In this article, we put forward a caching-enabled task offloading strategy, by caching and reusing the universal context data at the edge server, to avoid duplicated data transmission in VEC systems. The goal is to minimize the overall response latency for all the tasks, by jointly optimizing task offloading, content caching, and resource allocation decisions in VEC. The optimization problem is formulated as a Mixed-Integer Nonlinear Programming (MINLP) problem. To efficiently solve this problem, we decompose this problem into two subproblems, namely, the computing Resource Allocation (RA) problem and the Joint Offloading and Caching (JOC) problem. The corresponding algorithms are put forward to solve the content caching and task offloading problems, respectively. Numeric evaluation reveals that our strategies and algorithms can achieve better performance in minimizing the overall response latency, in comparison with other approaches.<\/jats:p>","DOI":"10.1145\/3732782","type":"journal-article","created":{"date-parts":[[2025,4,28]],"date-time":"2025-04-28T10:59:08Z","timestamp":1745837948000},"page":"1-24","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Joint Optimization of Task Offloading Content Caching and Resource Allocation in Vehicular Edge Computing"],"prefix":"10.1145","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4471-9856","authenticated-orcid":false,"given":"Chaogang","family":"Tang","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, China University of Mining and Technology, Xuzhou, China, and Mine Digitization Engineering Research Center of the Ministry of Education, Xuzhou, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4761-9973","authenticated-orcid":false,"given":"Huaming","family":"Wu","sequence":"additional","affiliation":[{"name":"Center for Applied Mathematics, Tianjin University, Tianjin, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9905-8952","authenticated-orcid":false,"given":"Ruidong","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Science and Engineering, Kanazawa University, Kanazawa, Japan"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8657-3800","authenticated-orcid":false,"given":"Joel J.
