to use services transparently in a distributed environment, the utility grids develop a cyber-infrastructure. the parameters of the quality of service such as the allocation-cost and makespan have to be dealt with in order to schedule workflow application tasks in the utility grids. optimization of both target parameters above is a challenge in a distributed environment and may conflict one ano...

OF THE THESIS Decentralized Spectrum Allocation Schemes for Cognitive Radio Networking by Srinivas Pinagapany Thesis Director: Prof. Predrag Spasojevic and Prof. Dipankar Raychaudhuri This thesis presents simulation and an experimental investigation of a decentralized spectrum allocation algorithm for secondary user co-existence in a cognitive radio network. Conventional centralized approaches ...

The economical and the environmental bene ̄ts of product remanufacturing have been widely recognized in the literature and in practice. In this paper, we focus on the interaction between a manufacturer's reverse channel choice to collect post-consumer goods and the strategic product pricing decisions in the forward channel when retailing is competitive. To this end, we model a centralized produc...

Currently, communication between nanomachines is an important topic for the development of novel devices. To implement a nanocommunication system, diffusion-based molecular communication is considered as a promising bio-inspired approach. Various technical issues about molecular communications, including channel capacity, noise and interference, and modulation and coding, have been studied in t...

Wireless operators, in developed or emerging regions, must support triple-play service offerings as demanded by the market or mandated by regulatory bodies through so-called Universal Service Obligations (USOs). Since individual operators might face different constraints such as available spectrum licenses, technologies, cost structures or a low energy footprint, the EU FP7 CARrier grade wirele...

multiagent systems, where the focus is to enable multiple agents to work together to solve a problem. These agents are often assumed to be cooperative, that is, they are part of a team or they are self-interested but incentives or disincentives have been applied such that the individual agent rewards are aligned with the team reward. We illustrate the motivations for distributed problem solving...

Device-to-Device (D2D) communications are expected to improve user experience and network efficiency. Cellular and underlaying D2D communications will share the same cellular spectrum, and radio resource allocation policies are hence necessary to avoid their mutual interference. Most of the proposed policies are centralized schemes, and the base station decides the allocated radio resources. Ce...

This paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. System engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (TCO...

Health systems around the world are grappling with the difficult issue of how to allocate scare healthcare resources. Within Europe many different approaches to healthcare resource allocation exist, but it is clear that the formal techniques of cost-effectiveness analysis are becoming increasingly important. This presentation will first address the fundamental economic principles of scarcity an...
