Skipping-based handover algorithm for video distribution over ultra-dense VANET

摘要: Abstract Next-generation networks will pave the way for video distribution over vehicular Networks (VANETs), which be composed of ultra-dense heterogeneous radio by considering existing communication infrastructures to achieve higher spectral efficiency and spectrum reuse rates. However, increased number cells makes mobility management schemes a challenging task 5G VANET, since vehicles frequently switch among different networks, leading unnecessary handovers, overhead, ping-pong effect. In this sense, an inefficient handover algorithm delivers videos with poor Quality Experience (QoE), caused frequent that leads high packets/video frames losses. article, we introduce multi-criteria skipping-based called Skip-HoVe. It considers skipping mechanism coupled prediction, Service (QoS)- QoE-aware decision, meaning handovers are made more reliable less frequently. Simulation results show Skip-HoVe to deliver Mean Opinion Score (MOS) 30% better compared state-of-the-art algorithms while maintaining rate around 2%.
