In this work we address the challenges arising when developing, testing and deploying software for Wireless Sensor Networks. We investigate both pre-deployment software design, as well as efficient post-deployment updates. We present a combined pre-deployment framework that simulates the network...
Medium access in applications of wireless sensor networks is often uncoordinated while sensor nodes communicate bursty flows of data. Therefore random-access packet-based communication schemes are suitable for such networks. Preamble detection is an important task in packet-based communication...
Monitoring of environmental conditions in and around oil sands developments has been underway for years. However, recent reviews have indicated the need for a more comprehensive, scientifically-rigourous and transparent monitoring program and have provided recommendations for design and...
Base station (BS) positioning is considered an effective method to improve the performance of a Wireless Sensor Network (WSN). The goal of this dissertation is to minimize total energy consumption and to prolong lifetime of a WSN. First, the idea of the BS positioning in WSNs through our...
Deployment Planning for Location Recognition in the Smart-Condo™: Simulation, Empirical Studies and Sensor Placement OptimizationDownload
The Smart-Condo™ is a comprehensive platform that aims to provide a variety of services, based on information gleaned from sensors deployed in an apartment, that can potentially improve healthcare delivery. One of our main objectives has been to develop an accurate non-invasive...
In this project we study the problem of wireless sensor network (WSN) node placement in a modelled environment. Although various optimal and sub-optimal techniques with different objectives and constraints such as maximizing coverage, network lifetime and reliable data transfer have previously...
The Wireless Sensor Networks (WSNs) have emerged as a new paradigm for collecting and processing data from physical environments, such as wild life sanctuaries, large warehouses, and battlefields. Users can access sensor data by issuing queries over the network, e.g., to find what are the 10...
Technical report TR10-03. Top-k queries are a popular type of query in Wireless Sensor Networks. Typical solutions rely on coordinated root-to-nodes and nodes-to-root messages and on maintaining filters at the nodes, aiming at suppressing unnecessary messages, hence saving energy and furthering...
Monitoring Seasonal and Secondary Succession Processes in Deciduous Forests using Near-Surface Optical Remote Sensing and Wireless Sensor NetworksDownload
The goal of this thesis is to address the need for improved monitoring of forest ecosystem dynamics in the context of anthropogenic global change by proposing the use of near-surface optical remote sensing approaches paired with emerging wireless sensor network (WSN) technologies in order to...
The use of Wireless Sensor Networks (WSNs) in various surveillance and monitoring tasks have attracted a wide and growing attention in recent years. The thesis considers a class of intrusion detection problems where an unauthorized person or object aims to traverse part of the geographical area...
