Collaborative opportunistic sensing with mobile phones

Abstract: Mobile phones include a variety of sensors that can be used to develop context-aware applications and gather data about the user's behavior, including the places he visits, his level of activity and how frequently and with whom he socializes. The collection and analysis of these data has been the focus of recent attention in ubiquitous computing, giving rise to the field known as mobile sensing. In this work, we present a collaborative extension to InCense, a toolkit to facilitate behavioral data gathering fro… Show more

“…However, these studies do not focus on underserved regions. While other mobile sensing platforms (like FunToolkit [20], InCense [21]) are successful in collecting data, they are inadequate for our context where individuals do not have the resources to pay for a monthly data usage plan, and the neighborhood has limited Wi-Fi access and poses several security challenges.…”

“…Local Collaborative Sensing: There are also works on local collaborative sensing; however, these works do not consider the sequential nature of past information into the collaboration process [12]. For example, Mantyjarvi et al [13] present a collaborative sensing approach where a device, upon noticing a change in its local context beyond a threshold value, requests contexts from its surrounding devices so as to increase the accuracy of its context vector.…”

“…Finally, the "optimum node" module elects the clique leader (the most informative smartphone) to record the audio data and notifies the condition of deactivation to the other smartphones from capturing the duplicate audio signal. It also helps in sorting the smartphone list based on their audio signal strength which is Mobile Information Systems eventually utilized by the locomotive "signature collection" module to opportunistically check on and trigger the accelerometer sensor on the smartphones [41]. e server-side architecture consists of two main logical subcomponents: (i) occupancy context model and (ii) location context model.…”
