• W4226329077 abstract "Mobile crowdsensing (MCS), as an alternative to traditional sensor networks, has attracted much research attention because of its flexibility and low deployment fee. Compared with the traditional sensor networks, MCS exploits existing network infrastructures (such as edge servers and user devices) to intelligently cooperate with smart device owners. In this way, MCS combines machine intelligence and human intelligence to perform various sensing tasks more efficiently with a significantly lower cost. A challenging problem in MCS is data uploading, where mobile phone users as workers need to upload collected data to an MCS platform. In Xu and Song (2022), we proposed a heuristic approach to make a data transmission plan between mobile phone users and edge servers, which can help an MCS system leverage network resources in edge servers to facilitate data uploading efficiently. In this article, we reinvestigate the data uploading problem in Xu and Song (2022), analyze the heuristic approach’s drawbacks, and propose a deep reinforcement learning (DRL)-based method to complement these drawbacks. Specifically, we show that the heuristic approach may not sufficiently address heterogeneous cases, although it can achieve high efficiency in the homogeneous scenarios. Furthermore, we find that the heuristic method is not a one-fit-for-all method and cannot adjust itself when facing new scenarios. Instead of making a new fixed heuristic to deal with these new scenarios, we design an adaptive method based on DRL and graph neural networks (GNNs) to learn heuristics, enabling the new method to handle all possible situations in theory. Specifically, we train a DRL agent with a group of data uploading instances and then generalize the agent to other instances. Extensive numerical results show that the DRL-based approach achieves a high approximation ratio and performs stably in all sorts of experiment settings." @default.
