面向异构效用的移动群智感知多目标任务分配
Multi-objective task assignment towards heterogeneous utilities in mobile crowdsensing
摘要
Abstract
Most of the existing MCS task allocation methods often only consider the unilateral utility of workers or platforms,and the composition of utility is not comprehensive enough.Therefore,this paper designed a heterogeneous utility mechanism for both workers and platforms based on the worker reputation index and task proficiency index.It proposed a dual-population competitive multi-objective evolutionary algorithm(DCMEA)to obtain the optimal worker and platform heterogeneous utilities.The algorithm firstly initialized the population using a stochastic greedy algorithm,then divided the population into a winner population and a loser population using a binary bidding tournament algorithm,and employed different evolutionary strategies for each population.Finally,this paper proposed the repair operator to make the invalid individuals in the evolution process satisfy the constraint.Experiments on real-world datasets show that DCMEA converges faster than the baseline algorithm,and can find more accurate and stable task allocation solution sets,while maintaining its performance in more complex scenarios.关键词
