An intelligent infotainment dissemination scheme for heterogeneous vehicular networks

In a vehicular network, applications are expected to be aware of network conditions and be adaptable to the varying environment in order to achieve the acceptable and predictable performance. Moreover, the establishment of vehicle infotainment system in a heterogeneous vehicular network needs to pay special attention to the distinctive network characteristic in wired/wireless networks, such as dynamic topology and less available bandwidth, and the exploitation of the underutilized peers’ resources to support large-scale services. This work thus proposes a service-oriented information dissemination scheme for vehicle infotainment system to ensure the possibility of heterogeneous vehicular communication and a framework for delivering real-time services over an IP-based network is provided to assure interoperability, roaming, and end-to-end session management. The main focus of this work is to implement an adaptive vehicle infotainment system, in which cache relay nodes ((Xiao, Zhuang, & Liu, 2005)) can be intelligently determined. Fuzzy logic inference system is employed to determine appropriate cache relay nodes to cache infotainment data streams and distribute them to different peers through service-oriented architecture. The experimental results demonstrate that effectiveness and practicability of the proposed work.
