Abstract
Driven by both safety concerns and commercial interests, popular content distribution (PCD), as one of the key services offered by vehicular networks, has recently received considerable attention. In this paper, we address the PCD problem in highway scenarios, in which a popular file is distributed
Highlights
Vehicular ad hoc networks (VANETs) have been envisioned to provide increased convenience and efficiency to drivers, with numerous applications ranging from traffic safety, traffic efficiency to infotainment [1, 2]
We propose a distributed approach based on coalition formation games to address the popular content distribution (PCD) problem in CR-VANETs
We have proposed a p2p scheme using V2V communications to solve the PCD problem in VANETs
Summary
Vehicular ad hoc networks (VANETs) have been envisioned to provide increased convenience and efficiency to drivers, with numerous applications ranging from traffic safety, traffic efficiency to infotainment [1, 2]. In [10], coalitional games in partition form have been used for modeling the cooperation between SUs in cognitive radio networks, and the SUs in each coalition jointly sense the spectrum and coordinately access the PU channel for improving the total performance. We propose a coalition formation game with non-transferable utility for modeling the cooperation between OBUs, which jointly considers the performance of cooperative sensing and the throughput of channel access.
