提供长期的参与激励,以增强感知能力

Providing Long-Term Participation Incentive in Participatory Sensing

Lin Gao, Fen Hou, Jianwei Huang

摘要:

提供足够的长期参与激励对于参与式传感系统保持足够数量的活跃用户(传感器),以便收集足够数量的数据样本并支持期望的服务质量水平是重要的。在这项工作中,我们考虑了传感器选择问题,在一般的时间依赖和位置感知的参与式传感系统,考虑到长期的用户参与激励明确考虑。我们系统地研究了不同的信息场景下的问题,关于未来的信息和当前的信息(实现)。特别是,我们提出了一个基于Lyapunov的VCG拍卖政策的在线传感器选择,它渐近收敛到最佳的离线基准性能,即使没有未来的信息和(当前)信息不对称。大量的数值结果表明,我们提出的政策优于文献中的最先进的政策,在用户参与(例如,将用户丢弃概率降低25%到90%)和社会性能(例如,增加社会福利15%至80%)。

英文摘要:

Providing an adequate long-term participation incentive is important for a participatory sensing system to maintain enough number of active users (sensors), so as to collect a sufficient number of data samples and support a desired level of service quality. In this work, we consider the sensor selection problem in a general time-dependent and location-aware participatory sensing system, taking the long-term user participation incentive into explicit consideration. We study the problem systematically under different information scenarios, regarding both future information and current information (realization). In particular, we propose a Lyapunov-based VCG auction policy for the on-line sensor selection, which converges asymptotically to the optimal off-line benchmark performance, even with no future information and under (current) information asymmetry. Extensive numerical results show that our proposed policy outperforms the state-of-art policies in the literature, in terms of both user participation (e.g., reducing the user dropping probability by 25% to 90%) and social performance (e.g., increasing the social welfare by 15% to 80%).
