Abstract: The routing protocols have been the focus of the researchers for Ad hoc network study in recent years. How routing protocols can be adaptive to the rapid change of the Ad hoc network topology is the most important of all their care. That QoS performance of Ad hoc network is improved by use of power control technology is put forward in this article. And this algorithm is described in detail in the paper. Some key parameters of calculation method used in new algorithm are provided, and how the new algorithm is implemented in actual equipment. new algorithm is also demonstrated in the designed simulation model in OPNET software. The result of simulation proves that the new algorithm can be adaptive to the rapid change of the Ad hoc network topology.
