Towards Personal Virtual Traffic Lights

Traffic control management at intersections, a challenging and complex field of study, aims to strike a balance between safety and efficient traffic control. Nowadays, traffic control at intersections is typically done by traffic light systems which are not optimal and exhibit several drawbacks, such as poor efficiency and real-time adaptability. With the advent of Intelligent Transportation Systems (ITS), vehi...

Implementation and analysis of Wireless Flexible Time-Triggered protocol

During the last few years, wireless low-power communications experienced an increasing coexistence and traction as a result of the higher demand posed by power constrained applications. On the other hand, this increasing wireless coexistence is a growing concern and Low-power wireless communication protocols have been shown to experience a significant timeliness and reliability degradation under certain interfe...

Implementing the Wireless FTT Protocol: A Feasibility Analysis

Low-power wireless communication protocols have been shown to experience a significant timeliness and reliability degradation under certain interference profiles. Provided that this impairment has hindered their wide adoption in demanding real-time scenarios, the Wireless Flexible Time Triggered (WFTT) protocol has been recently proposed targeting applications with stringent timeliness requirements. This protoc...

An assessment of the IEEE 802.15.4 PHY immunity to WiFi interference

An increasing number of IEEE 802.15.4-based protocols has emerged over the last few years targeting industrial automation applications. One motivation for this is the IEEE 802.15.4 support of low-power communications, which enables deployments with stringent autonomy requirements (e.g., Wireless Sensor Networks). However, this feature may well be responsible for a degraded performance in scenarios where the med...
