Context Information Management in the uOS middleware

From 19th to 22th of July the XXXI Brazilian Computer Society Congress (CSBC) has held in Natal (RN). Our project participated to the Brazilian Symposium of Ubiquitous Computing (SBCUP), one of the events of this Congress. 13 papers were accepted to SBCUP, which represents 35% of the total of papers submitted. Our accepted paper presents a model for context information management based on ontologies. Professor Dr. Hyggo Oliveira de Almeida from the Federal University of Campina Grande started the event by presenting an overview of context awareness state of art.

The Laboratory - LAICO

Since the foundation of the UnBiquitous Research Group in 2007 the LAICO laboratory was the place where our activities were done. LAICO stands for LAboratório de sistemas Integrados e COncorrente, which in english means Concurrent and Integrated Systems Laboratory. The laboratory is the house of many projects in the Department of Computer Science for the University of Brasilia including us.

Here were going to talk a little bit about the research Unbiquitous has been doing there.

Monthly we get together to talk about what each researcher is doing. We call it the uOS-Gathering. It's a very important moment to share information and knowledge. Here PHD candidates, graduates and undergrads sit together to discuss about what happened and what we intend to do.

The uOS middleware is now available in JSE and JME versions but we've been working to port it to other platforms. The Android is one of them. Smart Phones plays an important role nowadays making them a key player in order to achieve our users.

We don't limit ourselves to Android, but have also the intention to begin the porting to the iOS platform.

The Arduino is the platform chosen for testing the limits of our proposal. Since we aim in limited device, this Open Hardware solution suits well our needs.

At last, we have been working on applications for our platform. Among them we've been using the Kinect sensors to aid in locating and identifying users in the smart space.

Thats it. I hope you liked our laboratory and pay us a visit.

uMedia 2011 and the uP Protocol set

On this last weekend (3rd and 4th of july) was held the 4th International Conference on Ubi-media Computing (or just umedia) on the city of São Paulo, Brazil. Umedia accepted our paper about the uP protocol set and was represented by myself.

This was the first time that this conference took place outside Asia. There was more than 100 papers submitted and 34 were accepted, most of which were from China there was submissions from Switzerland, Germany, Taiwan, Australia, Portugal and Brazil (among others). The three keynotes presented different subjects related to each research field. Professor Timothy K. Sith, from National Central University at Taiwan, showed very interesting achievements in video forgery that associated with augmented reality places great advances in ubicomp. Professor Jo Ueyama, from University of São Paulo at Brazil, presented his achievements in using Wireless Sensors Networks in order to prevent floods. The last keynote. Claudio Pinhanez from IBM Research at Brazil, discussed about many topics related to ubicomp and defended his view of Ubiquitous Services as a different approach for ubicomp solutions.

The uP protocol set

Our paper was entitled "uP: A Lightweight Protocol for Services in Smart Spaces" and showed part of our research at the unbiquitous research group. This protocol set is part of a composite solution that involves the DSOA (Device Service Oriented Architecture) and the uOS middleware. The presentation can be seen as follows or here.
