It allows mobile devices to offload their computation\u2010demanding and latency\u2010critical tasks to the resource\u2010rich MEC servers. Accordingly, MEC can significantly improve the latency performance and reduce energy consumption for mobile devices. Nonetheless, privacy leakage may occur during the task offloading process. Most existing works ignored these issues or just investigated the system\u2010level solution for MEC. Privacy\u2010aware and user\u2010level task offloading optimization problems receive much less attention. In order to tackle these challenge<jats:bold>s<\/jats:bold>, a privacy\u2010preserving and device\u2010managed task offloading scheme is proposed in this paper for MEC. This scheme can achieve near\u2010optimal latency and energy performance while protecting the location privacy and usage pattern privacy of users. Firstly, we formulate the joint optimization problem of task offloading and privacy preservation as a semiparametric contextual multi\u2010armed bandit (MAB) problem, which has a relaxed reward model. Then, we propose a privacy\u2010aware online task offloading (PAOTO) algorithm based on the transformed Thompson sampling (TS) architecture, through which we can (1) receive the best possible delay and energy consumption performance, (2) achieve the goal of preserving privacy, and (3) obtain an online device\u2010managed task offloading policy without requiring any system\u2010level information. Simulation results demonstrate that the proposed scheme outperforms the existing methods in terms of minimizing the system cost and preserving the privacy of users.<\/jats:p>","DOI":"10.1155\/2021\/6622947","type":"journal-article","created":{"date-parts":[[2021,6,11]],"date-time":"2021-06-11T20:35:09Z","timestamp":1623443709000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Privacy\u2010Aware Online Task Offloading for Mobile\u2010Edge Computing"],"prefix":"10.1155","volume":"2021","author":[{"given":"Dali","family":"Zhu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0551-6535","authenticated-orcid":false,"given":"Ting","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8410-8403","authenticated-orcid":false,"given":"Haitao","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiyan","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liru","family":"Geng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5984-1299","authenticated-orcid":false,"given":"Yinlong","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,6,11]]},"reference":[{"key":"e_1_2_11_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2019.2891113"},{"key":"e_1_2_11_2_2","doi-asserted-by":"crossref","unstructured":"GuR.
