Journal ArticleDOI
Technical Communication: Angle-of-arrival localization based on antenna arrays for wireless sensor networks
TL;DR: A technique based on antenna arrays and angle-of-arrival (AoA) measurements is carefully discussed and trade-offs between the accuracy, localization time and the number of anchors in a network are addressed.
Journal ArticleDOI
Simulation scalability issues in wireless sensor networks
Esteban Egea-Lopez,Javier Vales-Alonso,Alejandro Santos Martinez-Sala,P. Pavon-Mario,Joan Garcia-Haro +4 more
TL;DR: This survey reviews problems of WSN performance evaluation both quantitatively and qualitatively while depicting a common suitable simulation model and briefly describes the most significant simulation frameworks available.
Journal ArticleDOI
An accurate radio channel model for wireless sensor networks simulation
Alejandro Santos Martinez-Sala,Jose-Maria Molina-Garcia-Pardo,Esteban Egea-Ldpez,Javier Vales-Alonso,Leandro Juan-Llacer,Joan Garcia-Haro +5 more
TL;DR: This paper proposes to use a low-computational cost, two slope, log-normal path-loss near ground outdoor channel model at 868 MHz in WSN simulations, validated by extensive real hardware measurements obtained in different scenarios and demonstrates that the two slope log- normal model provides more accurate WSN simulation at almost the same computational cost as the single slope one.
Journal ArticleDOI
Multiframe Maximum-Likelihood Tag Estimation for RFID Anticollision Protocols
Javier Vales-Alonso,V. Bueno-Delgado,Esteban Egea-Lopez,Francisco J. González-Castaño,Juan J. Alcaraz +4 more
TL;DR: The MFML-DFSA algorithm is compared with previous proposals and found to outperform these in terms of (lower) average identification time and computational cost, which makes it suitable for implementation in commercial RFID readers.
Journal ArticleDOI
Wireless communications deployment in industry: a review of issues, options and technologies
Esteban Egea-Lopez,Alejandro Santos Martinez-Sala,Javier Vales-Alonso,Joan Garcia-Haro,Josemaria Malgosa-Sanahuja +4 more
TL;DR: A thorough survey of all this requirements of wireless nets, reviews the existing wireless solutions, and explores possible matching between industry and the current existing wireless standards are presented.
