City crisis response system based on mesh wireless self-organization network

Nowadays the international world is full of dormant enormous crisis, so the crisis response system is to be more thought of. This paper introduces how to use the mesh wireless self-organization network to monitor the city when the crisis happens and establishes the system network structure. The crisis response system adopts the access/one as the mainly wireless communication means and uses the wireless mesh networks for data transmission medium. The characteristic of the system is self-organization, no centre, multi-hop routing and dynamic topology. When the electricity is cut off or people can not use the mobile-phone, the crisis response system can rapidly monitor the place where the disaster happens and implement the exchange of information between the command centre and the disaster spot.
