Abstract

The latest manifestation of “all connected world" is the Internet of Things (IoT), and Internet of Vehicles (IoV) is one of the key examples of IoT these days. In Social IoV (SIoV), each vehicle is treated as a social object where it establishes and manages its own Social Network (SN). Incidentally, most of the SIoV research in the literature is related to proximity-based connectivity and interactions. In this paper, we bring people in the loop by incorporating their SNs. While emphasizing a recommendation scenario, in which vehicles may require recommendations from SNs of their owners (in addition to their own SIoV), we proposed an agent-based model of information sharing (for context-based recommendations) on a hypothetical population of smart vehicles. Some important hypotheses were tested using a realistic simulation setting. The simulation results reveal that a recommendation using weak ties is more valuable than a recommendation using strong ties in pure SIoV. The simulation results also demonstrate that recommendations using the most-connected person in the social network are not more valuable than recommendation using a random person in the social network. The model presented in this paper can be used to design a multi-scale recommendation system, which uses SIoV and a typical SN in combination.

Highlights

Inter-connectivity of all objects of the universe and, the full digitization of the fabric of life has been a scientific quest for quite long [1]
We investigate the competence of Social IoV (SIoV)—with and without a social network—towards provisioning of accurate recommendations to the users in a dynamically changing environment
Work This paper proposed an agent-based model for a recommendation system powered by the expected capabilities of the futuristic SIoV

Summary

Introduction

Inter-connectivity of all objects of the universe and, the full digitization of the fabric of life has been a scientific quest for quite long [1]. Many components of this vision are already in place, like the blocks of a puzzle. One of the most significant recent developments towards this, no doubt, is the Internet of Things (IoT) [2,3]. The last decade has seen exciting developments which are related to IoT. Following the “Internet of-” idiom, the Internet of Vehicles (IoV) [4]) is already visible and ready to transform the way we live in modern cities.
