The invention discloses a mobile Ad-hoc network routing method capable of realizing dynamic high energy efficiency. The method comprises the following steps: firstly, according to the node position information and the radio transmission distance, determining the grid of the nodes; then according to the maximum battery remaining capacity and the minimum mobility principle, selecting from the grid the grid management node and the grid candidate node; further, according to the minimum spanning tree algorithm, obtaining the distance based shortest path from the source node to the destination node; and setting the initial transmission power of the node and dynamically adjusting the transmission power of the node in the data forwarding process based on the distance between adjacent nodes. The method proposed in the invention can increase the stability and the reliability of the routing path, increase the adaptive ability to the mobility of the network and reduce the probability for data packet loss and the power consumption in data transmission.
