| Research Abstract |
We developed the network constructing technology with only wireless nodes at the disaster scene where the network infrastructure is down. We proposed the efficiently broadcasting method which selects the receiver node from multiple receivers in order to broadcast the information to receivers efficiently and certainly. And the novel security camera system was proposed which uses the efficiently broadcasting technology. Finally, we introduced the IPv6 technology to the ad-hoc network. Using IPv6, the nodes know the link status between neighboring nodes in detail quickly. So our system has the robustness against frequent moving of nodes.
