Enabling efficient and wide-coverage vehicular content distribution over TV white spaces

Abstract

Enabling efficient vehicular wireless connections with wide coverage for vehicular applications has gained significant attentions in both academia and industry. In this paper, we study the TV white spaces (WS) supportive vehicular content distribution with Geolocation database, which is referred to as WhiteFi Infostations. Taking into account both the realistic content distribution requirements for delay and throughput constraints in vehicular applications and the vehicular mobility as well, we propose a mobility-aware contention-free multi-polling access scheduling scheme to support both the deadline-driven and delay-tolerant vehicular content distribution applications. Through extensive simulations with real-world empirical TVWS data and urban vehicular traces, we demonstrate that our proposed vehicular content distribution solution can well support both the deadline-driven and delay-tolerant vehicular tailor-made services in vehicular ad hoc networks (VANET).
