The huge number of Web Things (WoT) services make their discovery a real challenge. One strategy to deal with this challenge is reduce, as much possible, the discovered using different mechanisms such semantic Web-based clustering. However, most existing approaches are better suitable for static context and don't consider dynamicity gateways. Moreover, them centralized approaches. In paper we propose distributed WoT architecture. Our architecture leverages three filtering mechanisms:...

The context-awareness management is a challenging task in distributed collaborative environment. This implies the monitoring of context information users while adapting responses their requests according to context. In this work, we distribute adaptation among several entities by adopting mobile agent paradigm. leads solution for management. tackled using decision tree-based approach. A context-aware selection algorithm given select appropriate terminal where tasks will be made. An e-health...

Distributed applications in a heterogeneous environment (heterogeoous wireless and mobile networks, heterogenous middlewares operating systems, etc.) require facilities for context adaptation especially when users are collaborating through this environment. In work the is considered as set of rules on following parameters: connectivity, user availability location. These anticipate changes that may occur parameters order to provide an adaptable service. A decision tree-based approach used...

Developing1 accurate entity linking systems is essential for the semantic annotation of Web Things data. The Entity (EL) task aims at a piece data called mention from source document to it represents in knowledge base. Since could refer different entities, disambiguation step should be performed leveraging some features. In general, Three types features considered: (1) context-independent which rely basically on surface form and candidate (2) local context-dependent take into consideration...

The web of things (WoT) improves syntactic interoperability between internet (IoT) devices by leveraging standards. However, the lack a unified WoT data model remains challenge for semantic interoperability. Fortunately, technologies are taking this over offering numerous vocabularies like sensor networks (SSN) ontology. Although it enables heterogeneous devices, manual annotation hinders scalability WoT. As result, automation becomes prior issue researchers. This paper proposes method to...

The face tracking techniques are derived from the "radarists", who based on theory of estimation.Motion estimation in image sequences is an important step many computer vision and processing applications. Several methods for solving this problem have been proposed, but very few manage to achieve a high level accuracy without sacrificing speed. This paper describes new algorithm video hierarchical motion models. We demonstrate real-world videos order speed.1

The deployment of interoperability, mobility, security and scalability mechanisms is essential for IoT.While, these are resources consumers, IoT devices constrained.This dilemma requires the use an architecture capable meeting compute storage needs while remaining close to data sources.In this article, we propose a distributed based on Fog computing.This does not marginalize cloud edge computing.But, tries balance role each paradigm according resource dictated by challenges.Besides, indexing...
