Public Sensing – Using Your Mobile Phone for Crowd Sourcing
نویسنده
چکیده
Public sensing is a new concept for gathering sensor data by utilizing ubiquitously available mobile devices such as smartphones. By leveraging the crowd of mobile devices, we can build a mobile sensor network with excellent coverage in urban areas without large up-front investments for building a dedicated sensor network. In this paper, we present several concepts and methods to improve the usability and efficiency of public sensing systems. In detail, we present a virtual sensor abstraction allowing applications to query for sensor values without having to know the population of mobile devices. Moreover, we show how model-driven sensing can improve both the quality of sensing as well as the energy-efficiency of mobile devices participating in public sensing. Finally, we present a method for optimizing the communication of sensor values gathered by mobile devices by exploiting the characteristics of mobile communication technologies.

Crowd-sourced BioGames: managing the big data problem for next-generation lab-on-a-chip platforms.
We describe a crowd-sourcing based solution for handling large quantities of data that are created by e.g., emerging digital imaging and sensing devices, including next generation lab-on-a-chip platforms. We show that in cases where the diagnosis is a binary decision (e.g., positive vs. negative, or infected vs. uninfected), it is possible to make accurate diagnosis by crowd-sourcing the raw da...

In this paper we describe SmartRoad, a road sensing system that generates and collects mobile sensory data from vehicle-resident mobile phones, in enabling and supporting crowd-sourced road sensing applications and services, as an alternative to expensive road surveys conducted traditionally. We implement the SmartRoad prototype system, and deploy it on 35 volunteer users’ vehicles for 2 months...

Securing safety in private and public spaces such as for public transport involves considerable costs. However, the effectiveness and benefits for safety are often disputed. The causality between the implementation of security measures and the occurrence of security-relevant events and perceived safety is not always obvious. A major contribution to improving this situation is to develop tools f...
متن کاملCrowdsensing in Opportunistic Mobile Social Networks: A Context-aware and Human-centric Approach
In recent years, there have been efforts to collect human contact traces during social events (e.g., conferences) using Bluetooth devices (e.g., mobile phones, iMotes). The results of these studies have enabled the ability to do the crowd-sourcing task from within the crowd, in order to answer questions, such as: what is the current density of the crowd, or how many people are attending the eve...
متن کاملCrowd Sourcing Indoor Maps with Mobile Sensors
The paper describes algorithms required to enable the crowd sourcing of indoor building maps, i.e., where GPS is not available. Nevertheless to enable crowd sourcing we use the 3-axis accelerometers and the 3-axis magnetometers available in many smart phones and the piezometer in a Nike running shoe. Volunteers carry the sensors while walking around in buildings, and use some application on the...
