It also can improve undesirable phenomena in traditional MANET routing protocols, such as disconnected and instability problems caused by low energy. 　　At first, we propose a stable-path routing protocol. Because of energy of the node is limited, we will select an appropriate path via packet screening method. So that intermediate node will select the best packet to broadcast. Hence a stable path with appropriate distance will be found. In addition, the packet of countdown times will be effetely adjusted to prevent the flooding phenomena in transmission. Second, we propose an energy-aware routing repair technology. When the destination node left the original place, it will lead to break up of the transmission path. At this time, we use an energy-aware routing repair technology which can find a stable route to reduce re-search time of path. Finally, the performance comparison of our proposal with some existent routing protocols will be given. 　　The contributions of our research are as follows: (1) In our protocol, we find a stable energy path with appropriate distance to improve the stability phenomena in transmission. (2) Through the packet screening method, the amount of packets and the load of paths will be reduced. In addition, the flooding phenomenon will be prevented via the effective adjusted of countdown time of packets, too. (3) We propose an energy-aware repair routing technology to find a stable route to reduce the re-searching time. 　　Finally, we trust the transmission will be more stable via our proposed method. The results of our research in thesis shows that it will be much helpful to future research in the routing protocols of MANET.
