Energy efficiency is one of leading design principles for the current deployment of cellular mobile networks. A first driving reason for this is that half of the operating costs for the network providers comes from the energy spent to power the network, with almost 80% of it being consumed at the base stations. A second reason is related to the high environmental pollution, which makes the gree...

Keyword advertising, or “sponsored links” that appear alongside online search results or other online content, has grown into a multibillion-dollar market. Providers of keyword advertising, such as Google and Yahoo, profit by auctioning keywords to advertisers. An issue of increasing importance for advertising providers is the “share structure” problem—that is, of the total available resources ...

This report presents a novel game-theoretical framework to model the evolution of spectrum markets that consists of multiple spectrum/network operators that provide wireless access to users. It integrates models about the channel, mobility, user preference, network operators (providers), infrastructure deployment, user distribution, and price-adaptation mechanisms. Providers aim to maximize the...

Northeastern British Columbia, Canada, is undergoing in-migration of young people attracted by jobs in the oil/gas sectors. Chlamydia rates among youth ages 15-24 are increasing and exceed the provincial average by 22%. Testing for sexually transmitted infections (STIs) reduces the disease burden, contributing to prevention. We conducted ethnographic fieldwork, including interviews with 25 yout...

The trend to outsourcing network services to third parties in a utility model has resulted in a new distributed application model where the hosting service, service providers and end clients constitute a co-dependent profit ecosystem. SLAs provide a means for the service providers to specify their target levels of performance and reliability and for the hosting service to arbitrate among compet...

Cloud computing has recently emerged as one of the buzzwords in the IT industry. Several IT vendors are promising to offer computation, data/storage, and application hosting services, offering Service-Level Agreements (SLA) backed performance and uptime promises for their services. While these „clouds‟ are the natural evolution of traditional clusters and data centers, they are distinguished by...

One of the important debates in service-oriented architecture is the competitive conditions in the side of service provider and service consumer. In service-oriented architecture environment, different service consumers are trying to obtain their required service for which they compete with other service applicants. On the other hand different service providers are competing with each other to ...

This paper studies an incentive structure for cooperation and its stability in peer-assisted services when there exists multiple content providers, using a coalition game theoretic approach. We first consider a generalized coalition structure consisting of multiple providers with many assisting peers, where peers assist providers to reduce the operational cost in content distribution. To distri...

In order to improve the financial processing effect of supply chain integrated business intelligence, this study applies blockchain technology intelligence and conducts an evolutionary game analysis on factors that affect selection information-sharing strategies for logistic service nodes. By establishing model integrators providers under strategy information sharing nonsharing, value in is dis...

We propose a computational model to study (the evolution of) post-secondary education.“Consumers” that differ in quality shop around for desirable colleges or universities. “Firms” that differ in quality signal the availability of their services to desirable students. Colleges and universities, as long as they have capacity, make offers to students that apply and qualify. We study the dynamics ...
