StareCrowd: A New Paradign for Mobile Crowdsensing

With the proliferation of mobile devices with rich sensor peripherals and computation capability, mobile crowdsensing, where communities contribute sensing information and human intelligence using mobiledevices, has shown promises in enabling a variety of environmental, commercial and social applications. Existing solutions to mobile crowdsensing, however, suffer from the well-known cold start problem, where the shortage of eligible contributors makes it difficult to extract any meaningful information and make decisions accordingly. In addition, mobile crowdsensing poses great challenges in handling noisy and faulty data from resource-constrained mobile devices, minimizing user intervention, and real-time data acquisition, processing, and analytics. The goal of this project is to develop a novel crowd sensing paradigm, ShareCrowd, that facilitates sharing and aggregation of sensing and user-contributed data programmatically. ShareCrowd is a two-sided platform and allows two distinct user groups, namely, data requesters and data contributors across multiple apps to provide each other with net benefits. To extract useful information from crowdsensed data and to detect data falsification, novel data analytical techniques will be developed. To address resource limitation, mobile crowdsensing costs will be explicitly considered in the incentive mechanism design of ShareCrowd in the form of a payment system. The need for user intervention will be mitigated by active learning-based data query techniques, which obtain more data and annotations only when necessary. Mobile crowdsensing extends the traditional IoT that interconnects physical items embedded with sensors to consumer-centric mobile devices that are already "deployed in the field". The project tackles the key roadblocks to unleashing the power of mobile crowdsensing, and thus can improve the efficiency of existing services and businesses of our industrial partners and other organizations, and generate new forms of revenue by contributing to the Apps economy value chain in Canada.
