Raptor codes‐aided relaying for vehicular infotainment applications

Abstract

Even though the main motivation behind wireless access for vehicular environments was to support time-sensitive safety applications, typical Internet applications are also required to attract private investment that would help expand the network and reduce the cost of implementing the systems. It is well known that the Automatic Repeat reQuest scheme used in the current IEEE 802.11p standard is highly inefficient for vehicular applications. Therefore a raptor-coded decode-andforward relaying scheme with an efficient feedback channel, named the 'r-DF scheme' for infrastructure-to-vehicle infotainment applications is proposed in this study. The scheme is evaluated using a multi-layered simulator combining a realistic IEEE 802.11p physical and MAC layer design considering the presence of interference in a highway and an urban scenario. The simulation shows that the scheme achieved up to double the average aggregate throughput and tens of decoding time improvements over the state-of-the-art.

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

“…The multiple display position considered was on radio interface, phone interface and HVAC (Heating, ventilation, and air condition) interface. Abdullah et al [23] have used raptor codes in order to assess the relaying services along with using decode and forward scheme. A simulation-based scheme was adopted over conventional IEEE standard of VANET as well as design of MAC layer to find increase in its throughput.…”

“…Rene et al [27] have presented architecture towards improved infotainment uses using deep packet inspection. Apart from this, the other approaches are architecture with heterogeneous supportability (Sadek et al, [28]), android-based (Udovicic et al [29]),a nd raptor codes (Abdullah et al [30]).…”
