The fixed communication interruption easily occurs in extreme disaster situation, so it needs a robust mobile Ad hoc wireless communication to deliver the rescue information with high quality and efficiency. But the widespread excessive energy consumptions loaded in mobile Ad hoc wireless routing network have become the restriction bottleneck of its application. Based on the routing protocol of AODV, this paper proposed a routing algorithm of AODVSE energy-saving protocol, and studied its effects of the working performance on mobile Ad hoc wireless network. The simulation results showed that the AODVSE protocol could be better to improve the energy-saving performance than AODV and DSR protocols by reducing the routing expiration time and the routing load and extending the network lifetime, in order to help to implement the accurate and immediate rescue.
