MEC-enabled resource allocation in Internet of Vehicles

Abstract

Mobile edge computing (MEC), a promising technology, is widely used in the context of the Internet of Vehicles (IoV) owing to its robust computing capabilities and proximity to mobile devices. Leveraging its advantageous features, MEC facilitates lower latency and more efficient computing services for intelligent vehicles compared to preceding technologies. The tasks inherent to IoV exhibit varying sensitivities to latency, necessitating a nuanced approach to processing. Therefore, this study aims to develop a sophisticated solution in the form of a joint task sequencing and resource allocation (JTSARA) algorithm based on deep reinforcement learning. The primary objective is to adeptly manage both computing and communication resources within the MEC environment, thereby ensuring the fulfillment of performance requirements of tasks. Initially, tasks are categorized into distinct levels according to their latency tolerance. Subsequent to this classification, a method is formulated to optimize task sequencing, improving the efficiency of computational processing. Furthermore, we tackle the intricate challenge of resource allocation by transforming it into a Markov decision process, employing deep reinforcement learning for resolution. The feasibility and effectiveness of the proposed scheme are demonstrated through comprehensive simulation experiments, affirming its potential for enhancing the performance of IoV systems.
