Selective Sensing Framework for Opportunistic Mobile Phone Sensing Networks.

Abstract
The rise of opportunistic mobile phone sensing paradigm is due to ubiquitous mobile phones usage. Optimisation of battery energy consumption and achieving required spatial coverage of sensing area are important issues under opportunistic mobile phone sensing networks. Human mobility enable collection of mobile phones sensor data and sensing area coverage by forming communication network with surrounding neighbors devices (mobile phones). This paper proposes a human mobility based selective sensing framework called as HWSS (Human Walk based Selective Sensing) for sensor data collection in opportunistic mobile phone sensing networks. In proposed HWSS method, mobile phones are selected for sensing task based on users current and predicted future locations and sensing overlap area. The proposed HWSS method is compared with non-selective sensing method (NSS), where all mobile nodes are allowed for sensing during sensor data collection process, in an given application area. The simulation results show that compared to NSS method proposed HWSS method achieves reduction in energy consumption and required spatial coverage.
