Edge intelligence is one of the key paradigms relatedto the efficient implementation of future wireless networks. Inthis context, the surrounding telecommunication infrastructureis intended to support the functioning of the wireless system. Thus, it is necessary to offload some computational efforts tothe system edge, allowing the infrastructure to learn and makeprospective decisions. However, for the reliable realization of theedge intelligence concept, the wireless system architecture shouldbe designed properly to minimize both storage cost and inducedlatency. In this paper, we compare three architecture proposals(centralized, distributed, and hybrid) tailored to the autonomousdriving use case, being one of the key vertical scenarios incontemporary and future wireless networks. We evaluate theperformance of an autonomous platooning system, where theoperating frequency is selected dynamically with the support ofinfrastructure to minimize the overall interference level in thewhole band. Extensive computer simulations have been carriedout to analyze the impact of the induced delay in signal processingand storage efficiency.

Database Supported Successive Interference Cancellation Scheme for Intra-platoon Communications
Sybis, Michal,Sroka, Paweł,Kliks, Adrian 한국통신학회 2022 Journal of communications and networks Vol.24 No.6
High reliability of wireless communications is a rudi-mentary requirement for guaranteeing safe autonomous driving. This paper discusses the performance of communications betweencars within autonomous platoons, with the application of aproposed database-supported successive interference cancellation(SIC) algorithm. By assumption, it utilizes the knowledge onother existing interfering transmissions (such as pre-enteredinformation on digital television transmissions stored in the road-side database) to remove the interfering signal at the receiverside. It is shown that this approach improves the bit error rate,and in turn - the reliability of intra-platoon transmission. Theproposed solution is evaluated using link-level extensive computersimulations.
