Dynamic QoS-aware event sampling for community-based participatory sensing systems
Ioannis Boutsis, Vana Kalogeraki · 2012
Over the recent years, the proliferation of mobile networking and the increasing capabilities of smartphone devices have led to the development of the "Community-based Participatory Sensing" approach, where users participate in data collection and sharing in a wide range of application areas such as entertainment, transportation and environmental monitoring. This paper develops a participatory sensing system that uses a sampling mechanism that aims to stimulate user participation in dynamic groups that provide services and get compensated for the services they provide. Users participate in the community by sensing and sharing streams of events. The system then uses a sampling mechanism to define a subset of events that preserves the characteristics of the stream data and provides the highest "information gain" to the system, given the budget and resource constraints. Our experimental results illustrate that our approach is practical, efficient and depicts good performance.
