Skip to Main Content Wide range wireless networks often suffer
from annoying service deterioration due to fickle wireless
environment. This is especially the case with passengers on long
distance train (LDT) to connect onto the Internet. To improve
the service quality of wide range wireless networks, we present
the DragonNet protocol with its implementation. The DragonNet
system is a chained gateway which consists of a group of
interlinked DragonNet routers working specifically for mobile
chain transport systems. The protocol makes use of the spatial
diversity of wireless signals that not all spots on a surface
see the same level of radio frequency radiation. In the case of
a LDT of around 500 meters, it is highly possible that some of
the spanning routers still see sound signal quality, when the
LDT is partially blocked from wireless Internet. DragonNet
protocol fully utilizes this feature to amortize single point
router failure over the whole router chain by intelligently
rerouting traffics on failed ones t
