Nowadays GSM system is the most essential technology in cellular network communication. This will get damage due to some harmful effects such as cyclones etc., Network capturing using GSM manual system will leads to time delay. So this affects the emergency communication in disaster area. Then the antenna will not be reused when using GSM antenna in higher buildings. It is a fixed monopole antenna. If it is dismantled, the entire system will be affected. So UAV is implemented to avoid the availability problem of network in disaster area. The emergency communication is provided by SMS or voice call. Software Defined Radio (SDR) is a platform which is used to run BTS. Here SDR acts as a small base station. To transmit and receive the signal, the Universal Software Radio Peripheral (USRP) is used. It acts as a transceiver device. The existing system will not rescue the people those who are invisible sto search and rescue mission. In this proposed system, we developed the sound sensing technique to sense, monitor and record the audio signal of the affected person in invisible area. This involves implementing a signal processing system for audio sensing by using audio sensor network. It consists of microphones to share the information. UAV will record the information from microphones.
