说明：  在移动群智感知的空间任务分配问题中用户与任务的空间距离直接影响完成任务所需的成本，而现有的研 究在这方面却考虑不足，因此以最小化感知成本为目标设计了移动群智感知中的空间任务分配机制。
(In the space task allocation problem of mobile group intelligence perception, the space distance between users and tasks directly affects the cost of completing tasks. However, it is not enough to consider this aspect, so the spatial task allocation mechanism in mobile group intelligence perception is designed with the goal of minimizing perception cost.)
