- Abstract:
-
To reduce the moving cost and task completion time of the distribution process in a spatiotemporal crowdsourcing task, in this paper, by combining spatiotemporal crowdsourcing and path planning, a tabu search algorithm based on adaptive threshold is proposed. This algorithm uses online learning for path planning and designs a reasonable estimated waiting time for each task by matching crowdsourcing tasks in the area, thus, completing tasks in the shortest time. Through experimental comparison, we concluded that the average task time of the algorithm proposed in this paper is 13% and 23.3% lower than that of the Adaptive RT and ASPT algorithms, respectively, and the moving cost of the proposed algorithm is 6.99% and 25.9% lower than that of the Adaptive RT and ASPT algorithms, respectively.
