When an amount of users are accessing the wireless network with multiple Access Points (APs), a challenge is how to allocate the wireless network resources effectively. A utility function is proposed to evaluate the effectiveness, and a Resource Allocation Algorithm (RAA) is introduced to solve this problem. The algorithm firstly calculates the utility values from a user’s request to different available APs. Then it stores the results with request ID and AP ID in a pair. In each allocation time slot, request-AP-utility pairs are arranged in utility value from high to low. Then the available service resources are allocated to the requests properly by a Fast Resource Allocation. Compared with Fair-Method in the same simulation scene, RAA gains 200% performance in delay with only 15% losing of load balance.
