A Location-Aware Waypoint-Based Routing Protocol for Airborne DTNs in Search and Rescue Scenarios

Bujari, Armir; Tavares De Araujo Cesariny Calafate, Carlos Miguel; Cano, Juan-Carlos; Manzoni, Pietro; Palazzi, Claudio; Ronzani, Daniele (MDPI AG, 2018)

[EN] In this paper, we propose GeoSaW, a delay-tolerant routing protocol for Airborne Networks in Search and Rescue scenarios. The protocol exploits the geographical information of UAVs to make appropriate message forwarding ...
Cooperation techniques to improve peer-to-peer wireless networks security

Serrat Olmos, Manuel David (Editorial Universitat Politècnica de València, 2013-10-15)

Computer networks security is a topic which has been extensively researched. This research is fully justified when one notices the dimensions of the problem faced. One can easily identify different kinds of networks, a ...
Delay Tolerant Networks for Efficient Information Harvesting and Distribution in Intelligent Transportation Systems

Martínez Tornell, Sergio (Universitat Politècnica de València, 2016-09-01)

[EN] Intelligent Transportation Systems (ITS) can make transportation safer, more efficient, and more sustainable by applying various information and communication technologies. One of these technologies are \acfp{VN}. ...
Epidgeons: Combining Drones and DTNs Technologies to Provide Connectivity in Remote Areas

Manzoni, Pietro; Tavares de Araujo Cesariny Calafate, Carlos Miguel; Cano Escribá, Juan Carlos; Mota, Edjair (ACM Digital Library, 2015-05-19)

In certain geographical areas such as the rural areas or the developing regions, the lack of infrastructure, the temporary nature of the connections and the limited access to fixed public networks does not allow the use ...
Evaluación y Modelado de Redes Oportunistas

Chancay Garcia, Leonardo Javier (Universitat Politècnica de València, 2019-07-29)

[ES] La disponibilidad y el rendimiento de las actuales tecnologías inalámbricas como WiFi o 4G, pueden tener serios problemas de congestión y propagación, especialmente en espacios muy concurridos, o bien ser inaccesibles ...
FloatingBlue: A Delay Tolerant Networks-Enabled Internet of Things Architecture for Remote Areas Combining Data Mules and Low Power Communications

Teixeira, Ruan C. M.; Carvalho, Celso B.; Tavares De Araujo Cesariny Calafate, Carlos Miguel; Mota, Edjair; Fernandes, Rubens A.; Printes, Andre L.; Nascimento, Lennon B. F. (MDPI AG, 2024-10)

[EN] Monitoring vast and remote areas like forests using Wireless Sensor Networks (WSNs) presents significant challenges, such as limited energy resources and signal attenuation over long distances due to natural obstacles. ...
Improving Message Delivery Performance in Opportunistic Networks using a Forced-stop diffusion scheme

HERRERA TAPIA, JORGE; Hernández Orallo, Enrique; Tomás Domínguez, Andrés Enrique; Manzoni, Pietro; Tavares de Araujo Cesariny Calafate, Carlos Miguel; Cano Escribá, Juan Carlos (Springer, 2016-07)

The performance of mobile opportunistic networks strongly depends on contact duration. If the contact lasts less than the required transmission times, some messages will not get delivered, and the whole diffusion scheme ...
