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

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

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

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

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.
