Abstract: Intra-vehicle wireless sensor networks (IVWSNs) enable sensor technologies to be integrated into vehicles and provide part-cost, assembly, and maintenance savings, as well as fuel efficiency through the elimination of wires. Ultra-wide band (UWB) communication is considered a competitive candidate for IVWSNs. Extensive analysis has been done for indoor and outdoor propagation, but the analysis of IVWSNs environments has rarely been studied. In this paper, the error-rate performance of UWB propagation for these IVWSNs is investigated and compared under different transmission schemes. And we also study the effects of some parameters on communication performance, such as the number of rake fingers and direct sequence spread factor of an impulse radio system, the cyclic prefix size of a single carrier block transmission with frequency domain equalisation system, and the delay line time of a transmitted reference pulse cluster autocorrelation receiver. Study results offer valuable insight for the realistic IVWSNs.
