![]() Underlying identification technology such as bar codes or RFID?", "How mustĪn identifier be structured?", "Which kind of location model isĪppropriate?", "How does the service infrastructure realize the couplingīetween a thing and its representation?", "Which other services can be ![]() Model, the following problem areas and questions arose that are also addressedīy the model: "How can we abstract from the implementation details of the Throughout this work, the model serves to formulate the problems andĬhallenges of an implementation of such systems precisely, so that the modelĬan be used as a template for future implementation. Besides the definition of the vocabulary that is used These four concepts and their relative dependencies will beĮxpanded and presented. Service infrastructure} that allows for the coupling of the tag and its Model differentiates between four concepts: a thing, the tag attached to itįor identification, a representation of that thing in IT systems, and a Objects automatically, such as bar code or RFID systems.Īfter these preparations, the fourth chapter introduces a model thatĭescribes a world of collaborating everyday items. Web Services, and hardware systems, on the other hand, that serve to identify The one hand, that support dynamic client/server applications, such as Jini or Systems considered in this work are based. In the third chapter, the technologies are presented on which the smart thing Substantially better way than would be possible with current means. It is theĪssumption of this dissertation that the concepts and systems presented hereĭescribe and support a world of collaborating everyday items in a Services that extract and execute application-independent tasks. In terms of a generic class library and, on the other hand, middleware Understand a software system that comprises, on the one hand, a softwareįramework that provides application developers with the required abstractions Systems that aim at realizing a world of smart everyday items. At first, these economic applications serve, especially the supplyĬhain application, to enumerate the requirements that need to be fulfilled by ItĬonsists of a supply chain application with several participants that exchange Will be referenced throughout this work, will be discussed more deeply. Introduced in the following second chapter. Starting from these visions, economically practicable applications will be Ubiquitous computing, which was first formulated by its pioneer Marc Weiser. In the introductory first chapter of this work, this vision will be extendedĪnd it will be shown how it can be embedded in the more general vision of Management systems of supply chain participants, so that they know exactly Another task that a bottle might take over is lessĬomplex and more cost efficient: it signs in and off at the warehouse The temperature and if a certain limit is exceeded, the bottle can send anĪlarm message and if its own temperature sensor is broken, it simply asks aīottle in its vicinity. ForĮxample, a bottle that contains temperature sensitive chemicals can monitor Their environment, and are able to communicate with other smart things. Smart everyday items differįrom regular everyday items insofar as they know their whereabouts, perceive Vision of a world with "smart" everyday items. The goal of this dissertation is to contribute towards the realization of the
