Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Title: Efficient wireless power transfer for Internet of Things devices

Abstract: The Internet of Things (IoT) is an emerging computing paradigm that consists of devices coupled with internet connectivity without human interaction. It is projected that in the near future, common industrial, personal, office and household devices, machines and objects will hold the ability to sense, communicate and process information ubiquitously. The ever-growing increase in modern and ubiquitous applications of IoT are causing energy scarcity, which is a serious threat to the lifetime of the network. Wireless power transfer emerges as a promising solution to replenish the IoT devices. In wireless power transfer, energy is transferred to sensor nodes through dedicated energy transmitters. In this talk, we will first give a brief overview of IoT and requirements and challenges of wireless power transfer. We then present a mechanism to place energy transmitters and determine a minimum number of energy transmitters. This talk offers an energy-efficient scheduling scheme for energy transmitters. The focus is to minimize the energy consumption of energy transmitters while keeping sensor nodes sufficiently charged. Finally, we provide simulation results which illustrate the performance of efficient wireless power transfer for IoT devices.
