The third generation cellular system will provide high bandwidth data servi
ce and multimedia applications are proposed on the high-speed data link. On
tile other hand, cellular handsets are getting: equipped with a short-rang
e radio communication device that is mainly targeted to connect cellular ha
ndsets to computers. In this paper, we propose a percolating data delivery
mechanism for a cellular-ad hoc integrated network utilizing multicast/broa
dcast communication, which is endorsed by data synchronization, and single-
hop ad hoc networks for information shower/exchange services. The mechanism
lessens data traffic in both tile cellular and the ad hoc network for data
delivery and tolerates unexpected disconnection in the ad hoc network. The
mechanism also compensates data delivery in areas out of tile cellular ser
vice. Our implementation of the data delivery mechanism utilizes Bluetooth
for an ad hoc network configuration, and delivers data in the cellular netw
ork to the Bluetooth ad hoc network via the data synchronization mechanism.
We evaluate communication traffic and delivery time on the prototype syste
m and discuss about the efficiency of the mechanism.
