Benefits through Utilising EPC Network Components in ServiceāOriented Environments ā an Analysis Using the Example of the Food Industry
Improvements in the food sector imply enhancements of delivering food which is safe, affordable, readily available, and of the quality and diversity consumers expect. However, prevalent information systems (IS) of companies in the food industry are not ready to support further significant improvements. They especially lack the capability to exchange relevant information in an efficient manner. Since recently, two major developments can be observed from IS perspective: the spreading of service-oriented architectures (SOA) as well as an increase in mass serialization (due to public and private traceability requirements, e.g.). So far, though most important due to food safety, a growing need to become more efficient as well as an increasing information demand of consumers, the food sector has attracted little attention in literature concerning an analysis about the potential of both service-orientation and the Electronic Product Code (EPC) Network. This is why this paper will investigate to which extent these two developments can contribute to facilitate food companiesā IS helping them to maintain their competiveness. As a starting point, the research paper will depict the state of the art including SOA and the EPC Network. After describing the research approach, it will proceed with a characterisation of the food sector including an examination why there is need for action. Based on current research findings as well as experience gathered in recent projects, the paper will investigate the application of the EPC Network with its three major components, i.Ā e. EPCIS (EPC Information Services), ONS (Object Name Service) and the EPC Discovery Services, as part of future IS architectures in this sector. The paper will close with a discussion whether the envisioned IS architecture is appropriate to accomplish the previously identified challenges and requirements in the food sector in a more agile, efficient and effective way. What is more, it will highlight the most pressing challenges and provide an outlook as to the following steps of the research
Valuation of online social networks - An economic model and its application using the case of Xing.com
Ubiquitous information technologies like RFID allow for immediate, extensive and fine-grained
capture of real world information. Scalable and efficient networks for exchange of this vast amount of
information amongst companies are crucial for the economic exploitation of benefits of ubiquitous
information technologies. Existing networks bear several limitations like risks of single-point-offailures or bottlenecks, unequally distributed power and burdens as well as inflexibility through
stringent structures and formats. In particular there is a need for improving the scalability of solutions
and ensuring autonomy of network participants. In this paper we introduce a Peer-to-Peer-based
architecture for exchanging distributed information, which are shared among participants of a supply
chain facilitated with ubiquitous information technologies. This architecture builds on the wellestablished EPCglobal standards, but can be implemented as an autonomous network. Unlike other
architectures it does not need central coordination mechanisms, because it is based on self-organizing
Peer-to-Peer protocols. We argue that our architecture supports business processes especially of
small and medium-sized enterprises better than other architectures. We provide a discussion about
requirements for solutions and a simulation-based analysis of the proposed architecture
Informacijski servisni sustav za poljoprivredni IoT
Internet of Things (IoT) was faced with some difficulties which contained mass data management, various standards of object identification, data fusion of multiple sources, business data management and information service providing. In China, some safety monitoring systems of agricultural product always adopt centralized system architecture in which the data is stored concentratively. These systems could not be connected with or accessed by each other. This paper proposed an information system of agriculture Internet of Things based on distributed architecture. A distributed information service system based on IoT-Information Service, Object Naming Service, Discovery Service is designed to provide public information service including of capturing, standardizing, managing and querying of massive business data of agriculture production. A coding scheme for agricultural product, business location and logistic unit is provided for data identification. A business event model of agriculture IoT is presented for business data management. The whole system realizes the tracking and tracing of agricultural products, and quality monitoring of agriculture production. The implementation of this information service system is introduced.Internet stvari suoÄen je s poteÅ”koÄama poput upravljanja s velikom koliÄinom podataka, razliÄitim standardnima identifikacije objekata, fuzije podataka iz viÅ”e izvora, upravljanja poslovnim podatcima i pružanje informacijskih usluga. Sigurnosno nadgledanje poljoprivrednih proizvoda u Kini uvijek podliježe centraliziranoj arhitekturi gdje su podatci koncentrirani na jednom mjestu. Takvi sustavi ne mogu biti povezani jedni s drugim te jedan drugome ne mogu pristupati. U ovome radu predložen je informacijski sustav za poljoprivredni internet stvari temeljen na distribuiranoj arhitekturi. Distribuirani informacijski servisni sustav baziran na IoT (Internet stvari), sustav za imenovanje objekata i sustav za otkrivanje omoguÄuju javni informacijski servis ukljuÄujuÄi prikupljanje, standardizaciju, upravljanje i ispitivanje velikih koliÄina podataka o poljoprivrednim proizvodima. Prikazana je shema kodiranja za poljopoprivredne proizvode, poslovne lokacije i logistiÄke jedinice za identifikaciju podataka. Poslovni model doga.aja za poljoprivredni IoT je prezentiran za upravljanje poslovnim podatcima. Cjelokupni sustav omoguÄuje praÄenje poljoprivrednih proizvoda te nadgledanje njihove kvalitete. Rad tako.er daje uvid u implementaciju informacijskog servisnog sustava
Internet of Things Strategic Research Roadmap
Internet of Things (IoT) is an integrated part of Future Internet including existing and evolving Internet and network developments and could be conceptually defined as a dynamic global network infrastructure with self configuring capabilities based on standard and interoperable communication protocols where physical and virtual āthingsā have identities, physical attributes, and virtual personalities, use intelligent interfaces, and are seamlessly integrated into the information network
When Things Matter: A Data-Centric View of the Internet of Things
With the recent advances in radio-frequency identification (RFID), low-cost
wireless sensor devices, and Web technologies, the Internet of Things (IoT)
approach has gained momentum in connecting everyday objects to the Internet and
facilitating machine-to-human and machine-to-machine communication with the
physical world. While IoT offers the capability to connect and integrate both
digital and physical entities, enabling a whole new class of applications and
services, several significant challenges need to be addressed before these
applications and services can be fully realized. A fundamental challenge
centers around managing IoT data, typically produced in dynamic and volatile
environments, which is not only extremely large in scale and volume, but also
noisy, and continuous. This article surveys the main techniques and
state-of-the-art research efforts in IoT from data-centric perspectives,
including data stream processing, data storage models, complex event
processing, and searching in IoT. Open research issues for IoT data management
are also discussed
Impliance: A Next Generation Information Management Appliance
ably successful in building a large market and adapting to the changes of the
last three decades, its impact on the broader market of information management
is surprisingly limited. If we were to design an information management system
from scratch, based upon today's requirements and hardware capabilities, would
it look anything like today's database systems?" In this paper, we introduce
Impliance, a next-generation information management system consisting of
hardware and software components integrated to form an easy-to-administer
appliance that can store, retrieve, and analyze all types of structured,
semi-structured, and unstructured information. We first summarize the trends
that will shape information management for the foreseeable future. Those trends
imply three major requirements for Impliance: (1) to be able to store, manage,
and uniformly query all data, not just structured records; (2) to be able to
scale out as the volume of this data grows; and (3) to be simple and robust in
operation. We then describe four key ideas that are uniquely combined in
Impliance to address these requirements, namely the ideas of: (a) integrating
software and off-the-shelf hardware into a generic information appliance; (b)
automatically discovering, organizing, and managing all data - unstructured as
well as structured - in a uniform way; (c) achieving scale-out by exploiting
simple, massive parallel processing, and (d) virtualizing compute and storage
resources to unify, simplify, and streamline the management of Impliance.
Impliance is an ambitious, long-term effort to define simpler, more robust, and
more scalable information systems for tomorrow's enterprises.Comment: This article is published under a Creative Commons License Agreement
