Paper Abstract:
|
In Japan, the Earthquake Early Warning (EEW) was started for an aim of fending off a major disaster by people's
preparation. To get this system more useful in Internet, this paper proposes a new EEW system using peer-to-peer (P2P)
networks. P2P networks have an advantage of the load distribution. However, using P2P networks as the infrastructure
has some drawbacks: low reliability and transfer latency. In order to solve these drawbacks, this paper proposes the
reliable geography aware P2P multicast tree, which can give the certainly and fast warning to all registered users. This
multicast tree is periodically improved and maintained its reliability and transfer latency by the autonomous dynamic
reconstruction based on the performance of nodes. Additionally in this phase, the geographical element is evaluated
because of the earthquake propagation mechanism. Note that this system is applicable not only to the EEW system but
also to every system which need its reliability and transfer latency. |
