摘要

在移动众测（MCS）系统中，由于请求者的异质性，他们处于移动状态，这意味着请求者会在不同时间加入或离开移动众测系统，他们的数据需求也是时变的。请求者的流动性导致的请求者的不确定性会造成请求者和参与者之间匹配的不稳定性，即由于竞争激烈程度的变化导致请求者和参与者的不满，既定的匹配算法无法完成。针对请求者的流动性，我们设计了一种基于联盟的动态激励机制，请求者可以分别离开、加入 MCS 系统，并改变自己的数据需求。针对不稳定性，我们将动态机制分为不同阶段，并在每个阶段更新匹配规则。我们提出了一种基于动态斯塔克尔伯格博弈的独特算法和相应的更新算法，以分析请求者和参与者的匹配策略，从而实现最优匹配。通过证明更新规则的稳定性，我们保证了请求者流动时匹配的稳定性。通过数值分析，联盟的形成可以大大降低弱请求者的成本，最多可降低 90%。此外，在我们的机制中，任何请求者最多参与两次博弈，选择率可达 100%。

Requester mobility for mobile crowdsensing system: A dynamic alliance-based incentive mechanism

In the Mobile Crowdsensing (MCS) system, due to the heterogeneity of requesters, they are in mobile which means requesters will join or leave the MCS system at different times and their data demands are time-varying. The uncertainty of requesters caused by requester mobility will generate the instability of the match between requesters and participants which means the established matching algorithm cannot be completed due to the dissatisfaction of requesters and participants caused by the changes in the intensity of competition. For requester mobility, we design a dynamic alliance-based incentive mechanism where requesters can leave, join the MCS system separately, and change their data needs. To the instability, we divide the dynamic mechanism into different stages and will update the matching rules in each stage. A unique algorithm based on the dynamic Stackelberg game and the corresponding updated algorithm is proposed to analyze the matching strategies of requesters and participants to make an optimal match. By proving the stability of the updated rules, we guarantee the stability of the match with requester mobility. Through numerical analysis, alliance formation can significantly reduce weak requesters’ costs by at most 90%. Besides, in our mechanism any requester participates in the game at most twice, the chosen rate can be up to 100%.
