The following three points are obtained. Where, victim detection system means a system for rescue operation which the head investigator proposed. The system consists of multi-robots and a monitor station. For the purpose to maintain the network, each robot does the autonomous pass recovery in this system.(1)The investigation of the reconnaissance into distant space.The reconnaissance into distant space is proposed and the performance is confirmed. The proposed scheme consists of the sequential movement of robots to the destination in the space, and the random walking of them after the arrival at the destination. It is confirmed by computer simulations that in spite of breakages of communication path, the breakages are recovered and the reconnaissance is done successfully.(2)The investigation of wide area exploration.The wide area exploration is proposed and the performance is confirmed. The proposed scheme consists of the classification of robots into search robot (SR) and relay robot (RR) by themselves, and the movement of RR to maintain the communication path between MS and the master SR which the RR selects among SRs. The system performance is confirmed by the computer simulations.(3)The investigation of real time streaming of dynamic picture imageThe synchronized QoS routing is already proposed for real time streaming of dynamic picture images in ad hoc network. However, because of void VCs decrease the rate of successful communication when network topology changes frequently, the conventional scheme is not applicable to the rescue operation. To resolve this problem, the modification of frame structure is proposed in the synchronized QoS routing. The system performance is confirmed by computer simulations.
