Aggregation in Smartphone Sensor Networks

2014 IEEE International Conference on Distributed Computing in Sensor Systems, 2014
The first wave of sensor network deployments from the early 2000s relied on aggregation-a strategy in which readings are combined locally using low-power radio links before they are communicated to the gateway. Aggregation reduced dependence on battery-draining, long-distance radio links, and reduced redundancy among reported data.

Battery Consumption of Smartphone Sensors

2015 11th International Conference on Signal-Image Technology & Internet-Based Systems (SITIS), 2015
The rapid development of smartphones entails the effect that not only the development of hardware is needed but of the batteries responsible for supplying sensors. The increased resource requirements drain mobile devices' batteries faster and faster. People usually can be seen searching for opportunities of recharging their mobile devices at airports ...

Smart physics with smartphone sensors

2014 IEEE Frontiers in Education Conference (FIE) Proceedings, 2014
Smartphone' acceleration sensors have got useful applications in standard physical situations. We have taken advantage of its capabilities in a number of Physics experiments and perform them in a series of examples within classical mechanical and kinematic situations such as free and damped oscillations due to Earth's gravity.

Smartphone Irrigation Sensor

IEEE Sensors Journal, 2015
An automated irrigation sensor was designed and implemented to use in agricultural crops. The sensor uses a smartphone to capture and process digital images of the soil nearby the root zone of the crop, and estimates optically the water contents. The sensor is confined in a chamber under controlled illumination and buried at the root level of the ...

Sensitivity of Sensors Built in Smartphones

2015
In our earlier researches we examined the reliability and accuracy of sensors used in outdoor positioning. Results have shown that they are not as reliable as many think. So the question rightly arises: what sensor could be the solution for indoor navigation.

Activity recognition using smartphone sensors

2013 IEEE 10th Consumer Communications and Networking Conference (CCNC), 2013
Motion sensor embedded smartphones have provided a new platform for activity inference. These sensors, initially used for cell phone feature enhancement, are now being used for a variety of applications. Providing cell phone users information about their own physical activity in an understandable format can enable users to make more informed and ...

Human-Activity Recognition with Smartphone Sensors

2020
The aim of the Human-Activity Recognition (HAR) is to identify the actions carried out by an individual given a data set of parameters recorded by sensors. Successful HAR research has focused on the recognition of relatively simple activities, as sitting or walking and its applications are mainly useful in the fields of healthcare, tele-immersion or ...
