Integrating Licensed and Unlicensed Spectrum in the Internet of Vehicles with Mobile Edge Computing

Abstract

In order to satisfy the application requirements in Internet of Vehicles scenarios, it is important to efficiently utilize different wireless spectrums while considering the dynamic features of network environments. In this article, we propose a context-aware communication approach to efficiently integrate different licensed and unlicensed spectrums leveraging the edge computing technologies. In addition, a joint aggregation, caching, and decentralization scheme is proposed to efficiently combine route aggregation, data caching, and decentralized computing approaches to compensate for the limited wireless resources. Asynchronous multihop broadcast and asynchronous multihop unicast schemes are introduced to improve the routing performance in multihop broadcast and multihop unicast communications, respectively. We conduct computer simulations to evaluate the effects of the proposed scheme by comparing it with other baseline approaches.
