中文摘要： 参与式感知技术及其众包应用在公众健康、环境保护、社会生活等诸多领域都有着广阔的发展前景。本项目对参与式感知系统中基于众包的动态群组构造算法开展研究，首先根据参与式感知应用的特点提出三种众包模型，并且针对不同众包模型研究动态群组构造方法；研究参与式感知系统的移动性、社会特征和机会特征对群组构造的影响，以及在机会连接的背景下构造群组的方法；设计有效的用户声望评估模型，基于用户声望值进行可信群组构造；结合感知数据（或任务）类型、用户声望、用户档案上下文等要素设计用户激励策略，运用动态定价博弈方法进行群组构造。最后将构建一个由100个智能手机和100个传感器节点组成的参与式感知实验系统，并在实验系统上对设计的相关算法进行有效性验证和性能评价。

英文摘要： Participatory sensing technology and crowdsourcing applications have great potentials in areas of healthcare, enviroment protection, social life, etc.This project addresses crowdsourcing-based dynamic community creation approaches in participatory sensing systems.Three crowdsourcing models for participatory sensing were first proposed according to specific types of crowdsourcing applications. Community creation approaches will be developed based on each crowdsourcing model.The impacts of node mobiliy,social and opportunistic features on community creation are focused, and community creation schemes under opportunistic enviroment will be proposed as well. An efficient user reputation evaluation model is to be designed, which is further exploited in trustful community creation.User incentive polocies will be investigated based on data (or task) types, user reputation,and user profiles, and dynamic pricing gaming will be considered in community creation.Finally,we will build a participatory sensing experiment system with 100 smart phones and 100 sensor nodes for algorithm validation and performance evaluation.
