But the electric consumption of the battery is very limited, and can only maintain wireless network device short time operation. So the relevant topic of wireless power saving appears. Much research utilizes scheduling method prevent data from colliding in the air, and increase channel utilization. But this kind of scheduling methods are all by central control. Though scheduling is not the central control, can't reduce translation times of scheduling either, so unable to be effective to save the electricity. Because most scheduling method only consider that will reduce control package, and neglect translation of wireless device. So we think if translation can be regarded as the basis of scheduling, the electricity of wireless device can utilize effectively. For make wireless device to be effective with the limited electricity and raise throughput, we propose a power saving MAC protocol that can be operated under Multi-Hop environment, and utilize translation times to economize more electricity. Make wireless device not only can economize the electricity , but also can improve wireless transmittion rate. And improve the practicability and convenience of wireless mobile device.
