Abstract:
1. A method for implementing a load balancing system in a wireless area network, comprising: step 1, initializing a load balancing group of online access points in the wireless area network, self-organizingly selecting one of the access points from the online access points in said load balancing group as a load balancing agent center; and step 2, each access point of said balancing group managing and processing load balance in accordance with a load level and balance optimizing strategy, so as to implement the network load balance; wherein the access point with a lowest current load level in the load balancing group is selected as the load balancing agent center, and after the load balancing agent center is selected, other access points in the load balancing group act as non-load-balancing agent centers, and wherein only said load balancing agent center needs to record the load information of other access points acting as the non-load-balancing agent centers in the same load balancing group, while the access points acting as non-load-balancing agent centers just need to acknowledge the location of the load balancing agent center, wherein load information is reported to the load balancing agent center when the load of the access points acting as the non-load-balancing agent centers is changing, and the non-load-balancing agent centers obtain network load information of the load balancing group from the load balancing agent center, and load balancing management is conducted by combining with load balance information locally stored; and wherein in step 2, a threshold strategy is used for the access points, each of which including the access points acting as the load balancing agent center and the non-load-balancing agent centers, wherein an upper load limit MAX and a lower load limit MIN are set respectively to conduct management and processing of load balance as follows:
