In this paper, we study resource allocation problem in orthogonal frequency division multiple access multiple-input multiple-output (OFDMA-MIMO) relay systems and formulate the optimal instantaneous resource allocation problem including subcarrier assignment, relay selection and power allocation to maximize system capacity. Based on the assumption that the availability of perfect channel state ...

This paper makes two contributions. First, we introduce a model for evaluating the performance of data allocation and replication algorithms in distributed databases. The model is comprehensive in the sense that it accounts for I/O cost, for communication cost, and for limits on the minimum number of copies of the object (to ensure availability). The second contribution of this paper is the int...

As businesses are increasingly relying on the cloud to host their services, cloud providers are striving to offer guaranteed and highlyavailable resources. To achieve this goal, recent proposals have advocated to offer both computing and networking resources in the form of Virtual Data Centers (VDCs). Subsequently, several attempts have been made to improve the availability of VDCs through reli...

Food availability can influence the optimal allocation of time and energy among alternative behaviors such as foraging, courting, and competing for mates. If populations differ consistently in food availability, selection may cause geographic divergence in allocation strategies. At the opposite extreme, a norm of reaction may evolve such that food intake influences the allocation strategy of in...

The limited availability of radio frequency spectrum will require the future wireless systems to use more eecient and sophisticated resource allocation methods to increase network capacity. In this work we propose a Joint Resource Allocation Algorithm (JRAA) that makes the channel base station and power assignment in a wireless network with arbitrary number of base stations and mobiles attempti...

We consider users bidding in a series of multi-unit sealed-bid auctions, aiming at reserving the same amount of units of the resource auctioned, e.g. transmission slots in a wireless network. Each user attains from each successful allocation of resource units an instant marginal utility that depends on his history of resource allocation. The user’s bid at each auction equals this marginal utili...

In order to consider the importance of efficient and judicious use of available resources, a case study was undertaken to allocate the land under selected crops in command area of Aundha Minor irrigation project, of Maharashtra State, India so as to maximize the net benefit and production. A linear programming allocation model was formulated by considering the four objectives viz. (i) the maxim...
