This paper studies fair resource allocation schemes for orthogonal frequency-division multiple-access (OFDMA) with the decode-and-forward relaying strategy. To satisfy the heterogenous rate requirement of each user while considering the fairness and efficiency as performance indices, the bargaining theory is applied to allocate resource at a relay node to multiple source nodes. Motivated by the fact...
Grid has evolved dramatically into the era of service-oriented grid, which facilitates building of large-scale systems in standard fashions, reusability of essential functions, and interoperability among components. However, grid resource allocation is still a challenging problem for which a grid scheduler has to be operating in a dynamic and uncertain environment. Conventional scheduling algorithms...
Deadlock avoidance in sequential resource allocation and concurrency control is a well-defined problem. The problem is extensively studied and investigated in order to define a safe, i.e. deadlock free, scheduling mechanism to a set of finite-resources. Originally a simple graphical solution has been given theoretically, however, practically the problem has been studied by defining deadlock avoidance...
This paper focuses on the resource scheduling of LTE-Advanced system with carrier aggregation. With different fading characters, the aggregated carriers have different coverage between each other. Consequently, the carrier aggregation causes that the number of carriers which users can be scheduled on is various. The allocation fairness can not be achieved with the original proportional fair (PF) scheduling...
Aviation project which always involves too many resources need to do resource leveling for enhancing the utilization of resources so as to reducing project cost. Intelligent optimization algorithms and heuristic approaches are inefficient and inflexible when solving large-scale aviation resource leveling problems. A hybrid algorithm based on Artificial Immune Algorithm (AIA) and Ant Colony Optimization...
Several decentralized load balancing policies have been proposed to address the issue of scalability in grids.However, the communication overhead incurred in exchanging state information remains a burden. In this paper, we propose a dynamic, decentralized load balancing policy which performs very competitively in heterogeneous grids. The policy uses an effective mechanism for state information exchange,...
This paper firstly introduced the basic idea of task requirement driven sensor management (TRDSM) and analyzed the task requirement of target tracking. Then, a new approach is proposed to deal with the multi-sensor management problem. The new method uses centralized management model to control sensors and the method comprehensively considers target priority and sensor usage cost. Then, sensors resource...
Resource pools are collections of computational resources which can be shared by different applications. The goal with that is to accommodate the workload of each application, by splitting the total amount of resources in the pool among them. In this sense, utility functions have been pointed as the main tool for enabling self-optimizing behaviour in such pools. The goal with that is to allow resources...
Economic models have shown their suitability to allocate resources efficiently, considering an unbalanced supply and demand. As the use of the Grid is extending, a numerous set of distributed resource allocation frameworks have been developed to attain efficient resource management while keeping the scalability of the Grid. However, those frameworks make use of either simple double auction mechanisms...
The next generation of wireless networks will simultaneously support any data and voice users. These users or UEs (User Equipment) will share the uplink and downlink radio resources and so, in each frame, the basestation must signal which UEs are being allocated resources and the location within the frame of the associated data. In the case of the Long Term Evolution (LTE) wireless standard, this...
In this paper, we present a system that optimally and dynamically allocates the available computing resources to virtual machines that support virtual collaboration environments. Such environments are emerging fast via on-line social networks, virtual worlds, and the "Web 3.0" or "collaborative Web" paradigm. We use a utility-based framework to differentiate the applications hosted...
Because of the dynamic nature and an instability of grid computing environment, system behavior in terms of QoS depends crucially on the selection of appropriate subset of the available resources. Thus, a well-defined system model that provides high system availability using a scheduling mechanism is required. In this paper, we propose the SLA based Policy Administrator (SPA) with QoS constraints...
This paper addresses a cooperative jamming resource allocation problem in electronic warfare and presents a resource allocation model of cooperative jamming (CJRA). Besides the capabilities and number of available jamming resources, the model also takes many constrains into account. Then an improved immune genetic algorithm (IIGA) is presented to solve the problem. In order to prevent the algorithm...
Implementation of heterogeneous wireless networks is a key issue that needs to be attended for delivering 4G services. The concept of reconfigurable interoperability defines mechanisms for coexistence of the wireless networks and intelligent management and reconfiguration within such systems. This paper elaborates the design of reconfigurable interoperable wireless communication system (RIWCoS). It...
The stringent performance and area constraints and short time to market of modern digital systems drive us towards automated methods for producing high speed and low area architecture with optimum features. In this paper, we present a new algorithm, which automatically maximizes resource optimization of data path while meeting performance constraints. The main input of this algorithm is the control...
Resource allocation is a critical issue for Wireless Sensor Networks (WSNs) especially for Ultra-Wide Band (UWB) based networks. In this paper, we present frequency allocation scheme for an efficient spectrum management that is able to statically assign control channels and dynamically reuse data channels for Personal Area Networks (PANs) inside a Large-Scale WSN based on UWB technology. The frequency...
Resource allocation in software development is important and many methods have been proposed. Related empirical research is yet scarce and evidence is required to validate the theoretical methods. This paper introduces the staffing pattern as a metric of resource distribution among project phases, and verifies its effect on software quality and productivity using real project data. The main findings...
In ubiquitous environment intelligent and transparent services are provided to the users anytime and anywhere. Ubiquitous systems can be effectively implemented using the agent technology, while the agent platform supports efficient and stable interaction among the agents. In this paper we propose a load-balancing scheme which considers agent state for fair and efficient resource allocation to the...
In this paper, an approach based on a fuzzy hybrid Petri net model is proposed to solve the resource allocation problem of workflow management systems. Initially, an ordinary Petri net model is used to show the main activities of the system and the different routings of the workflow process. Hybrid resource allocation mechanisms are modeled by hybrid Petri net with discrete transitions where discrete...
This paper presents a class of Petri nets that can well model ratio-enforced resource allocation systems (RASs). Such RASs are required to enforce certain ratio among their processes to meet a desired production plan. A ratio-enforced system of sequential systems with shared resources (RS4R) can model an RAS whose processes are described by state machines. Both a ratio-enforcing controller and liveness-enforcing...
