Proximity-Aware Worker Preferred Task Allocation for Spatial Crowdsourcing

Nellissery Cheryl Anto Jaya, G P Sajeev
2020 Procedia Computer Science  
Spatial crowdsourcing is a paradigm of crowdsourcing, that extends beyond the traditional web-based crowdsourcing by including physical entities of the geographic system.  ...  The task allocation on a spatial crowdsourcing platform based on proximity between task and worker is challenging since the worker must be physically present at the location to complete the task.  ...  Considering location data is exact it is still not enough to assign tasks correctly. The way in which the distance is calculated plays a role in the correct task assignment.  ...
