The proposed scheme employs a fuzzy logic-based edge node selection protocol to find the best edge nodes in a decentralized manner, which can achieve an efficient use of wireless resources by conducting packet forwarding through edges. A reinforcement learning algorithm is used to optimize the last two-hop communications in order to improve the adaptiveness of the communication routes. The proposed scheme selects different edge nodes for different types of communications with different context information such as connection-dependency (connection-dependent or connection-independent), communication type (unicast or broadcast), and packet payload size. We launch extensive simulations to evaluate the proposed scheme by comparing with existing broadcast protocols and unicast protocols for various network conditions and traffic patterns.<\/jats:p>","DOI":"10.3390\/s18072022","type":"journal-article","created":{"date-parts":[[2018,6,25]],"date-time":"2018-06-25T11:03:25Z","timestamp":1529924605000},"page":"2022","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["A Context-Aware Edge-Based VANET Communication Scheme for ITS"],"prefix":"10.3390","volume":"18","author":[{"given":"Chang","family":"An","sequence":"first","affiliation":[{"name":"Inner Mongolia Normal University, Hohhot 010010, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6853-5878","authenticated-orcid":false,"given":"Celimuge","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Computer and Network Engineering, The University of Electro-Communications, Tokyo 182-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tsutomu","family":"Yoshinaga","sequence":"additional","affiliation":[{"name":"Department of Computer and Network Engineering, The University of Electro-Communications, Tokyo 182-8585, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xianfu","family":"Chen","sequence":"additional","affiliation":[{"name":"VTT Technical Research Centre of Finland, FI-90571 Oulu, Finland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yusheng","family":"Ji","sequence":"additional","affiliation":[{"name":"Information Systems Architecture Research Division, National Institute of Informatics, Tokyo 101-8430, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,6,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"44","DOI":"10.1109\/TVT.2017.2760281","article-title":"Integrated Networking, Caching, and Computing for Connected Vehicles: A Deep Reinforcement Learning Approach","volume":"67","author":"He","year":"2018","journal-title":"IEEE Trans.
