Best compromise solution for a new multiobjective scheduling problem
2006
In future wireless networks, a mobile terminal will be able to communicate with a service provider using several network connections. These connections to networks will have different properties and they will be priced separately. In order to minimize the total communication time and the total transmission costs, an automatic method for selecting the network connections is needed. Here, we describe the network connection selection problem and formulate it mathematically. We discuss solving the problem and analyse different multiobjective optimization approaches for it.
Revenue-based adaptive deficit round robin
2005
This paper presents an adaptive resource allocation model that is based on the DRR queuing policy. The model ensures QoS requirements and tries to maximize a service provider's revenue by manipulating quantum values of the DRR scheduler. To calculate quantum values, it is proposed to use the revenue criterion that controls the allocation of free resources. The simulation considers a single node with the implemented model that serves several service classes with different QoS requirements and traffic characteristics. It is shown that the total revenue can be increased due to the allocation of unused resources to more expensive service classes. At the same time, bandwidth and delay guarantees…
Product and service bundling decisions and their effects on purchase intention
1997
Examines the effects of four factors (the bundle: pure or mixed, the price discount, the functional complementarity of bundle components, and the number of bundle components) on consumers’ intentions to purchase product and service bundles. The findings were relatively consistent across product (automobile) and service (automotive service) contexts, and illustrate that pure bundles are preferred to mixed bundles, and a greater price discount is preferred to a lesser one. The results also indicate that five component bundles generate greater purchase intention than either three or seven component bundles, and that “very related” bundle components result in greater purchase intention than eit…
Multihoming in the Market for Payment Media: Evidence from Young Finnish Consumers
2004
Tassa tutkimuksessa tarkastellaan sita, miksi jotkut kuluttajista kayttavat vain yhta maksuvalinetta ja toiset kuluttajat monia maksuvalineita maksaessaan paivittaisia ostoksiaan. Kayttamalla aineistoa nuorista suomalaisista kuluttajista loydamme, etta yksi tarkeimmista maksuvalineiden kayttoon vaikuttavista tekijoista on kuluttajien yleinen tietoisuus maksamiseen liittyvista kysymyksista. Instrumenttimuuttujaestimoinnit osoittavat, etta paremmin tietoiset kuluttajat kayttavat 1.2-1.3 kertaa useampaa maksuvalinetta kuin vahemman tietoiset kuluttajat. Koska monia uusia maksuvalineita kaytetaan usein aluksi olemassa olevien maksuvalineiden rinnalla, tuloksemme tukevat nakemysta, etta kuluttaj…
A secret sharing scheme for anonymous DNS queries
2013
Since its adoption in the early 90's, several privacy concerns have emerged about the Domain Name System (DNS). By collecting the DNS queries performed by each user, it is possible to characterize habits, interests and other sensitive data of the users. Usually, users resolve their {\em url} requests by querying the DSN server belonging to their Internet Service Provider (ISP) and therefore they assume they can trust it. However, different DNS servers can be used, by revealing sensitive data to a partially untrusted entity that can collect and sell this data for several purposes (target advertising, user profiling, etc.). In this paper we address the possibility to integrate tools in the cu…
Tuning of QoS Aware Load Balancing Algorithm (QoS–LB) for Highly Loaded Server Clusters
2001
This paper introduces a novel algorithm for content based switching. A content based scheduling algorithm (QoS Aware Load Balancing Algorithm, QoS-LB) which can be used at the front-end of the server cluster is presented. The front-end switch uses the content information of the requests and the load on the back servers to choose the server to handle each request. At the same time, different Quality of Service (QoS) classes of the customers can be considered as one parameter in the load balancing algorithm. This novel feature becomes more important when service providers begin to offer the same services for customers with different priorities.
Energy Efficiency Evaluation of Cellular Networks Based on Spatial Distributions of Traffic Load and Power Consumption
2013
Energy efficiency has gained its significance when service providers' operational costs burden with the rapidly growing data traffic demand in cellular networks. In this paper, we propose an energy efficiency model for Poisson-Voronoi tessellation (PVT) cellular networks considering spatial distributions of traffic load and power consumption. The spatial distributions of traffic load and power consumption are derived for a typical PVT cell, and can be directly extended to the whole PVT cellular network based on the Palm theory. Furthermore, the energy efficiency of PVT cellular networks is evaluated by taking into account traffic load characteristics, wireless channel effects and interferen…
Probabilistic Fuzzy Approach to Evaluation of Logistics Service Effectiveness
2014
Received: 9 September 2014 Abstract Accepted: 11 October 2014 Logistics service providers offer a whole or partial logistics business service over a certain time period. Between such companies, the effectiveness of specific logistics services can vary. Logistics service providers seek the effective performance of logistics service. The purpose of this paper is to present a new approach for the evaluation of logistics service effectiveness, along with a specific computer system implementing the proposed approach – a sophisticated inference system, an extension of the Mamdani probabilistic fuzzy system. The paper presents specific knowledge concerning the relationships between effectiveness i…
Mobile Banking and Payment System : A Conceptual Standpoint
2017
This study conceptualizes and proposes a well-regulated and designated mobile banking and payment system (MBPS) with the potential to strengthen the banking system, foster the regulatory framework, and to be integrated across various platforms and mobile devices. Unlike other mobile payment systems that lack convenience, scalability, and usability, the proposed MBPS contains several important functionalities and it has the potential to bring together hitherto unconnected industries—banking, Fintech and telecoms—to offer value-added services to their existing and potential customers. The ownership of the MBPS shall remain with the financial services sector including the banking and microfina…
Introduction to Software Product Lines: Engineering, Services, and Management Minitrack
2013
Software has become the key asset for competitive products and services in all industries. Thus, competiti¬veness in software development, maintenance, and related ser¬vices has become a concern for organiza¬tions. Competitiveness can be increased through (1) internal strategies such as the strategic crea¬tion and reuse of softwa¬re assets and (2) external strategies such as outsourcing software de¬velopment, maintenance, and/or services from third party service providers and acquiring off-the-shelf components from providers and open source communities. A viable third strategy is to enact both strategies in parallel. This minitrack focuses on the first and third strategy. The minitrack acce…
