As long as the power consumption decreases, the network life extends. Thus, the way to reduce the power consumption becomes an important objective in the ad hoc network domain. To reach this objective, various power-saving algorithms are proposed in the direction of adjusting the power factors. On the other hand, these algorithms don’t consider about the sending sequence of the packets. In the real world, the power consumption of transmitting a packet may vary by time. In other words, the packet deliver sequence may affect the power consumption of sending a packet. In this essay, we proposed a fair queuing algorithm with power saving, as known as Power Saving Start-time Fair Queuing (PSSFQ). We reach the goal of power saving with the respect of resorting the packet deliver sequence. The conception of our proposed algorithm is to find out the packet deliver sequence with the minimum power consumption. We practice the conception by modifying the existing fair queuing algorithm. The Start-time Fair Queuing (SFQ) is chose as our base algorithm. We evaluate the performance of the proposed algorithm by simulations. The result shows that the consideration of the packet deliver sequence can reduce the power consumption of transmission.
