Heuristic methods in geographical routing protocols for VANETs
(Association for Computing Machinery (ACM), 2015)
Text en actes de congrés
Accés restringit per política de l'editorialThis paper proposes different local\hyph search heuristics to improve the performance of geographical routing protocols in VANET networks, which typically relies the selection of the next node only on the best candidate. ... -
Impact of packet error modeling in VANET simulations
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialSimulation is a very valuable mechanism to study the performance of vehicular ad-hoc networks (VANETs), due to the high cost and effort involved in the deployment of vehicles in urban scenarios. Accordingly, as in real ... -

MAX-MIN based buffer allocation for VANETs
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialMany proposals have studied the optimization of the EDCA mechanism used by the IEEE 802.11p MAC layer to provide QoS. In this work, we focus on the queuing process done by the different Access Categories (ACs). We propose ... -
On collaborative anonymous communications in lossy networks
(2013-05-17)
Article
Accés restringit per política de l'editorialMessage encryption does not prevent eavesdroppers from unveiling who is communicating with whom, when, or how frequently, a privacy risk wireless networks are particularly vulnerable to. The Crowds protocol, a well-established ... -
On the impact of building attenuation models in urban VANET simulations
(2015-01-08)
Article
Accés obertBuildings are important elements of cities for VANETs, since these obstacles may attenuate communications between vehicles. Consequently, the impact of buildings has to be considered as part of the attenuation model in ... -
Optimized path selection in a game-theoretic routing protocol for video-streaming services over MANETs
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialMobile ad hoc networks (MANETs) are infrastructureless networks formed by wireless mobile devices. Recently, the demand over multimedia services such as video streaming has increased specially since the number of mobile ... -
Performance evaluation of a hybrid sensor and vehicular network to improve road safety
(2010)
Text en actes de congrés
Accés obertIn the last years, wireless networks have become a widely spread type of communication technology and also a challenging scientific area for new fields of research. Many contributions in ad hoc networks, such as WSNs ... -
Propagation and packet error models in VANET simulations
(2014-05-01)
Article
Accés restringit per política de l'editorialIn this paper, we review the workflow of the channel and physical layer modules in VANET simulations and briefly survey some of the most used propagation and packet error models in network simulators for this kind of ... -
Realistic environment for VANET simulations to detect the presence of obstacles in Vehicular Ad Hoc Networks
(Association for Computing Machinery (ACM), 2014)
Comunicació de congrés
Accés restringit per política de l'editorialObstacles in Vehicular ad hoc networks (VANETs) in urban scenarios are an important issue. Normally, in traffic simulators vehicles can send/receive packets between each other if they are in the same transmission range no ... -
Reducing duplicate packets in unicast VANET communications
(Association for Computing Machinery (ACM), 2015)
Comunicació de congrés
Accés restringit per política de l'editorialIn vehicular networks, the packet losses in the path between source and destination occur due to packet collisions, fast movement and a limited communication range of vehicles. Reliability mechanisms at different layers ... -
