In this paper we propose an approach for solving problems of optimal resource capacity allocation to a collection of stochastic dynamic competitors. In particular, we introduce the knapsack problem for perishable items, which concerns the optimal dynamic allocation of a limited knapsack to a collection of perishable or non-perishable items. We formulate the problem in the framework of Markov de...

Radars equipped with an Electronically Scanned Antenna (ESA) have the potential of directing the electromagnetic radar beam without mechanically adjusting the antenna. Furthermore, the beam can be redirected instantaneously towards any location in space. Hence, the mechanical constraint of a traditional antenna, which imposes the typically revolving measurement pattern, is relaxed. This means, ...

In this paper, we consider a wireless relay-aided Orthogonal Frequency Division Multiple Access (OFDMA) network, where there are a Base Station (BS), multiple Relay Stations (RSs) and Mobile Stations (MSs). we assume that individual MS is already allocated to its serving sector which is served by BS directly or through RSs. To maximize the total sum of utility functions of average packet delays...

A resource management methodology for collaborative computing systems over multiple virtual machines (CCSMVM) is presented to increase the performance of computing systems by improving the resource utilization, which has constructed a scalable computing environment for resource on-demand utilization. We have designed a resource management framework and a prototype to improve resource utilizatio...

We address the optimization of the sum rate performance in multicell interference-limited singlehop networks where access points are allowed to cooperate in terms of joint resource allocation. The resource allocation policies considered here combine power control and user scheduling. Although very promising from a conceptual point of view, the optimization of the sum of per-link rates hinges, i...

Yin Sun, Xiaofeng Zhong, Tsung-Hui Chang, Shidong Zhou, Jing Wang, and Chong-Yung Chi Abstract This paper studies the spectrum sharing problem between a cooperative relay network (CRN) and a nearby ad-hoc network that operates over the same spectral band. In the uplink CRN transmission, both the source node and relay node can interfere with the ad-hoc links. By virtue of that the CRN can predic...

In large and complex communication networks, architectural decisions regarding functionality allocation are often more important than the details of the resultant resource allocation algorithms themselves. Optimization theory is a powerful tool for designing architectures and providing the structures algorithmic structures for communication networks. Starting with fair resource allocation as th...

Resource allocation problems are concerned with the allocation of limited resources among competing activities so as to achieve the best overall performances of the system but providing fair treatment of all the competitors. Telecommunication networks are facing the increasing demand for Internet services. Therefore, a problem of network dimensioning with elastic traffic arises which requires t...

This paper studies multiuser orthogonal frequency division multiplexing (OFDM) system using adaptive subchannel and power allocation with partial channel information. Previous research on multiuser OFDM includes margin adaptive (MA) optimization and rate adaptive (RA) optimization. The capacity gain using adaptive resource allocation over fixed resource allocation such as time division multiple...

Task Scheduling and Resource Allocation is an important phase in Project Management. Scheduling Problem in Software Projects is NP-complete and various algorithmic approaches have been studied to develop an optimal solution to generate a schedule, which will be cost effective, utilize resources effectively and meet the target deadline. This paper addresses the above problem in detail and review...
