Abstract
The signal intensity based wireless terminal access mechanism is the key cause of imbalanced load of WLAN. In the environment where users are densely packed, such as banks, office buildings and malls, load imbalance will severely decrease the quality and source utility rate of WLAN, thus the node load balance strategy becomes increasingly in demand to solve the problem. First, this paper studied the mainstream node load balance technologies and proposed an evaluation model which identifies and measures the level of load; next, the load level gain calculation model was designed and the prediction-based load balance and resource adjustment strategy was put forward; at last, the load balance mechanism ST-WLB was enabled and the test result shows that it can improve the performance by 10% without excessive costs.
