报告摘要：
Participatory sensing is a powerful paradigm in which users participate in the sensing campaign by collecting and crowdsourcing fine-grained information and opinions about events of interest (such as weather monitoring, traffic conditions or accidents, environmental noise and pollution, crime scenes, emergency response, healthcare and wellness management), thus leading to actionable inferences and decisions. However, human interactions with cyber-physical-social systems pose significant challenges in terms of energy efficiency of mobile devices, sensing coverage and localization, user incentives for participation, information quality and reliability, big data and scaling issues, spatio-temporal uncertainty, location and data privacy, trust and security, and so on. For example, due to limited resources of mobile devices, the sensed data are usually offloaded to the cloud and therefore energy-efficient architectures and algorithms, resource and service discovery mechanisms are needed for participatory sensing in the mobile cloud. Other important challenges include mobility and user incentives to provide reliable information. This talk will discuss unique challenges and opportunities in the emerging field of participatory urban sensing with applications to smart cities. Novel solutions will be presented to address some of these challenges along with experimental results, followed by directions for future research.
