Abstract

A vehicular wireless network is formed by connecting a plurality of sensor devices and automobile subsystem devices to a processing unit with wireless links. Similarly, a vehicular wireless network is formed by connecting a plurality of sensor devices and automobile subsystem devices located in various compartments of an automobile to a signal interface located in the same compartment with wireless links. The signal interfaces and processing unit are then linked by a bus that is installed to run through all the automobile compartments.
