Vehicular Wi-Fi Offloading in Heterogeneous Vehicular Networks: Techniques and Challenges

摘要: The increasing use of smartphones, tablets, and other vehicular network applications with varied capabilities the associated growth in all types data-hungry multimedia services pose a significant challenge to cellular infrastructure operators. Vehicular Wi-Fi offloading (VWO) is one potential solutions for traffic. Several techniques through ad-hoc networks are proposed literature. Thus, this paper reviews several state-of-the-art VWO techniques. We categorize based on application requirements medium used offloading. Two groups identified. All that depend roadside unit as media classified vehicle-to-infrastructure-based those opportunistic vehicle-to-vehicle (V2 V) called V2 V-based present comprehensive architecture performance metrics derived from mobile-data metrics. also elucidate important issues be incorporated designing together future research directions domain.
