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...
In this paper, we propose two schemes for sensor and relay node placement in environmental sensing applications. The first scheme aims at maximizing the network lifetime by reducing the total energy consumption. The second does so while maintaining fault-tolerance constraints. It guarantees a lower bound on the minimum required number of faulty nodes. Both schemes are based on a 3-D hierarchical architecture,...
Grid-based deployments of Wireless Sensor Networks (WSNs) are widely used in a multiplicity of applications. However, practical factors such as communication irregularity and placement uncertainty have to be considered for more efficient deployments. In this paper, we examine connectivity properties of the 3D grid-based deployment when sensor placements are subject to random errors around their corresponding...
Device deployment plays a key role in the performance of any Wireless Sensor Network (WSN) application. WSN device deployment (i.e. the numbers and positions of the devices) must consider several design factors, like coverage, connectivity, lifetime, etc. However, connectivity remains the most fundamental factor especially in harsh environments. Extensive work has been applied on connectivity in WSN...
