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 monitor the viability of the shovel-teeth...
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 localize mobile RFID tags using heterogeneous,...
Wireless Sensor Networks (WSNs) offer distinctive sensing solutions in numerous application domains which comprise harsh operating environments. Sensing in such environments expose sensing nodes to several performance degradation factors which obstruct sensing and/or data reporting. Sprouts WSN platform, developed by TRL, overcomes the challenging factors of harsh environments. In this paper we introduce...
Reliable and energy-efficient reading of Radio Frequency IDentification (RFID) tags is of utmost importance, especially in mobile and dense tag settings. We identify tag collisions as a main source of inefficiency in terms of wasting both medium access control (MAC) frame slots and reader's energy. We propose modulation silencing (MS), a reader-tag interaction framework to limit the effect of tag...
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 their position upon detachment. Utilizing our...
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 Sands industry. Sensors and RFID tags provide both...
Stage optimization of the hardware implementation of the popular encryption algorithms, the Advanced Encryption Standard (AES), is presented. The optimization, for lower power dissipation, is based on implementing the Multi Threshold CMOS (MTCMOS) technique in each of the AES stages. The critical paths are implemented using high performance gates based on high driving current transistors. For the...
