Now the existent schemes to optimize the performance in wireless LAN is mainly based on centralized algorithms, which aim at family user. This paper proposes a distributed power control algorithm for large scale use. The scheme works based on prediction and sub-traverse, cooperating with a small granularity schedule which is called t-scale timeslot schedule. The simulation on NS2 shows that the scheme reduces the interference among access points and boosts the throughput of the whole network by 3.1 Mb/s(unsaturated) or 1.0 Mb/s(saturated), while the variety of the network can be responded timely.
