open-LQE toolset released and publicly available at http://www.open-LQE.net/ The open-LQE website (http://www.open-LQE.net/) provides an open-source toolset for radio link quality estimation in wireless sensor networks (WSNs). Estimating the quality of radio links is of paramount importance in WSNs, namely for designing reliable and energy-efficient WSN protocols/mechanisms (e.g. MAC, routing, mobility management, fault-tolerance, deployment, and topology control). For instance, many routing protocols (e.g. CTP) rely on link quality estimation to select higher quality routes. Therefore, it is important to assess the performance of a link quality estimator (LQE) before selecting and integrating it into a particular network protocol/mechanism. The open-LQE web site includes the following open-source toolset: ********** RadiaLE ********** RadiaLE is a benchmarking test-bed that enables the performance evaluation of LQEs. It comprises the hardware components of the WSN test-bed (TelosB nodes, USB cables/hubs) and a software tool for setting up and controlling the experiments and also for analyzing the collected data, allowing for LQEs evaluation (more details are given in http://www.open-lqe.net/Overview.php). While we built up and validated RadiaLE through a test-bed setup in Porto (Portugal), the idea is that anyone can use it in their own location just by downloading and running the following applications: 1- Experiment Control Java application. It allows motes programming/control, network configuration and data logging into a MySQL database. 2- Data analysis MATLAB application. It processes the collected data to provide two main functionalities: link characterization and LQEs performance evaluation. ********** TinyOS implementation of several Link Quality Estimators ********** RadiaLE has a default set of LQEs already implemented (that can be easily extended with any other LQE), but these LQEs can also be used independently from RadiaLE. Therefore, we provide the nesC/TinyOS code for the following LQEs, as follows (tested under TOSSIM 2): 1- Implementation of 5 LQEs under TOSSIM 2, at CTP routing level: 4bit (the default LQE of CTP) ETX, RNP, PRR and WMEWMA. 1- Implementation of 6 LQEs under TOSSIM 2, at the Application level: F-LQE, 4bit, ETX, RNP, PRR and WMEWMA. The RadiaLE Team.

The TTX has been traditionally held in the USA. To foster a broader European TinyOS community, we are launching a companion event In Europe with the same format. The TinyOS Alliance Steering Committee encourages anyone who is interested in, using, exploring or advancing TinyOS-based technologies to attend. http://sites.google.com/site/ettx2009/

CONET meeting in Porto. The CONET Network of Excellence on "Cooperating Objects" is a EU-funded project under ICT/WP7, gathering a number of reputed European academic and industrial partners. The CONET project started on June 1st, 2008 and has a duration of 4 years, with a total funding of 4 MEuro. CONET tries to merge the areas of Embedded Systems, Pervasive Computing and Wireless Sensor Networks into what is dubbed "Cooperating Objects" systems. Several research clusters were triggered addressing complementary scientific topics, one of them quite related to the ART-WiSe/open-ZB frameworks - COTS4QoS (COTS-based Architecture for QoS in Large-Scale Distributed Embedded Systems), for which a first meeting was held in Porto, 19-20/NOV/2008. The objective of this cluster is to achieve Quality-of-Service in large-scale distributed embedded systems using standard and Commercial-Off-The-Shelf (COTS) hardware and software platforms (e.g. communication protocols, motes, operating systems). More info is available in http://www.cooperating-objects.eu/

Ricardo Severino defended his MSc in ECE with the Thesis entitled "On the use of IEEE 802.15.4/ZigBee for Time-Sensitive Wireless Sensor Network Applications", supervised by Prof. Mário Alves and co-supervised by Prof. Anis Koubaa. His contestor was Prof. José Alberto Fonseca, from the University of Aveiro. His final classification was 19 out of 20. The camera-ready version of the Thesis will be available for download soon.

ArtisDesign NoE kick-off meeting. Mário Alves participated in the kick-off meeting of the ArtistDesign European Network of Excellence (NoE) on the 2-3/OCT/2008, Pisa, Italy. ArtistDesign focuses on embedded systems design and involves a number of major academic and industrial players in the field (http://www.artist-embedded.org).

Mário Alves gave two Seminars in the a doctoral school for PhD students in Computer Science, in L'Aquila, Italy. Talk 1: "Enabling ubiquitous computing and cyber-physical systems with wireless sensor/actuator networks: what is at stake?". Talk 2: "Guaranteeing QoS in large-scale distributed embedded systems using standard and COTS technologies: ongoing research at IPP-HURRAY".

Prof. Peter Steenkiste (http://www.cs.cmu.edu/~prs/) came to Porto for meeting researchers at the IPP-HURRAY Research Group. Peter Steenkiste is a Professor of Computer Science and of Electrical and Computer Engineering at Carnegie Mellon University. A small workshop was organized so that Prof. Steenkiste could outline his ongoing research lines at CMU and learn about ours, to foster collaboration in the context of the Portugal-CMU programme (http://www.hurray.isep.ipp.pt/CMU-PT/). His research interests mostly concern wireless networking, in a broad range of wireless networking projects, such as self-managing chaotic networks, wireless testbed based on emulation, high-quality video over wireless and playing with software radios.

Ricardo Severino presented the paper entitled "ZigBee over TinyOS: implementation and experimental challenges" in the 8th Portuguese Conference on Automatic Control (CONTROLO’2008), Invited Session on "Real-Time Communications: from theory to applications", Vila Real, Portugal. This paper reports on our experience with TinyOS and with the MICAz and TelosB mote platforms, outlining some of the major difficulties we have encountered in the context of the implementation of our IEEE 802.15.4/ZigBee open-source stack.

Manish Batsa (maba@isep.ipp.pt) has joined the ART-WiSe team! Manish is a distinguished Indian undergraduate student (4th year, Computer Science and Engineering IIT Roorkee) that is doing an internship at IPP-HURRAY (until the end of July). He will work in the context of the ongoing project with SSSUP (Pisa) and will focus his work on developing the missing functionalities of our IEEE 802.15.4/ZigBee protocol stack over ERIKA.

The President of the Portuguese Republic, Prof. Aníbal Cavaco Silva, visited the CISTER Research Unit at ISEP. Among other cutting-edge research highlights, there was a focus on the new paradigms of large-scale distributed embedded systems for monitoring critical physical infrastructures (e.g. electrical, water, oil distribution networks, bridges, highways, tunnels). The ART-WiSe and open-ZB research frameworks were shortly overviewed, stressing on our belief that using standard communication protocols (as ZigBee) and commercial off-the-shelf technologies can speed-up a wider utilization of these wireless sensor network infrastructures. The Minister of Science and Technology, Prof. José Mariano Gago was also present, among other distinguished visitors.
