In this paper, we proposed a hybrid communication approach for disaster recovery system. Playing an important role in rescuing victims, the communication system in the disaster area is usually destroyed. The mobile ad-hoc network (MANET) can replace the original system. MANET can be deployed in the form of peer-to-peer (P2P) approach or infrastructure-based (IB) approach. However, both approaches still have limited flexibility and reliability. Our hybrid approach overcomes the limitations by combining advantages of P2P approach and those of IB approach. The hybrid approach allows victims to directly communicate to rescuers in the disaster area. Since victims need immediate helps from rescuers, appropriate destinations must be selected. Our design of hybrid approach allows victims to quickly send messages to the nearest rescuers without compromising the traffic to a base station. The experiment shows that our hybrid approach provides more than 98% of packet delivery ratio to rescuers.

Therefore, one of the challenges to communication approach is to select destination for each victim. To appropriatel we also proposed an algorithm to select the experimental results show that our algorithm than 98% of packet delivery ratio to rescuers This paper is organized as follows. S related communication systems in disaster s our previous work. Section III descri communication approach. Section IV giv design of the destination selection. Secti performance evaluation and the overhead i the Section VI concludes the paper. Fig 8 Percent of packets arrived at rescuers Fig 9 Beacon overhead
