Response time analysis of slotted WiDom in noisy wireless channels
Vahabi, Maryam; Tennina, Stefano; Tovar, Eduardo; Andersson, BjörnWiDom is a wireless prioritized medium access control protocol which offers very large number of priority levels. Hence, it brings the potential to employ non-preemptive static-priority scheduling and schedulability analysis for a wireless channel assuming that the overhead of WiDom is modeled properly. Recent research has created a new version of WiDom (we call it: Slotted WiDom) which offers lower overhead co...
EMMON - EMbedded MONitoring
Santos, Manuel; Tennina, Stefano; Alves, Mário; Bouroche, Mélanie; Cahill, Vinny; Almeida, Délio; Carrozza, Gabriella; Hill, Alex; Chasapis, GeorgiosDespite the steady increase in experimental deployments, most of research work on WSNs has focused only on communication protocols and algorithms, with a clear lack of effective, feasible and usable system architectures, integrated in a modular platform able to address both functional and non–functional requirements. In this paper, we outline EMMON [1], a full WSN-based system architecture for large–scale, dens...
BANMAC: an opportunistic MAC protocol for reliable communications in body area ...
Prabh, K. Shashi; Royo, Fernando; Tennina, Stefano; Olivares, TeresaWe consider reliable communications in Body Area Networks (BAN), where a set of nodes placed on human body are connected using wireless links. In order to keep the Specific Absorption Rate (SAR) as low as possible for health safety reasons, these networks operate in low transmit power regime, which however, is known to be error prone. It has been observed that the fluctuations of the Received Signal Strength (R...
Building a microscope for the data center
Pereira, Nuno; Tennina, Stefano; Tovar, EduardoManaging the physical and compute infrastructure of a large data center is an embodiment of a Cyber-Physical System (CPS). The physical parameters of the data center (such as power, temperature, pressure, humidity) are tightly coupled with computations, even more so in upcoming data centers, where the location of workloads can vary substantially due, for example, to workloads being moved in a cloud infrastructu...
EMMON: a system architecture for large- scale, dense and real-time WSNs
Tennina, Stefano; Braga, Pedro; Alves, Mário; Ciriello, Vincenzo; Santos, Manuel; Cahill, Vinny; Bouroche, Mélanie; Gomes, Ricardo; Mirza, FarrukhIn spite of the significant amount of scientific work in Wireless Sensor Networks (WSNs), there is a clear lack of effective, feasible and usable WSN system architectures that address both functional and non-functional requirements in an integrated fashion. This poster abstract outlines the EMMON system architecture for large-scale, dense, real-time embedded monitoring. EMMON relies on a hierarchical network ar...

Tennina, Stefano; Bouroche, Mélanie; Santos, Manuel; Oliveira, Pedro; Gomes, Ricardo; Mirza, Farrukh; Ciriello, Vincenzo; Cahill, Vinny; Alves, MárioWireless sensor networks (WSNs) have attracted growing interest in the last decade as an infrastructure to support a diversity of ubiquitous computing and cyber-physical systems. However, most research work has focused on protocols or on specific applications. As a result, there remains a clear lack of effective and usable WSN system architectures that address both functional and non-functional requirements in ...

The dark side of DEMMON: what is behind the scene in engineering large-scale wi...
Tennina, Stefano; Gomes, Ricardo; Alves, Mário; Ciriello, Vincenzo; Carrozza, GabriellaMost research work on WSNs has focused on protocols or on specific applications. There is a clear lack of easy/ready-to-use WSN technologies and tools for planning, implementing, testing and commissioning WSN systems in an integrated fashion. While there exists a plethora of papers about network planning and deployment methodologies, to the best of our knowledge none of them helps the designer to match coverage...
