Z-Monitor: A protocol analyzer for IEEE 802.15.4-based low-power wireless networks
Tennina, Stefano; Gaddour, Olfa; Koubaa, Anis; Royo, Fernando; Alves, Mário; Abid, MahomedNetwork sniffers are invaluable tools for designing, testing, commissioning and running distributed embedded systems. They become even more useful if these systems build on low-power wireless networks (LoWPAN), particularly when these scale in density and/or space and impose stringent quality-of-service requirements. This paper presents Z-Monitor, a low-cost and open-source network/protocol analyzer for LoWPANs...
Experimental study of the stress level at the workplace using an smart testbed ...
Silva, Fábio; Olivares, Teresa; Royo, Fernando; Vergara, M. A.; Analide, CésarThis paper combines techniques of ambient intelligence and wireless sensor networks with the objective of obtain important conclusions to increase the quality of life of people. In particular, we oriented our study to the stress at the workplace, because stress is a leading cause of illness and disease. This article presents a wireless sensor network obtaining information of the environment, a pulse sensor obta...
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...
