Vehicular cloud computing (VCC) is a promising paradigm for efficiently utilizing and sharing computing and storage resources on vehicles. However, the network topology and the available computing resources change rapidly due to vehicular mobility. In this paper, we study the task offloading problem in the vehicular cloud (VC), in which computing missions that are exclusively divided into interdependent tasks can be offloaded from the edge cloud and executed on vehicles in the VC to minimize the overall response time. A mobility-aware model based on vehicles’ stay time is adopted by considering the instability of computing resources caused by the high vehicular mobility. We formulate an NP-hard optimization problem for task offloading that considers the heterogeneity of vehicular computing capabilities and the interdependency of computing tasks. For this, a Mobility-Aware Vehicular Cloud task Offloading …
