Abstract:
Jini™ network technology provides a protocol and system architecture whereby
devices and services are added to the vehicle in a completely spontaneous and
(often) autonomous way. When first launched, Sun Microsystems’ Jini
technology captured the imagination of automakers looking to seamlessly
integrate new product and service offerings into automobiles. At JavaOne 2000,
Ford demonstrated a Jini technology-enabled vehicle. However, at the time Jini
technology required more device storage than was available, limiting its use for
in-vehicle applications.
PsiNaptic™ contributed significantly to Sun’s initial vision for Jini technology on
all devices by reducing its footprint to less than 100 kilobytes. Exciting
opportunities now exist for this micro-version of Jini technology in automotive
telematics applications. Furthermore, this technology is applicable to many
resource-constrained or mobile devices. Telematics systems can interact with
these devices as they enter the vicinity of the car, allowing applications, services,
and information to be utilized when and where they are needed.
Two scenarios are presented that exemplify the need for Jini technology in
automotive systems. In the first, Jini technology is applied to the late-binding
problem inherent in in-vehicle subsystems. The second scenario addresses the
management and control of mobile devices (such as cell-phones and PDAs) that
come into contact and inter
