In this paper we conduct a feasibility study of delay-critical safety applications over vehicular ad hoc networks based on the emerging dedicated short range communications (DSRC) standard. In particular, we quantify the bit error rate, throughput and latency associated with vehicle collision avoidance applications running on top of mobile ad hoc networks(More)
Ultra-wideband (UWB) technique attracts attention from automotive manufacturers as a potential way to construct intra-vehicle wireless sensor network. This paper reports our preliminary effort in measuring and modeling the UWB propagation in the commercial vehicle environment. Two cases of time domain channel measurement results are reported. In one case,(More)
With its fine immunity to multipath fading, ultra-wideband (UWB) is considered to be a potential technique in constructing intravehicle wireless sensor networks. In the UWB literature, extensive measuring and modeling work have been done for indoor or outdoor propagation, but very few measurements were performed in intravehicle environments. This paper(More)
We propose using a wireless network to facilitate communications between sensors/switches and control units located within a vehicle. In a typical modern vehicle, the most demanding sensor will require a latency of approximately less than 1 msec with throughput of 12 kbps. Further, the network will need to support about 15 sensors with this requirement. The(More)
Automotive wiring harnesses that provide the wiring infrastructure for electrical and electronic sub-systems inside vehicles have grown in size over the years. Significant engineering challenges are posed due to increased weight / decreased fuel economy, increase in production steps, increased cost and labor in harness manufacturing and installation,(More)
With the increasing number of sensors in modern vehicles, using an Intra-Vehicular Wireless Sensor Network (IVWSN) is a possible solution for the automotive industry to address the potential issues that arise from additional wiring harness. Such a solution could help car manufacturers develop vehicles that have better fuel economy and performance, in(More)
