Occupancy estimators (sensors which can accurately estimate the number of people occupying a space) hold great potential for reducing the power usage of lighting and heating, ventilation, and air conditioning (HVAC) systems. In this paper we use low-resolution thermal sensors for occupancy estimation, due to their high temporal and spatial resolution and low invasiveness. We extend the connected component...
This paper investigates a time sharing (TS) based user pairing strategy to accommodate similar gain users in non-orthogonal multiple access (NOMA) systems, termed as TS- NOMA. A scenario is considered in which the distribution of users in a cellular area is non-uniform, such that the number of cell center users is less than cell edge users. In this case, if two user conventional NOMA (C-NOMA) pairing...
The Internet of Things(IoT) has been developing rapidly since the past decade. It is becoming a crucial part of everyday life. It is becoming a way of living in which machines perform activities on their own by communicating with each other, without the need for human beings to instruct them. In such a scenario, which concerns daily life, privacy, and secrecy should be of at most priority. Since in...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Energy Harvesting is a solution for continued operation of WSNs without depending on batteries. This paper introduces REAPer, an adaptive energy harvester for microsources that can be configured and monitored by the supplied WSN node. We combine REAPer with an IdealVolting capable sensor node that can fully exploit the monitoring and control capabilities of REAPer. The efficiency and overhead of the...

Cities are increasingly providing public access to a variety of transportation-related "big data", such as the real-time location of taxis, crowdedness level of buses and arrival times of trains. In this talk, Archan will introduce the concept of socio-physical analytics, which fuses such transportation-related data across multiple modalities (such as buses, taxis and parking garages) with...
The internet of things refers to collection of internet connected computational devices embedded into the objects of the physical world. It is expected that some of these devices perform sensing and actuation functionality. Visions of the internet of things often refer to a world were many (or all) the physical objects we interact with are part of the internet of things. In recent years the IoT paradigm...
Recent years have seen both mobile devices become more prominent and rapid growth in video traffic across mobile networks. This trend is expected to continue with the main constraint on mobile devices being their battery life. With the growth in performance potential, users want more out of their devices which leads to issues including battery powered mobile devices not being capable of surviving...
Coordination under precision demands is an important aspect of human motor performance ability. It is usually evaluated through a carefully selected set of physical exercises, which follow the same scheme: An examiner presents candidates with a task to perform, monitors their correct task execution, and manually tracks the score achieved by each candidate. However, the latter two steps impose a significant...
Networked embedded software systems incorporate varying degrees of adaptation behavior to sustain their operations with acceptable quality of service (QoS), in the face of hostile external events — such as resource outages in a cloud service, road slipperiness in a car driving, etc. For instance, a highly agile cruise control system of a car may dynamically adjust its controller parameters...
An algorithm, Travelling Salesperson Problem for Data Collection (TSP-DC), is presented which can plan tours for collected data from sensor nodes using a mobile sink. This is the first work which can deal with multiple different data ranges and data loads for each sensor node. Linear programming is used to schedule data transmissions to different nodes to reduce the overall tour time. Simulation results...
Wireless Sensor Networks (WSNs) are playing remarkable contribution in real time decision making by actuating the surroundings of environment. As a consequence, the contemporary agriculture is now using WSNs technology for better crop production, such as irrigation scheduling based on moisture level data sensed by the sensors. Since WSNs are deployed in constraints environment, the life time of sensors...
As a step toward sustainable wireless sensing, we present a proof of concept system that uses a Plant Microbial Fuel Cells (PMFC) as a power source. To match the very low power production capabilities of the PMFC, we couple it with an ultra-low power wake-up receiver used as a trigger for sampling and transmission of the sensed value. We demonstrate that this combination, with a new, receiver initiated...
