation and communication load during their execution time, so an initial static load deployment is incapable of...
A kind of management model in the mobile transmission resource management system (short for TRMS) is presented . With this model, the efficiency, expansibility of managing the transmission resource can be improved and the complexity can be reduced.
Cooperative relaying transmission is proved to be a feasible method for QoS guaranteed and dead-spot coverage. In this paper, the power and frame allocation schemes are proposed for TDD-based cooperative relaying system. Based on the related work on adaptive frame allocation (FA), the optimal power allocation (PA) is deduced for compress-and-forward (CF) relaying, and the optimal PA and FA schemes...
Cloud Computing, the long-held dream of computing as a utility, has the potential to transform a large part of the IT industry, making software even more attractive as a service and shaping the way IT hardware is designed and purchased. In this environment, any application needs a model of to achieve elasticity and the illusion of infinite capacity requires each of these resources to be virtualized...
The Bandwidth Broker proposed to manage the resources for DiffServ networks has two ways to implement, namely centralized and distributed approach. The distributed Bandwidth Broker offers scalability advantages over the centralized one, but the improper pre-compute of resource will make its bandwidth allocation unfair. The solution to this issue is characterized by a new fairness criterion, multi-path...
In grid computing, resources can be given and retrieved by grid nodes freely. The wide range of selection and the high degree of strangeness bring lots of problems in secure selection of grid. Efficient resource allocation and utilization can hardly be achieved without the assurance of a high degree of confidence relation. In this paper, we propose a solution based on trust mechanism. The trust management...
The developed DnD grid system aims to improve building of distributed computer environments by dedicated and non-dedicated resources. The proposed approach supposes overdimensioned static performance and dynamic underloading of non-dedicated resources. Efficiency, availability and autonomy of such distributed heterogeneous environment depend on platform, application, mapping and resource owner/service...
This paper deals with the reduction of energy consumption in large scale systems, especially by taking into account the impact of energy consumption for server consolidation. Decreasing the number of physical hosts used while ensuring a certain level of quality of services is the goal of our approach. We introduce a metric called energetic yield which represents the quality of a task placement on...
A two-user decision making game is studied in the OFDM based subscriber cooperative relaying network, in which subscribers transmit their own data in the first phase, while helping to retransmit their partner's or choosing to freeride in the second phase. In the paper, we study a hierarchical game (HG) for a two user coalition, where cooperation is preferred and total payoff is transferable. Instead...
Applications for wireless sensor networks may be decomposed into the deployment of tasks on different sensor nodes in the network. Task allocation algorithms assign these tasks to specific sensor nodes in the network for execution. Given the resource-constrained and distributed nature of wireless sensor networks (WSNs), existing static (offline) task scheduling may not be practical. Therefore there...
Decisions on ldquoWho should fix this bugrdquo have substantial impact on the duration of the process and its results. In this paper, optimized strategies for the assignment of the ldquorightrdquo developers for doing the ldquorightrdquo task are studied and the results are compared to manual (called ad hoc) assignment. The quality of assignment is measured by the match between requested (from bugs)...
We describe the architecture of PHAROS (Petabit Highly-Agile Robust Optical System), developed under the DARPA CORONET program. PHAROS provides traffic engineering, resource management and signaling solutions for highly-agile, large-capacity core optical networks. PHAROS technology facilitates rapid configuration of network resources to address dynamic traffic needs in future global military and commercial...
The problems of resource allocation and the characterization of cooperative behavior in a two-user fading multiple-access channel (MAC) in the presence of uncertainty about the channel state information at the transmitters (CSIT) are considered. Game-theoretic techniques are used to characterize cooperative behavior and obtain the system operation point from an individualistic perspective. A two-user...
Four utility-based criteria are considered to study dynamic resource allocation in Multiple Input Multiple Output - Orthogonal Frequency Division Multiple Access (MIMO-OFDMA) multiuser cellular systems. In these criteria, two generalized bargaining strategies, GNBS and KSBS, are used to emphasize different levels of user fairness, while the criteria of utilitarian and egalitarian are briefly discussed...
As the number of users increases, the amount of required feedback Channel State Information (CSI) at the base station becomes huge and prohibits the feasibility of conventional adaptive resource allocation algorithms in fairness-aware downlink OFDMA systems. Thus, this paper presents a novel mechanism making use of multi-user diversity to greatly reduce the feedback CSI while maintaining almost the...
A mission critical environment (MCE) consists of error-prone, highly variable, and highly rate limited communication channels. Paradoxically, this substantially increases the need to perform optimal task allocation (OTA), while at the same time making it much harder to perform OTA efficiently. To simplify the problem, we consider OTA for publish/subscribe-based MCE since it has unique characteristics...
