With the rise of internet of things an immense number of RFID tags will be associated with different systems that require not only strong authentication protocols, but also time- and power- efficient protocols to authenticate more tags in a given time window. In current tag authentication protocols, a tag is considered authentic if the interrogators find a(More)
This paper discusses the application use of our WSN platform called Sprouts to monitor the current erosion conditions and retrieval of lost shovel-teeth in the Oil Sands mining operations of Ft. McMurray, Alberta, Canada. The modular architecture design of Sprouts allows us to customize the platform to monitor the thickness of shovel teeth and localize(More)
In RFID based inventory systems, counting and estimating the number of the surrounding tags without reading each tag individually is a challenge. In this paper we propose an estimation function that considers the variance of collision and empty slots during the estimation frame. In addition, two schemes, Variance and Modulation Silencing based Estimation(More)
— In harsh operational conditions, machines lose components on a frequent basis, causing a significant footprint to the surrounding environment. This affects operational up-time, safety measures and cost effectiveness. This paper proposes the use of an integrated RFID-WSN architecture to reduce the footprint of mining equipment used in the Canadian Oil(More)
RFID technology as an enabler of the Internet of Things (IoT) is extensively utilized for object localization. Existing RFID-based object localization techniques follow a centralized and coordinated approach. Indeed, none is designed to leverage RFID crowdsourcing for the purpose of object localization. In this paper, we propose a cooperative scheme to(More)
In RFID tag identification, tag-to-tag collisions pose a challenging problem to protocol designers. Currently the modulation silencing mechanism (MSM) has been proposed to overcome the time and power wasted on collision slots during tag identification. In MSM, the time of collision slots is reduced by the assistance of the continuous wave absence detection(More)
This paper discusses the application of our Wireless Sensor Network platform called Sprouts, to monitor the steel shovel-teeth on shovelling equipment used in oil sands mining operations in Ft. McMurray, Alberta, Canada. If a fallen shovel-tooth reaches the rock crushers, serious damage to the crusher gears is expected. The Sprouts platform is utilized to(More)
