Ubiquitous Service Discovery using TRIP
نویسندگان
چکیده
We are investigating printed symbols as a tangible representation of Web services, to allow mobile users to identify and interact with local services available in (foreign) pervasive environments. We have extended the TRIP symbol recognition algorithm to allow larger address spaces for this purpose, and have implemented a prototype on a desktop computer. We present the results of testing recognition performance using 51 bits per symbol, varying the symbol size, orientation and distance from the camera. We show that these extended TRIP symbols are a feasible tangible representation for Web services in ubiquitous environments.

متن کاملUbiQuest: A P2P-based Resource Discovery System for Ubiquitous Computing*
Users in ubiquitous computing environments need to find and utilize ambient resources (ubiquitous services or devices which provide ubiquitous services). In ubiquitous computing, users and resources are highly mobile, and furthermore, the attributes of ubiquitous resources may change dynamically; the static/centralized resource management systems such as conventional DNS are inappropriate for u...
متن کاملSOA-based Service Layering for Facilitating Dynamic Service Composition and Alternative Service Discovery
ion for ubiquitous computing. The key to service modeling of SOA-based systems is in classifying services into business, application, and orchestration layers. However, service modeling techniques for SOA cannot be directly applied to a ubiquitous computing environment, which is dynamic, autonomous, and largely affected by run-time context. We have mainly focused on establishing the service lay...
متن کاملSemantic Based Service Discovery in Ubiquitous Computing
We propose a modification to the Service Discovery Protocol in Bluetooth in a mobile environment where devices like PDAs, cell phones or laptops communicate together, to provide and share various services. Within the environment, resources discovery is performed exploiting technologies and techniques for knowledge representation developed for the Semantic Web, which have been adapted to cope wi...
متن کاملA Semantic Service Discovery Network for Large - Scale Ubiquitous Computing Environments
Saehoon Kang et al. 545 This paper presents an efficient semantic service discovery scheme called UbiSearch for a large-scale ubiquitous computing environment. A semantic service discovery network in the semantic vector space is proposed where services that are semantically close to each other are mapped to nearby positions so that the similar services are registered in a cluster of resolvers. ...
