In Mobile Ad Hoc Network (MANET), due to the mobility of the nodes it is difficult to find the route which can maintain the whole process of data transmission. Therefore, it is very critical to balance, maintain and repair the route within the mobility of nodes and the limited battery energy. Currently there are many protocols from different aspects to solve this problem. This paper proposes a new improved routing protocol, which is based on delayed replay program, and its main objective is to create the stable routing protocol based on hop AODV, node mobility speed and node communication state. The discovery process of improved routing protocols only let the low-speed node forwards the RREQ package, and re-routing request packet delay broadcast according to node’s degree of busy. NS2 simulator is adopted to assess the performance of using the program. Simulation results show that the proposed method has better performance than conventional methods, which mainly shows in better performance on the aspects on packet transmission rate of improved protocol, control overhead and end to end delay.
