After a major disaster, the present communication system fails in providing
the services in the affected area. No means of communication proves to be
more dangerous as the rescue and relief operations become more difficult.
Our current research is about establishing a network in such a disaster-prone
area, which would facilitate to communicate and carry out the rescue
missions. This research project used Java to create a fire-chat application and
used it with the smartphone android system. It used Bluetooth model HC-05
linked with Arduino UNO by the SPI interface to connect Arduino with the
smartphone. The FR-model HCW69 connected with Arduino by using
UART to transceiver the message. The microstrip antenna 915 MHz
connected with the FR-model HCW69 to give us more distance. The
maximum effective range of the transceiver was 1 kilometer, to communicate
by forming a mesh network. This application is helpful in the case when the
smartphone is out of service; it (smartphone) can be communicated
connected to the other nearby users with a message.
