Abstract
While Cluster-Tree network topologies look promising for WSN applications with timeliness and energy-efficiency requirements, we are yet to witness its adoption in commercial and academic solutions. One of the arguments that hinder the use of these topologies concerns the lack of flexibility in adapting to changes in the network, such as in traffic flows. This paper presents a solution to provide these networks with the ability to self-adapt to different bandwidth and latency requirements, imposed by traffic flows, by changing the cluster's duty-cycle and scheduling. Importantly, our approach enables a network to change its cluster scheduling without requiring long inaccessibility times or the re-association of the nodes. We show how to apply our methodology to the case of IEEE 802.15.4/ZigBee cluster-tree WSNs without significant changes to the protocol. Finally, we analyze and demonstrate the validity of our methodology through a comprehensive simulation and experimental validation using commercially available technology on a Structural Health Monitoring application scenario.

A method for the development of Dublin core application profiles (me4dcap v0.2): Detailed description

Proceedings of the International Conference on Dublin Core and Metadata Applications

Abstract
Our research in progress project aims the design of a method for the development of Dublin Core Application Profiles (Me4DCAP). This paper describes Me4DCAP V0.2, an early version of a method for the development of DCAP. The development of Me4DCAP was based on a Design Science Research methodological approach and has as starting points the Singapore framework for DCAP and the Rational Unified Process; integrates knowledge from: (i) the practices of the metadata community concerning DCAP development, and (ii) software development processes and techniques, focusing on the early stages of the processes that deal with data modeling. Me4DCAP establishes a way for the development of a DCAP. It establishes which are the activities, when they should take place, how they interconnect, and which deliverables they will bring about; it also suggests which techniques should be used to build these deliverables. © DCMI 2013.

Me4DCAP V0.1: A method for the development of Dublin core application profiles

Abstract
Recent studies show that there is no method to develop a Dublin Core Application Profile (DCAP). A DCAP is a very important construct to implement interoperability, therefore it is essential to have a method to be able to develop such a construct, in order to give DCAP developers a common ground of work. This paper presents the first version of a method to develop Dublin Core Application Profiles (Me4DACP V0.1) that has been developed in a PhD project with a Design Science Research (DSR) approach. Me4DCAP was built having as starting point the Singapore Framework for DCAP and shows the way through the DCAP development. It encompasses a group of pre-defined interconnected activities, explicitly states when they should take place, what techniques could be used to execute them and what artifacts should result from their execution. © 2013 The authors and IOS Press.

State of the art on methodologies for the development of a metadata application profile

Abstract
This paper presents the state of the art on methods for the development of a metadata application profile (AP). For this purpose we perform searches in scientific online databases and made other efforts such as global searches on the web and calls on the mailing lists of the metadata communities to find information about AP development and metadata best practices or methods for the development of AP. These searches produced 21 items of which nine have information on how the AP is developed. As a result of this analysis, we came up with small formulas or specific recipes for very particular phases of the process, but none is described in detail. We have also come up with guidelines that were too global and not sufficiently detailed for the AP development. As far as we could determine, there is no comprehensive methodological support for a metadata application profile development. Copyright © 2013 Inderscience Enterprises Ltd.

Interviews to Dublin Core Application Profiles developers

Autores
Malta, Mariana Curado;

Publicação

Abstract
These files are the recordings and transcripts of 3 interviews made to 3 Dublin Core Application Profiles developers with the aim to understand the process of a DCAP development. These interviews are framed in a PhD project that has as goal the definition of a method for the development of Dublin Core Aplication Profiles. An Application Profile is a construct on the Semantic Web that enhances interoperability.
