Towards performance of ad hoc in Car multimedia service framework

With the rapid proliferation of wireless services into automotive domain, it is of paramount importance to understand how reliably data can be sent through a custom wireless local area network (WLAN). Thanks to a large body of research, WLAN throughput under saturated and non-saturated traffic condition has been well understood. In this paper, we preset the performance model for ad hoc multimedia service framework, called mCar, based on IEEE 802.11. _With help of application prototype, we show that in an ad hoc multimedia WLAN with multi-packet reception (MPR) capability, saturation throughput scales superlinearly with the MPR capability of the network.
