Wireless Media Streaming Over IP-Based In-Vehicle Networks

We investigate a heterogeneous IP-based network architecture for in-vehicle communication. The wireless technology is an interesting candidate for in-vehicle communication, since it reduces the cabling effort and consequently the cost. In this work, a peripheral wireless network based on the IEEE 802.11 technology is investigated for media streaming in the car. FEC-based multicast and unicast transmissions are studied and compared for the same communication scenarios based on their QoS performance and resource requirements. Moreover, the frame bursting mechanism from the IEEE 802.11e standard has been applied to improve the throughput of small packets over in-vehicle wireless channels.
