The fresh products supply chain still has room to improve and increase efficiency and even become an intelligent supply chain by means of automating simple but valuable data flows which will be the foundations and first stage for developing new value-added services. The Spanish company ECOMOVISTAND has developed an innovative and ecological packaging and(More)
In order to perform sensing tasks, most current Intelligent Transportation Systems (ITS) rely on expensive sensors, which offer only limited functionality. A more recent trend consists of using Wireless Sensor Networks (WSN) for such purpose, which reduces the required investment and enables the development of new collaborative and intelligent applications(More)
The Smart Grid (SG) is conceived as the evolution of the current electrical grid representing a big leap in terms of efficiency, reliability and flexibility compared to today's electrical network. To achieve this goal, the Wireless Sensor Networks (WSNs) are considered by the scientific/engineering community to be one of the most suitable technologies to(More)
Wireless Sensor Networks (WSNs) are being deployed in very diverse application scenarios, including rural and forest environments. In these particular contexts, specimen protection and conservation is a challenge, especially in natural reserves, dangerous locations or hot spots of these reserves (i.e., roads, railways, and other civil infrastructures). This(More)
This paper proposes a general wireless sensor network architecture for monitoring horticultural crops that are distributed among small plots scattered at distances of up to 10 km from one another. The technology used for the real implementation of the architecture is based on the B-MAC (Berkeley Medium Access Control) medium access protocol to assure a high(More)
The extension of the network lifetime of Wireless Sensor Networks (WSN) is an important issue that has not been appropriately solved yet. This paper addresses this concern and proposes some techniques to plan an arbitrary WSN. To this end, we suggest a hierarchical network architecture, similar to realistic scenarios, where nodes with renewable energy(More)
IEEE 802.15.4 is a wireless technology aimed at the transmission of information at low rates and short distances. Therefore, the expected traffic carried by these networks is one whose transmission rates are low, i.e. information captured by sensors. The extension of this technology to higher data rates is a challenge that gives us the opportunity to(More)
Finding a complete mesh-based solution for low-rate wireless personal area networks (LR-WPANs) is still an open issue. To cope with this concern, different competing approaches have emerged in the Wireless Mesh Sensor Networks (WMSNs) field in the last few years. They are usually supported by the IEEE 802.15.4 standard, the most commonly adopted LR-WPAN(More)
Data organization has become a strategic target for biologists due to the increasing volume of genomic data available for them. For this purpose, we need a complete knowledge model for representing biological system. In this paper, we deal with both processes for the creation and integration of shareable, reusable domain models within biology, which is a(More)
Over the last few years, the research community has devoted great attention to video transmission on wireless sensor networks, and in particular to their recent evolution, the one based on IEEE 802.15.4 standard. This cost-efficient wireless technology is aimed at transmitting information at low rates and short distances. Extending the use of this(More)
