Providing Vehicular Infotainment Service Using VHF/UHF TV Bands via Spatial Spectrum Reuse

Abstract

In this paper, we identify the potential of the television bands to be used for providing vehicular infotainment service. Specifically, content delivery from the roadside unit to vehicular users is conducted by exploiting the spectrum holes, which is also referred to as spatial spectrum reuse. In this manner, the spectrum utilization efficiency is improved and the digital television service is not interfered. We first give a thorough description on such vehicular content delivery network and indicate the major design issues. After that, we respectively develop user and resource models tailored for our scenario by considering their characteristics and formulate the resource allocation as a system throughput maximization problem based on these models. For practical implementation, we devise a vehicular content delivery protocol incorporating a dynamic spectrum access algorithm and a maximal frame size design method, both of which aim at throughput and spectrum efficiency enhancement. Extensive simulations are conducted and the numerical results show the system performance is improved with our approaches.Index Terms-VHF/UHF television (TV) bands, spatial spectrum reuse, dynamic spectrum access (DSA), vehicular service, content delivery.

Advancement in infotainment system in automotive sector with vehicular cloud network and current state of art

“…It has been reported that usage of television bands can facilitate better relaying of service. The work carried out by Chen et al [20] has specified that reusing the spatial spectrum can assist in relaying data for infotainment services. However, the only difference it makes with other conventional approach is that-conventional approaches data is restricted to core internet network (i.e.…”

Framework for Infotainment System for Processing Massive Data Stream of Critical Online Services

“…The work of Felice et al [24] has presented a design of the infotainment system that uses self-healing mechanism in order to support critical application. Chen et al [25] have used television spectrum bands for relaying services over infotainment system. Luddecke et al [26] have used Bayesian network in order to model an infotainment system.…”

WhiteFi Infostation: Engineering Vehicular Media Streaming With Geolocation Database

“…For the up-to-date research works, in terms of the vehicular content disseminate with the support of white spaces infrastructure, Yu et al [13] studied the bandwidth efficient and rate-adaptive video delivery by using the dynamically sensed TVWS channels. By fully considering the TVWS spatial spectrum reuse, Chen et al [25] introduced a vehicular Infotainment service provisioning approach with the goal of content delivery throughput maximization and spectrum efficiency enhancement. A. Achtzehn et al [26] only considered the delaysensitive emergency safety message (ESM) dissemination by utilizing the TVWS channels.…”
